Abstract:
The voltage compensator is composed of following parts: for charging module of superconducting energy storage, charging module is composed of a rectification bridge in three phase, a filter and a electronic switch; connected to DC side of charging module and inversion module in parallel and in use for storing electrical energy in DC form, the module of superconducting energy storage consists of a superconducting coil, a electronic switch, a power diode and a capacitance; in use for outputting offset voltage, the inversion unit includes inversion bridge in three phase; in use for connecting dynamic voltage compensator to power system, the isolation filtering unit includes three pieces of isolating transformer and three capacitors. The disclosed dynamic voltage compensator meets the need for compensating voltage fall off at short time in power system. Comparing with prior art, the disclosed dynamic voltage compensator possesses better dynamic response and longer compensating time.
