Problems solved by technology

[0005] However, under the current situation, most of the thyristor-controlled reactor controllers used in domestic thyristor-controlled reactor + FC projects are imported equipment. For example, although the SIMADYND control system of Siemens has high reliability, the price is as high as More than 1 million yuan is not acceptable to domestic project users, and the domestic research and development of this technology is in its infancy, and no molding technology has yet appeared. Therefore, it is necessary to develop a high-reliability thyristor-controlled reactor controller. necessary

Description

technical field [0001] The invention relates to a controller for a thyristor-controlled reactor circuit, in particular to a controller for a thyristor-controlled reactor used in the management of a medium-voltage power grid. Background technique [0002] Static var compensator - SVC (Static Var Compensator) for short has been widely used in reactive power compensation and harmonic filtering of loads, and its typical representative is fixed capacitor bank + thyristor control reactor - FC + thyristor control reactor (Fixed Capacitor+Thyristor Controlled Reactor) type. The important feature of the thyristor-controlled reactor is that it can continuously adjust the reactive power of the compensation device. This continuous adjustment is achieved by adjusting the firing angle α of the thyristor of the thyristor-controlled reactor. Since the adjustment is continuous and responds quickly, Therefore, the SVC can dynamically compensate the reactive power, so that the voltage at the ...
