Adaptive HVDC Circuit Breaker Based on Capacitor Voltage Regulation Principle
HVDC circuit breaker which can be able to interrupt high current is one of the important factors affecting HVDC power transmission. A kind of design scheme of adaptive HVDC circuit breaker(HVDCCB)based on capacitor voltage regulation principle is proposed. The reversal of arc current is achieved by shunt voltage regulation capacitor so to form multiple current zero point
limit the arc current near the current zero point for a certain amount of times so to create good condition of arc interruption. Both theoretical derivation and simulation results show that the proposed HVDC CB scheme can adapt to various of operation conditions
avoid the conduction losses of power electronic devices
reduce the probability of arc reignition and improve fast breaking capability of the HVDCCB effectively.
