【 摘 要 】

Because the head of the traditional adjustable-speed pumped-storage system is relatively fixed during power regulation, the adjustable-speed pumped-storage system based on virtual head technology is proposed in this paper. Through the introduction of each device, the principle and the implementation method of virtual head technology and variable speed technology are analyzed.Aiming at the output characteristics of adjustable-speed pumped-storage generator-motor under different modes, the loud optimization process characteristics under pump and turbine running conditions is established respectively.
