Method for operating a pumped storage power plant

摘要

A method for operating a pumped storage power plant, comprising an upper water basin, an underwater pool, a waterway, which is arranged connecting between the upper water basin and the underwater pool, arranged in the waterway reversible pump turbine, a synchronous machine, a transformer, via which the synchronous machine is connected to a transmission network, a start-up converter and a power controller for controlling the pumped-storage power plant, the method comprising the step of: V1: determining the operating mode of the starting converter by the power controller; and the method comprises the following operating modes of the starting converter: V2: accelerating the pumping turbine through the starting converter; Wherein the pumped storage power plant comprises a memory for electrical energy, which is arranged in the direct current intermediate circuit of the Anfahrumrichters, and the method comprises the following further operating mode of the Anfahrumrichters: V4: Provision of control power by the starting inverter for power frequency stabilization.
