How many mw can a 400 MW variable-speed unit change?

It can achieve high-speed adjustment of active power. The 400-MW variable-speed unit can change the output power by 32 MW or input power by 80 MW within 0.2 s.

What is a fixed-speed pumped-storage power station?

The fixed-speed pumped-storage power station has a step-type output. Take one of pumped storage power stations as an example. It takes only about 16 s from −50 MW to −300 MW, and just 14 s from −300 MW to 0 MW. It means a 300 MW unit trips several times in one day, which has a great impact on the Fujian province power grid.

What are the advantages of pumped storage-power stations?

The power response speed of the new pumped- storage station can reach the millisecond level, which greatly enhances the safety, reliability, and comprehensive adjustment capability of original large-scale pumped storage-power stations. Both sunlight and water resources are green and clean energy.

What are the characteristics of pumped-storage power stations?

Through the characteristics analysis of the new type of pumped-storage power station, three types of optimal station locations are proposed, namely, the load concentration area, new energy concentration area, and ultra- high-voltage direct current receiver area.
