An Integrated Protection of Micro-Grids Based on Bi-Directional Blocking Principle

Abstract:

Reliable and accurate microgrid protection is significant for micro-grid operation.traditional proection methods can not meet the requirements of microgrid.this paper discusses the problems of the existing micro-grid protection methods. Then proposed a new microgrid protection scheme which uses integrated protection as the main protection of microgrid. this protection scheme is based on bi-directional blocking principle,which will send blocking signal if there is no fault .thus protects microgrid. The proposed method is proved to be an effective method for microgrid.
