On September 19, with the successful passing of the 100% load rejection test under generating mode for the last unit (Unit 1), the dynamic commissioning of the final unit at Wuyue Pumped Storage Power Station was successfully concluded.

Since the startup acceptance committee meeting for Unit 1 was held on August 29, the test team of the Sinohydro Bureau 4 project promptly deployed various commissioning tasks. Through a series of measures including scientific coordination of resource allocation, reasonable scheduling, and strict process control, after the first startup under turbine mode on August 30, they successively carried out various dynamic commissioning tasks such as unit thermal stability, overspeed, voltage rise, current rise, main transformer impact, grid connection, startup under pump mode, and mode conversion. All commissioning items were successfully completed on the first attempt, with all technical indicators superior to design values and stable and reliable operation, fully verifying the excellent level of unit design, manufacturing, and installation quality.

The Henan Wuyue Pumped Storage Power Station is equipped with four pump-turbine generator-motor units, each with a unit capacity of 250,000 kilowatts, and a total installed capacity of 1 million kilowatts. Sinohydro Bureau 4 undertook the installation and commissioning construction tasks for the four units and their auxiliary equipment, as well as part of the civil construction tasks. After the power station is fully put into operation, it will mainly undertake tasks such as peak shaving, valley filling, frequency regulation, phase regulation, and emergency accident reserve for the Henan power grid. It can save 116,800 tons of thermal power coal consumption per year, equivalent to reducing carbon dioxide emissions by about 291,400 tons, sulfur dioxide by about 8,800 tons, and nitrogen oxides by about 4,400 tons annually, with significant economic and ecological environmental benefits.
Next, the project department will efficiently advance the grid-related testing of Unit 1 and accelerate the completion of the unit's commissioning and power generation goals on schedule.
