At 15:37 on June 29th, Henan Power Grid Tongyuhekou Unit 2 was operated by the camera mode for the first time, marking the successful completion of the first domestic thermal power crew to increase the phase -regulating function transformation demonstration project.

Henan Power Grid Tongyuhekou No. 2 unit is located in the near area of ​​1,000 kV high -voltage Nanyang Station. The installed capacity is 350,000 kilowatts. It was launched in 1999 and is currently an emergency spare unit. In 2019, with the unified promotion of the State Grid Henan Province Electricity Company, the Yahekou Power Plant began preparations and preparations for reconstruction, and officially launched Unit 2 of the Unit 2 on April 27 this year.

In order to promote the increase in the function of thermal power crew, the State Grid Henan Electric Power led the organization of power generation enterprises, motor manufacturers and design institutes according to the characteristics of the power grid characteristics, and took the lead in completing the research feasibility study of the function transformation technology transformation technology in the country. It also coordinated the government to issue relevant support documents, encouraging the provincial units in the province to increase the transformation of phase modulation function, clarify the compensation mechanism, and lay the policy foundation for the implementation of the transformation. At the same time, the formulation of the network involved test regulations and the management regulations of the grid operation after the formulation of the function of thermal power unit increased function is formulated, which laid the technical foundation for the connection operation after the transformation.

Increasing the function transformation of thermal power crew can achieve a win -win situation in the grid side, power supply side and the whole society. After the transformation, the Division No. 2 of Yahekou can flexibly select the generator mode or the camera mode to operate according to the needs of the system. Use shutdown or retired units to increase the utilization of equipment to explore new directions for the sustainable development of thermal power. In addition, compared with the newly -built camera, thermal power crew increases the cost of modified function renovation, which is more cost -effective, and can further save the production cost of the whole society.

In the next step, the State Grid Henan Electric Power will continuously optimize the operation method of the grid, actively cooperate with the DVAV of Yahekou to conduct network -related tests, urge it to try the 168 -hour trial operation through the camera mode as soon as possible, and transfer to the generator mode Du Xiabao power supply provides strong support.
