CONTROL SYSTEM FOR STATIC THYRISTORIZED COMPENSATOR Russian patent published in 1994 - IPC

FIELD: electric technique, electric power supply systems. SUBSTANCE: static thyristorized compensator control system having a phase-wise control system to first inputs of which outputs of a regulator are connected and outputs of which are connected to control terminals of thyristorized units of the static compensator is provided with six voltage dividers interconnected between the terminals of thyristorized units and ground, with three comparison devices and a reference voltage device so as to provide a forced switching-on of the thyristors at the moment of occurrence of hazardous overvoltages at the outputs of thyristorized unit. EFFECT: reduced number of thyristors connected in series, reduced cost. 5 dwg
