recently, the project department of Shenzhen pumped storage power station of south grid energy storage operation company successfully completed the black start test of unit 1 and unit 3 of the power station.
during the black start test, the operation personnel of the deep storage project department of the south grid energy storage operation company are carrying out the test operation.
According to weather forecasts, Shenzhen will encounter strong convection and heavy rainfall around the Qingming Festival. On the day of the test on April 4, there was a sudden heavy rain in the deep storage power station area, and the power station issued a yellow warning for typhoon prevention and flood prevention. This test is the first black start test of the deep storage power station under severe weather conditions, which further verifies the black start performance of Unit 1 and Unit 3 of the deep storage power station in extreme scenarios, and tests the emergency response capability of the operators. The success of the test ensures that the power station units can be “opened, adjusted, and stopped”, which provides a strong guarantee for the safe and stable operation of the power grid.
During the black start test, the deep storage power station area encountered heavy rainfall, and the duty personnel of the deep storage project department of China Southern Network Energy Storage Operation Company were carrying out outdoor operations.
in the face of severe weather conditions of heavy rainfall, in order to ensure the safety of the test, the test group of the deep storage power station project department of the south network energy storage operation company made accident anticipation in advance and built perfect rain-proof facilities in the outdoor switchgear area. The test personnel maintained high efficiency and order. The black start test of Unit 1 and Unit 3 was successful once, and the 220kV line with black start of Unit 1 was charged normally. In the test, it took only 2 minutes and 53 seconds for the diesel generator to start to fully recover the auxiliary power system, only 2 minutes and 10 seconds for the unit to start from black to isolated network operation, and the auxiliary equipment successfully completed three power switches during the operation of the unit. The complete success of the test fully reflects the high reliability, fast response and excellent performance of the black start function of the deep storage power station unit.
it is reported that since the deep storage power station was put into full operation, it has successfully completed the black start test of four units, becoming the first pumping storage power station of south grid energy storage company to complete the black start test of all units, providing a strong local guarantee power supply for Shenzhen’s strong local power grid. The deep storage power station will continue to play its role as an important power source for a strong local power grid, providing more reliable power guarantee for Shenzhen and surrounding areas, and helping the safe and stable operation of the Southern Power Grid.
