Decision Support System For Distribution Automation

With the high-speed development of economy and science technology, the demand of industry and resident for power supply quality is higher and higher. It is more and more important to improving power supply quality and reducing the time of power cut. Distribution automation comprehends modern electricity technology, communication technology, internet technology and electric power equipment. With the growth of the computer technology, it is practical to establish distribution automation system which is better and more intelligent. Based on the technique of Visual C++ and Database, the paper design the Decision and Support System used for trouble location and reconfiguration of the network.The structure of SQL database and data dictionary is designed in detail. In system development, the work is carried out in order. At first, distribute the network topology based on the graph theory and get the network topology through algorithm. Then, with the analysis and research of the complex example, decide the trouble location of the example using matrix algorithm, improved matrix algorithm, Genetic Algorithms and BP neural network algorithm. Through the emulation by the MATLAB, analyze the reliability, real time and practicability of the algorithms. Next, after analyzing the trouble location, with the load of distribution, decide the reconfiguration through the expert system. At last, distribute the network after reconfiguration topology. Based on the analysis of Decision and Support System for Distribution Automation, the paper presents improvement against the limitation of existing system. The innovation of the system consists in distribution of the network topology based on the graph theory, decision the trouble location using improved matrix algorithm and the reconfiguration decision-making based on the expert system. It can be consulted and popularized by homogeneous system.
