Experience of simulated training

3 Excellent experience of simulation training

How to write a standard specification based on the experience of simulation training? According to years of experience in secretarial writing and referring to excellent samples of simulated training experience, you can get twice the result with half the effort. The following are three excellent simulation training experiences for your reference.

Simulation training experience 1

The three-week simulation training ended on Friday afternoon. In this tense and pleasant fifteen days, we mainly used simulation software to make a profound training and simulation experience on the experimental operation and knowledge points of chemical units. According to the teacher's arrangement, we did special training on centrifugal pump unit in the first two days, and concentrated on fixed bed reactor unit in the last two days, followed by batch reactor reaction unit, rectification unit and absorption analysis unit. According to the implementation of this plan, I have gained a lot of experience, of course, there are also good aspects and shortcomings, and I have made a summary of these experiences.

Because we are learning the unit of chemical engineering principles, plus the previous experimental links, I have a general understanding of its principles and instruments and equipment in the textbook, so some of its terms are not unfamiliar and go smoothly. In the simulation experiment, except for some software necessary processes, other experimental operations made me deeply understand the use of interlocking and cascade in real experimental operations. Then I checked whether the pressure gauge reached the required pressure, and then I adjusted the pressure reducing valve. Then adjust the gas flow; Turn on the main switch of the main engine and adjust it in the temperature controller according to the experimental requirements; In addition, the temperature adjustment of batch reactor unit is very important. The temperature is controlled between 1 10~ 120, so we need to operate according to the provisions in the step. We can learn some experience from it after mastering the operation, but the order of the steps cannot be reversed. In terms of knowledge points, it is much easier and more profound to learn through such learning than simply memorizing the knowledge in textbooks, and it is also more impressive to consolidate the knowledge learned.

Because simulation is a new thing for us, we don't know much about instruments or knowledge points because we haven't been exposed to it before. Fortunately, I took a general look after class before the training could continue. In computer operation, after selecting the unit to be done, I find out the operation steps of the unit, and then I am familiar with the flow of this unit, and then I make a comprehensive analysis of the principle, steps, flow chart, field diagram and dcs diagram. Finally, I will have a simulation exercise. After this simulation training, I have a certain understanding of its related instruments, not just imagination. This is more conducive to my future operation of instruments in practical work, and to upgrade my corresponding skills and knowledge to a new level.

Of course, there are still many shortcomings in this training, and many specific operational links have not been clarified, because the corresponding steps can be scored as long as they are done, and there is no further investigation. This practice of muddling along will be corrected in the future.

For simulation training, it is a good thing, which can make students better understand the relevant knowledge and understand the operation of related instruments; Of course, it would be better if we could do experiments on real instruments by ourselves. However, the simulation environment also has some shortcomings, so students should be given some free time during the training process, otherwise they will easily get tired.

I am deeply grateful to all the teachers who have been accompanying us in the simulation training. When you were busy, you took the trouble to accompany us through these tense fifteen days, and urged us from time to time, so that we didn't waste these fifteen days and really learned a lot of knowledge. So, thank you teachers.

The above is my experience after passing the 15-day simulation training. I hope to continue to carry forward the advantages and resolutely correct the shortcomings in the future.

Experience of Simulation Training (2)

With the emergence of a large number of high-rise and super-high-rise buildings, how to reduce the operating costs of buildings, improve economic benefits, and achieve open source and throttling has become a subject that property management companies must face. As we all know, in the operating cost of a building, the electricity expenditure of construction equipment accounts for a considerable proportion. Electricity price is closely related to the related design and operation management level of buildings.

China's current electricity price structure is still composed of basic electricity fee and metering electricity fee. Usually, the electricity expenditure of office commercial buildings is calculated by the power supply department according to the demand electricity fee of each transformer (according to the total capacity of the transformer) plus the metering electricity fee. Property management companies usually calculate public facilities by office space and share the electricity charges of central air conditioning, elevators, lighting and other equipment. The different inputs of transformers and their utilization rate will directly affect the unit price level of electricity charges, resulting in an imbalance between revenue and expenditure of electricity charges. Therefore, by improving the utilization ratio of the transformer and reducing the input of the transformer under the same power load, the basic electricity cost and loss of the transformer will be reduced. However, the designers of buildings often ignore the economy of equipment operation and can't fully consider the influence of seasonality of equipment operation and the utilization rate of buildings on electricity demand. Therefore, the design of power supply and distribution equipment in many buildings often has the phenomenon of large horse-drawn carts, which leads to the increase of operating costs.

Times Square is the first intelligent building fully put into use in Shenzhen. There are 38 floors above ground and 3 floors underground, with a building area of 87000m2. The total capacity of power load is 7500kVA, which consists of 6 transformers 1250 kva. After the building is put into use, the electricity consumption fluctuates greatly due to the rental utilization rate and climate and temperature changes, and the number of transformers is usually 1 ~ 4. However, due to the structural design of the power system, the system must start three transformers at the same time to ensure normal operation. The average utilization rate of each transformer is often less than 30%, resulting in the basic electricity cost and loss of 1 ~ 2 transformers. According to the electricity price charging standard in this area, the annual waste alone is as high as one million yuan.

1 General situation and existing problems of power supply and distribution system in the building

Based on the higher requirements of high-rise buildings for the safety and reliability of power supply, it is usually designed according to the first-class load standard: that is, high-voltage 10kV dual power supplies are used in sections for mutual backup, as shown in figure 1 (solid line part). Six low-voltage transformers are operated in three sections, and each transformer is a group, which is powered by different high-voltage 10kV power supplies. Standby each other through contact switches; Interlocking among three switch cabinets can prevent transformers from running in parallel, and avoid safety accidents such as short circuit of 10kV high-voltage system or reverse power supply to 10kV high-voltage system power grid. General situation of system load distribution: 1# and 2# transformers supply power for office and lighting of the building; 3# and 4# transformers supply power for four refrigeration units and other power sources; 5# and 6# transformers supply power for elevators, water supply and drainage and other power. Because the dual power supplies are mutual backup, the reliability of power supply is improved to some extent. However, because the six transformers operate in three sections, at least three transformers need to be put into operation at the same time to meet the load power consumption of the whole system, which is difficult to meet the demand of reasonably adjusting the number of voltage restorers in different seasons and rental areas with different temperatures. Key points of technical transformation of building power supply and distribution system

It is not difficult to see from the diagram of the primary loop system of the building (as shown in figure 1) that the above problems can be solved as long as two connecting cabinets are added at the subsection points of the system. Six transformers are switched on and off reasonably according to the actual electricity consumption through the opening and closing of five wiring cabinets, and run in sections with the input of transformers to supply power for the whole low-voltage system load. The technical difficulty of this scheme lies in how to solve the interlocking of multiple switches and prevent the short circuit or reverse power supply safety accident of the above high voltage system caused by the parallel operation of transformers.

Three-switch interlock is extended to five-switch interlock, which realizes multi-combination operation of multiple transformers. It is concluded from Figure 1 that no matter how many transformers the system consists of, as long as any switch cabinet can interlock with adjacent switches, the interlocking requirements of the whole system can be met.

(1) As shown in Figure 2, the main switch of any transformer (such as A3) only needs to be interlocked with two adjacent contact switches Q2 and Q3 in the secondary circuit of the main switch of the transformer, so that the interlocking of three switches can be realized. That is, the precondition for A3 to close is that the interlocking normally closed contacts of Q2 and Q3 are in the closed state, that is, when the two switches are in the off position, the closing coil YC of A3 is energized and the closing mechanism operates. After A3 is closed, the operating procedures of Q2 and Q3 are executed according to the following control principle of contact switch, and other switches can be in any state;

(2) As shown in Figure 3, any contact switch (such as Q2) only needs to be interlocked with two adjacent contact switches Q 1 and Q3 and two adjacent transformer main switches A2 and A3 in the secondary circuit of the contact cabinet switch, so that five switches can be interlocked. That is to say, the prerequisite for Q2' s closing is that the normally closed contacts of Q 1 and A2 or Q3 and A3 are in the closed state, that is, when Q 1 and A2 or Q3 and A3 are in the open position, the closing coil YC of Q2 is energized and the closing mechanism operates. After Q2 is closed, Q 1, A2, Q3 and A3 operate according to the corresponding switch control principle, and other switches are in any state. This can ensure the interlocking of 1 1 switches or even infinite switches, and the transformers can be put into operation according to the actual electricity consumption: one transformer is put into operation, and the whole section is powered, and the main switches of other transformers are in the off-switch position due to interlocking; When the two transformers are put into operation, they are operated in two sections, and the main switches of other transformers and the interlocking switches of each section are in a disconnected state due to interlocking. By analogy, any number of transformers can meet the interlocking requirements of the system. It ensures the economy of system operation. At the same time, the reliability of power supply is greatly improved because of the importance of transformer combination operation mode.

3 component selection and its working principle analysis and explanation

The system adopts world famous brand ABB series switches, with complete protection functions, high degree of automation and reliable performance.

(1) The interlock contacts of the above switches are all linked by the contacts of the switch body, and no misoperation will occur;

(2) All switches are electric under normal conditions. It is not difficult to see from Figure 2 and Figure 3 that the main switch operation power supply of the transformer is taken from the incoming end of the switch, and the contact switch operation power supply is taken from any end of the switch, both of which are equipped with voltage-loss tripping devices, which further ensures that all switches are in the off state when power is cut off and avoids the misoperation of the switches;

(3) The driving mechanisms of all switches (such as closing, YO shunt excitation and YU voltage loss) are driven by instantaneous power supply, so the failure rate is low. For a more detailed principle of the switch actuator, please refer to the relevant product manual.

Experience of Simulation Training (3)

The training in the past two years has been perfunctory. The teachers hurried into the classroom, told us to practice quickly, arranged the questions in a hurry and handed them in two weeks later, and then left the classroom in a hurry ... so I don't know what the college training is about. In my impression, training is to write a report and hand it in every half month, as simple as that. 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 certainly 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 parts we don't have. Then we are giving full play to the role of "screws". 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 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 understanding, 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 various learning achievements.
