Real-Time System Of Distribution Network Economic Operation

With gradual deepening of power industry reform and the power station separation from power network, Each power supply bureau strives to reduce the loss of power network operation on the basis of security of the power system in order to make the best economic benefits. Distribution network reconfiguration is one of the effective measure that reduce the loss of operation of power network. At present, the distribution network reconfiguration is operated according to season mainly, but the load changes at any time and it is not obvious that the reconfiguration reduces the loss. So, study the real-time distribution network reconfiguration has the realistic meaning with importance. But the present distribution network reconfiguration algorithm aims at the distribution network of the same grade voltage and it scarcely involves the distribution network reconfiguration of many grades voltage. According with this situation and the project actual demand, the thesis has put forward the software and hardware conceptual design of the distribution network economic operation real-time system and many grades voltage distribution network reconfiguration algorithm. The actual operation result has verified the validity and exactness of this system scheme and the algorithm.The main content of the thesis has: To the project actual demand , this thesis has put forward the software and hardware conceptual design of the distribution network economic operation real-time system, and has introduced the software and hardware structural design among them in detail .On the basis of improving the branch exchange Method , this thesis has put forward distribution network reconfiguration algorithm of many grades voltage, and has solved the actual demand of the project effectively.One of the foundations of the distribution network economic operation real-time system is the topological analysis of the network. The thesis has proposed topological approach of distribution network by layer, and this approach has reduced the network size greatly and improved the speed of topological analysis.This thesis has designed the backstage software of the distribution network economic operation real-time system. And this software has been put into practical application.
