GEAR FOR CONTROL OVER VOLTAGE OF ASYNCHRONOUS AND SYNCHRONOUS GENERATORS Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: gear for control over voltage is designed for unit-type electric power station fitted both with synchronous and asynchronous generators. Control over of synchronous and asynchronous generators is performed be means of regulation of transformation ratio of transformer of asynchronous generator and of excitation current of synchronous generator depending on excess of voltage of asynchronous generator within specified limits of change. For this purpose device is provided with automatic controller of transformation ratio, logic OR and NOT gates and controlled key. EFFECT: increased efficiency of control. 2 dwg
