Experience of simulated training

Experience of simulation training (5 selected articles)

When we have new inspiration after reflection, we can usually write down our own experiences, which is conducive to our continuous improvement. So what is a good experience? The following are my collected simulation training experiences (5 selected articles) for reference only. Let's have a look.

Simulation training experience 1 After several days of simulation practice, we practiced the start-up simulation of centrifugal pump, heat exchanger, rectification tower, atmospheric and vacuum distillation unit of petroleum and boiler. Through the simulation practice, we can understand the basic unit operation methods, enhance the understanding of the process, be familiar with the design and operation of the control system, learn the operation of complex control systems, learn the safety standard operation, and enhance the training and troubleshooting capabilities.

(1) Be familiar with the process flow, operating equipment, control system and driving rules before the simulation operation.

In the boiler heating device. The boiler body consists of economizer, upper drum, convection tube bundle, lower drum, downcomer, water wall, superheater, surface desuperheater and header. There are four groups of economizer, the main function of which is to preheat boiler feed water, reduce exhaust gas temperature and improve boiler thermal efficiency. The upper drum is composed of shutters, cyclone separator and water level gauge. Its main function is to separate steam from water and connect the heating surfaces to form a normal cycle. The main function of the water wall is to absorb the radiant heat of the furnace. Superheater is divided into low temperature section and high temperature section, and its main function is to change saturated steam into superheated steam. The main function of surface desuperheater is to adjust the temperature of superheated steam.

(b) Distinguish the sequence of each operation.

There are two main reasons why it is required to distinguish the sequence of operation procedures: first, to consider safety in production, not reversing according to the operation sequence will cause accidents; Secondly, due to the law of the process itself, the vehicle can't run without operating sequence. Therefore, the order between the operation steps is very important and cannot be changed at will.

In the boiler unit, it is necessary to start the water supply device first, then make preparations for the boiler ignition, then heat the boiler with high-pressure gas, then merge the gas with the boiler, then gradually increase the boiler load, and finally introduce flue gas to make the boiler run normally.

(3) the operation should not be ups and downs.

In large-scale chemical plants, there is a large inertia lag characteristic regardless of the changes of pressure, material level, flow rate or temperature. If we greatly adjust the valve when the regulated variable deviates from the expected value, because of inertia and lag, we can't see the change for a while, so we can't see the change for a while. But after a certain period of time, the regulated variable exceeds the expected value, and we are also eager to pull it back, which leads to repeated shocks of the controlled variable and is difficult to stabilize.

For example, in the water injection of deaerator of boiler unit, because the rise of liquid level is greatly delayed, it is difficult to stabilize the liquid level of LIC-02 at 400mm if the valve is opened too wide.

(4) Start from the low load, reach the normal working condition, and then slowly increase the load.

It is a basic safety rule to start with low load and then gradually increase the load, whether it is for dynamic equipment or static equipment, whether it is for a single device or the whole process.

For example, for a boiler unit, the water quantity is controlled at 10t/h first, then reaches 15t/h after gas mixing, and finally reaches 65t/h, thus gradually increasing the production load, which can not only effectively exert the maximum safe production load of equipment, but also realize safe start-up, and prevent accidents, equipment damage and heavy losses during start-up.

(E) establish the concept of material balance

In a specific unit, the total amount of incoming and outgoing materials is dynamically balanced, and so is energy. Therefore, through this balance, we can indirectly judge the running state of the equipment, reasonably adjust the start-up steps and grasp the start-up opportunity of each link. For example, in the boiler simulation unit, because the liquid level of the boiler has been adjusted to be automatic, the evaporation water quantity and inflow water quantity of the boiler reach a dynamic balance. In the process of boiler boosting, we can judge the amount of steam produced by judging the water inflow, so as to reasonably grasp the opportunity of gas merging.

Through the simulation experiment, we can have a deeper understanding of the technological process of production equipment, understand the function of combining theory with production practice, improve the operation level under the condition of reducing the interference to actual production, let us master the handling methods of some common accidents, reduce unexpected accidents and misoperation, and make it convenient for us to master the production operation skills of different positions, achieve the production operation requirements of one person with more posts, and improve our overall production operation skills.

The experience of simulated training 2 Looking back two years, the training was very perfunctory. The teachers hurried into the classroom, let's practice quickly, arrange the questions in a hurry and hand them in two weeks later, and then leave the classroom in a hurry ... so I don't know what college training is. In my mind, training is to write a report and hand it in every half month. It's that simple. Unexpectedly, this semester, when we were all on holiday, we suddenly arranged a training. I was wondering if I would fool around like I did in previous years. Unexpectedly, it is really different from what I expected, and it is very different from previous years. For us college students who have been trapped in the ivory tower for three years, what is the structure, how to operate and what is the process of the enterprise are completely unclear, or even have no clue. A simple training course, of course, can't let us really understand the face of the whole enterprise.

As college students who are about to graduate and enter the society, our practice is almost zero. Maybe some students will take part-time jobs, set up their own stalls or explore the society in other forms, but what we can reach now is only the tip of the iceberg. What is the real workplace, enterprise and society like? We can't answer, but how can we fight an unprepared battle? Enterprise simulation training may have entered our classroom in this way.

Two training courses, each with its own emphasis. On the first day, whether it was the departmental role assignment in the morning or the kettle assembly simulation training in the afternoon, it was assumed that we had entered the enterprise. Especially in the afternoon training, our group unfortunately came last. The main problem is communication with the outside world. Now, it seems as simple as we exchanged two parts for one part. However, if this problem appears in the real workplace negotiations in the future, we will undoubtedly be defeated, which is totally undesirable. We have so many screws, but we can't replace them with those we don't have. Parts, then we will fully play the role of "screw". We have not fully understood the simple truth of equal exchange and taking what we need. The second training focuses on the training before entering the enterprise-how to make a resume. Resume is a stepping stone to our job opportunities. There are many ways to find a job in today's society, but resumes are suitable for each one. At each stage, when the recruiter opens the first class of the recruitment email, the resume comes into view. Therefore, the quality of resume directly affects the success of job hunting. It can be said that resume is our first face in the enterprise. Making a complete and effective resume is the key for us to enter an enterprise and the first step to success.

I benefited a lot from two trainings. The most important thing is unity and cooperation. In an organization, many times, we can't choose cooperative members. So it is likely that the members in the group have different abilities. If you are a leader, you need good cohesion ability at this time, which can unite the characteristics of most team members. At the same time, leaders are required to have the ability to get along well with and communicate with different people. If the leader doesn't set an example in all aspects at first, there will be many bad consequences. For example, in a collective, if members lack the most basic trust, then members always want to protect themselves in front of their peers, so they cannot argue with each other. The so-called practice of preserving our sanity hangs high as long as it has nothing to do with our own interests, that is, we don't want to be responsible for each other. Then, who else will be responsible for the collective development? This kind of team development is worrying. Therefore, in order to strengthen cooperation with others, we must first ensure the loyalty, responsibility and willpower of collective members, and also have a sense of honor and mission to our own team. Leaders must trust all members of the team, be honest with each other, and have a heart-to-heart conversation without reservation; Work closely with every member of the team until the whole team can work closely together; Analyze the motivation of each member to finish the work, study their urgent needs, brainstorm according to their motives and needs, listen to other people's suggestions, and don't go it alone. As the saying goes, "If people are United, the mountains will move." At the same time, leaders should have the demeanor of leaders, be strict with members in their work, care about members in their lives, and do a good job in communication and coordination among team members, so that the whole team can operate in an orderly and harmonious way like a machine.

Of course, in the process of collaboration, one task is particularly important, and that is communication. Communication between people can bring about an understanding of life. In our daily life, interpersonal communication is an indispensable activity. In the process of communicating with others, we encourage and motivate ourselves. If we want to give someone a glass of water, we must have a bucket of water or more. Instead of pleasing others, it is better to maintain a good state of harmony, interaction and mutual assistance with your heart and induce each other through good communication. If we have empathy, everyone will be happy. Improving through mutual encouragement is a great pleasure in life. For example, explaining something to a friend requires learning, thinking and refining in order to do it better, which is itself a process of progress. The function of communication can help us reach a certain consensus, and everyone has the right to reserve opinions. This is the truth that "the villain is not harmonious, and the gentleman is not harmonious."

The last practical training in college life is over, and we are about to set foot on the society, which is a test of our learning achievements.

Experience of simulation training 3 After two weeks of simulation training, we practiced the simulation of centrifugal pump, heat exchanger, liquid level control, cold start of distillation column, normal shutdown and corresponding accident treatment. Through this simulation exercise, the basic unit operation method; Enhanced my understanding of the process, and then more familiar with the design and operation of the control system. Let me have a deeper understanding of centrifugal pumps, heat exchangers, distillation columns and so on. Through this chemical simulation practice, I have gained a lot, and have a certain understanding of the process flow and control system, and basically mastered the law of starting and stopping.

When I first came into contact with chemical simulation software, I felt very confused and curious. In the later internship process, I first carefully read the specific process of internship in the textbook and basically understood the operation process.

Especially in the practice of complex chemical processes, such as distillation column units, I think we should:

(1) Read the corresponding process operation in the textbook carefully and understand each step, because the familiarity of the process is very important in the operation. If you are not familiar with the process, you may go astray, make mistakes in operation, get twice the result with half the effort, and you will not be able to master what you need to learn well.

(2) In the face of a complicated technological process, if we can't know their functions, corresponding positions and how far they will go in advance, we may be in a hurry when driving, leading to misoperation. So the most important preparation before driving is to be familiar with the whole process.

(3) Be patient with the operation after driving, and don't rush for success. Only by meeting the process requirements of each step can the next operation be carried out, otherwise it may cause irreparable quality errors. Therefore, in the face of a technological process, it is necessary to understand what the function of this technological process is, what purpose it is to achieve, how to feed each link in the process, what the operating conditions are and what the requirements are. Only in this way can we learn better or master the learning content of our own practice.

In short, through two weeks of simulation practice, I learned a lot, and at the same time, I also learned a lot. In the process of operation, every step of the process operation should be patiently completed to meet the specified requirements, and you should not rush to achieve success, otherwise you will get twice the result with half the effort. We should constantly learn the lessons of failure, consult teachers and excellent students humbly, and sum up experience. In addition, in the future study and life, we should study our professional knowledge more diligently, lay a solid foundation and expand our knowledge, so as to make better use of it in our future work or life and lay a foundation for our future work!

On April 6th, we ended a two-week comprehensive training for modern service industry. In these days, we use the interdisciplinary simulation training system of learning and enterprise management, combined with the comprehensive practical course resource system, to carry out tasks in the panoramic simulation environment of modern enterprise operation.

A series of entity business units and public service units with modern manufacturing enterprises as the core constitute a panoramic modern commercial society, which is divided into industrial zone, administrative service zone, business zone and modern service zone. I was assigned to an accounting firm in the modern service area to play the role of accountant in the business department. Our accounting firm is called Hongde Certified Public Accountants.

Being a salesman in an accounting firm for the first time, I am not very familiar with the roles and responsibilities. I read the relevant information provided by the teacher and the job description issued by the chief accountant, and understand that the accountant in the business department has the responsibility and authority to manage the unit and implement accounting supervision. We Hongde Certified Public Accountants started to register, register tax, open a bank account, and formulate the working system and annual work plan of the accounting firm, during which we encountered many problems. We tried to solve the problems one by one by consulting network materials and discussing with other students, and also learned a lot of knowledge and gained rich practical experience. When dealing with daily business, the relevant customer manufacturing company needs loans. In the process of verifying the authenticity of capital, we have a deeper understanding with relevant client companies, which is convenient for conducting audit business and issuing capital verification reports in the future. Through this training, I deeply realized the importance of teamwork, and my ability to solve problems by myself has also been improved. At the same time, I also feel that my professional knowledge is very weak. However, this simulation training still provides us with a good platform to exercise ourselves. Although a little tired, it is really useful.

The experience of simulation training The five and a half semesters of on-campus chemical simulation experiments are over, and the experimental mood during this period is complicated. It can be seen from here that this experiment has taught me a lot and gained a lot of knowledge and experience that I couldn't get in class alone before. Half a semester's experiment, here I finish this report with a summary and introspection. It is also to commemorate my experimental life at school.

Simulation experiment is a new technology which uses simulator as a tool and uses real-time dynamic mathematical model instead of real factory for teaching practice. Simulator is a kind of artificial equipment based on computer, network or multimedia components to simulate factory operation and control or industrial process, and it is also an environment for dynamic mathematical model to run in real time.

The simulation experiment provides students with ample hands-on opportunities, and they can repeatedly carry out driving and parking training on the simulator. On the simulator, students become the main body of learning. Students can study selectively according to their own specific conditions. For example, design and test different start-stop schemes, test complex control schemes and optimize operation schemes. Various accidents and extreme operation states can be set to improve students' analytical and decision-making abilities in complex situations. Real factories are never allowed to do this. The high-quality simulator has strong interactive performance, which enables students to play their learning initiative in the simulation experiment process and the experimental effect is outstanding. The main content is to select chemical unit operation and typical industrial production equipment, such as centrifugal pump, heat exchanger, compression, absorption, rectification, batch reaction, continuous reaction, heating furnace, catalytic cracking unit in petrochemical industry, atmospheric and vacuum distillation unit and conversion unit in synthetic ammonia. Computers are used to simulate operations.

During the experiment, students can have a detailed understanding of the process flow of the device, the range of process parameters under normal working conditions, the principle of the control system, the functions of valves and operating points, and the start-up procedures, and master the ability of starting, stopping, running and eliminating accidents in typical chemical production processes.

Here I give some specific experimental examples to illustrate the content of our research:

"Rectification" and "absorption" are two unit operations of mixture separation in chemical industry, which occupy an important position in chemical industry. These two parts of the theory are abstract, and only students are taught the corresponding theoretical knowledge in class, which students find difficult to understand; Because there is no physical reference, the teacher also feels a little passive when teaching this part. Therefore, it is particularly necessary for students to carry out corresponding practical classes while studying these two parts.

Through the simulation experiment, after learning the theoretical knowledge of "distillation" and "absorption", the students went to the laboratory to actually operate the sieve plate distillation tower and packed absorption tower. The process of "rectification" and "absorption" in the laboratory is small and concise, which is convenient for students to observe the reaction of substances. In practice, students can not only solve the problems left over from class, but also apply the theoretical knowledge in textbooks to practical operation while operating, observing, thinking and discussing. On the one hand, it improves students' interest in learning and stimulates their enthusiasm for learning; On the one hand, it adds a lot to teaching.

The experimental class plays an important role in our understanding of the two chapters of distillation and absorption. Before the experiment, I heard the "tower" in the class, which was very abstract. It is difficult to imagine the separation process of each component after gas-liquid two-phase contact in the tower. After the experiment, they felt that these two parts were not so difficult.

In addition, through the simulation experiment, students can have a deeper understanding of the technological process of production equipment, understand the function of combining theory with production practice, improve the operation level while reducing the interference to actual production, cultivate high-level talents for enterprises, let students master the handling methods of some common accidents skillfully, reduce unexpected accidents and misoperation, facilitate students to master the production operation skills of different positions, meet the production operation requirements of one person with multiple posts, and improve their overall production operation skills.

During the experiment, we should pay attention to the following questions:

1, before the simulation practice, you must read the teaching materials of chemical simulation experiment carefully to understand the operation content and production background;

2. Be sure to keep quiet; If you have any questions, you can raise your hand and communicate with the instructor alone;

3. The chemical simulation teaching software system is special software, and it is forbidden to change the fixed parameters of the software; It is forbidden to change the original settings of the simulator;

4. It is forbidden to operate on the simulator that has nothing to do with chemical simulation;

5. It is forbidden to operate any foreign floppy disk, CD, removable disk, etc. On the simulator;

6. After each experimental operation is completed, you need to raise your hand to instruct the teacher, and the teacher can only quit after checking and agreeing to record the operation results.

The simulation experiment of half a semester simulated the operation flow of many chemical processes. This experience makes us graduates who are about to face the society and go to work have a profound perceptual knowledge and understanding of various technological processes and related procedures, and also allows us to get in touch with the actual production process of enterprises, and combine the knowledge in books with the actual situation to apply what we have learned. Thank the school for providing us with such a good learning opportunity! I also thank the teacher for his careful guidance.
