Rationally Designing Relaying Protection Scheme for Power System Black-Start
Power system black-start is a very important choice after system black out.Due to the great difference be-tween normal operation and black-start,the fault current should be calculated again in the process of designing pro-tection scheme for system black-start.This paper discusses the method to make protection scheme for system black-start with the case of the first black-start test of Hubei power system.
