Research on the Self-healing Control Model of an Urban Intelligent Distribution Network with Distributed Energy Sources
The self-healing control model of an urban intelligent distribution network with distribted energy sources is studied.Take 35kV substation distribution network as the power-supply centre,leading incoming feeders from dif-ferent class power points.Lead out a certain 10kV feeders under the power points and set up communication among different circuits.According to the distributed power supply output characteristic,carry out wind velocity fitting,get-ting relations between wind velocity and power.By automatic cutting off capacity,reducing emergency control objec-tive.According to load demand,control the voltage value at the hoth ends of the node in order to restrain capacity addition to the circuits.Use ant swarm algorithm to carry out the network reconsitution,look for superiority of recov-ery strategy after faults.Look for load of the main network recovery to carry out recovery power supply,thus finishing the self healing control.The test result shows that when faults happens in the distributed network,all the protection time is less than 150ms,the self healing time less than 70ms,the results are in conformity with the desired results,which can support protection distribution network running,achieving better application.
