Application and Optimization of DC System Protective Device Stage Difference Coordination Test

XIA Ming-sheng;China Datang Corporation Science and Technology Research Institute Co.,Ltd.Eastern China Branch;  
As an important part of the power system,DC system is the basis of modern automatic control and monitoring.In recent years,specific requirements for stage difference coordination in DC circuit breakers and fuses protection have been put forward in both the power industry standard and anti-accident measures.This paper introduces the current development and mainstream test methods of DC system protective device stage difference coordination.In accordance with practical experience,it summarizes part of the shortages of ″small internal resistance short-circuit current prediction method with short circuit simulation verification method″ and proposes the optimization and improvement of the test methods.
