Reporters learned from the Provincial Energy Bureau that recently, two 400 MVA oil-immersed transformers supporting the key energy project in the province - XX Pumped Storage Power Station - were successfully commissioned, marking that the power station has entered the full grid-connected power generation preparation stage. These two transformers are custom-produced by local enterprises and will undertake the core tasks of boosting and transmitting electric energy of the power station to ensure stable power access to the provincial power grid.

It is reported that XX Pumped Storage Power Station is a key planning project of the National Energy Administration, with a total installed capacity of 1.2 million kilowatts. After commissioning, the annual power generation can reach 1.8 billion kilowatt-hours, which will effectively alleviate the pressure of regional new energy consumption and improve the peak shaving and valley filling capacity of the power grid. To meet the high-load and high-reliability operation requirements of the power station, the customized oil-immersed transformers adopt advanced technologies such as enhanced short-circuit resistance design and intelligent online monitoring, which can real-time monitor key parameters such as oil temperature, oil level and insulation status to ensure the safe and stable operation of the equipment.

The person in charge of the project constructor said that to ensure the smooth commissioning of the transformers, the construction team formulated a detailed plan in advance, overcoming many challenges such as difficult transportation, high installation precision requirements and complex cross-operation, and completed all work including hoisting and commissioning of the transformers within one month. Next, the team will continue to promote the construction of subsequent supporting projects of the power station to ensure that the power station will be fully grid-connected for power generation as soon as possible.
