Abstract

At present

the flexible HVDC system cannot realize DC side short circuit fault clearing

it leads to chronic failure of all converters. To solve this problem and improve the reliability of the system

this paper researches the mechanism of fault current

the principle of DC interruption and simulates the influence of transfer parameters on DC breaking performance;proposes a mechanical DC circuit breaker of 500 A and a method of clearing the DC fault using the DC circuit breaker. Finally

building a low frequency oscillation circuit verifies the interruption performance of the breaker. The results show that the breaker stably breaks 500 A. The method can effectively shorten the system recovery time

improve the stability of the system and ensure the quality of electric energy.
