Switching Capabilities of the Units of Pumped Storage Hydroelectric Power Stations with Asynchronized Synchronous Motor Generators

The conditions of power control of the hydraulic generating units of pumped-storage hydroelectric power stations with the use of the capabilities of asynchronized synchronous motor generators are considered. Characteristics that relate the size of the permissible surge in load in emergency control with limitations on the permissible deviation of the rotational speed of the hydroelectric generating units are obtained.
