How to work at the Electric Power Bureau?

1. Power grid enterprises

1. Company establishment

The State Grid Corporation of China was established on December 29, 2002. It is a state-authorized investment approved by the State Council. institutions and pilot units of state-controlled companies. The company ranked 24th on the Fortune Global 500 in 2008 and is the world's largest utility company.

China Southern Power Grid Co., Ltd. was officially established and started operations on June 18, 2004. The company's business scope covers the five provinces (regions) of Guangdong, Guangxi, Yunnan, Guizhou and Hainan. It is responsible for investing, constructing and operating the southern regional power grid, operating related power transmission and distribution businesses, and participating in the investment, construction and operation of related cross-regional transmission and transformation. Electricity and Internet projects; engaged in the purchase and sale of electricity, responsible for power trading and dispatching; engaged in domestic and foreign investment and financing; independently carried out foreign trade circulation operations, international cooperation, foreign project contracting and foreign labor cooperation and other businesses.

2. China Southern Power Grid

According to the "Electric Power System Reform Plan" of the State Council, China Southern Power Grid Corporation was officially established and began operations on December 29, 2002. The company is under central management, and the State-owned Assets Supervision and Administration Commission of the State Council performs the investor's duties. The company's business scope covers Guangdong, Guangxi, Yunnan, Guizhou and Hainan. It is responsible for investing, constructing and operating the southern regional power grid, operating related power transmission and distribution businesses, and participating in the investment, construction and operation of related cross-regional power transmission and networking projects; Engaged in the power purchase and sales business, responsible for power trading and dispatching; engaged in domestic and foreign investment and financing business; independently carried out foreign trade circulation operations, international cooperation, foreign project contracting and foreign labor cooperation and other businesses.

2. Hazardous Editing and Reporting

1. The normal operation of the power grid frequency stipulates that the fluctuation shall not exceed ±0.2Hz.

2. Regulations issued by the Ministry of Electric Power Industry of China stipulate:

3. The operating time with a frequency lower than 49.5Hz cannot exceed 60 minutes.

4. The operating time when the frequency is lower than 49.0Hz cannot exceed 30 minutes.

5. The normal operation of the power grid frequency stipulates that the fluctuation shall not exceed ±0.2Hz.

6. Because it not only affects the internal operation of the power system, but also affects thousands of households to varying degrees. When the frequency drops to 48Hz, the motor speed drops by about 4, so the output of many industrial products will drop and the quality cannot be guaranteed. Therefore, it is very important to ensure that the power system operates stably at the rated frequency.

3. Operation Arrangement

1. The primary arrangement of electrical equipment. The primary arrangement of electrical equipment in the power grid is based on the operation of the electrical equipment in the generator grid. The arrangement includes generators, lines/transformers . Maintenance of busbar switches and other equipment. It also includes the commissioning of various new equipment. The normal operation of these power grids will have a certain impact on the security and stability of the power grid.

2. Stability calculation and analysis. In view of changes in the primary mode of power grid electrical equipment, grid regulator operators need to perform stability calculation and analysis of the power grid control section. Usually this control section includes thermal stability and transient stability. In this aspect, the seriousness of the two is used as the power flow limit of the stable control section system, so that the power grid dispatching operators can control the power flow distribution of the power grid.

3. Bus load prediction. The bus load prediction function is to predict future power load based on historical power load conditions. Usually ultra-short-term load forecasting and short-term load forecasting have higher accuracy. Therefore, the load forecast used in this article is usually the load forecast value at 96 o'clock tomorrow or the short-term contribution load forecast within one stroke. These bus load forecast values ??are used as basic data for power generation safety check and power supply capacity assessment. .

4. Power generation plan arrangement. The power generation plan is carried out according to the power generation contract signed between the power generation enterprise and the power grid company and the power grid operation mode. Ensure power balance and ensure reliable power supply to users.
