Construction of Protection and Control System for Active Distribution Network
This paper discusses the construction of protection and control system for active distribution network.The structure of protection and control system of active distribution network consists of three layers: the centralized monitoring layer, the optical fiber network layer and the terminal nodes layer.According to the operation mode of distributed power supplies, the real-time energy dispatch strategy of active distribution network is set to maintain the normal operation and maximize the use of renewable energy.A new multi-level protection system with centralized differential protection as main protection, multi-stage over-current protection and distributed power body protection as backup protection is set to isolate fault point quickly and reduce the power failure scope.
