摘要
Abstract
In view of the low voltage dc power distribution network , this paper proposes a protection scheme by using the self turnoff function of the VSC instead of DC current -limiting circuit breakers .This paper focuses on fault inter-ruption and isolation , uses relays to detect the quantities of the protected area and send action signals to the converter , then the converter isolates faults .Establishing a simple two -terminal DC power distribution system model in the PSCAD, it is shown that overcurrent -based schemes can be adopted for these relays to meet the fast response require-ments, laying a good foundation for the next step research of Dc power distribution system protection scheme .关键词
