Distribution System Reliability Assessment Software Based On Bayesian Network And Sequence Simulation

Distribution system is a grid in the power system and the large electric powercustomer directly connected part, its reliability directly affects the degree of users ofuninterrupted power supply. With the rapid development of national economy, power usersincreasingly high demands on power supply and. Therefore, has the vital significance toprovide the reliability of distribution system. The reliability evaluation of distributionsystem is based on planning and operation process, and the reliability of power supplydistribution system, reliability index model of distribution system reliability evaluation ofreasonable and accurate, convenient, fast is required, this paper intends to develop asuitable for any reliability evaluation of complex distribution system software.Based on the analysis of existing evaluation methods, a new method to evaluatereliability of distribution system based on Bayesian network timing simulation. Thismethod can be very good to make up for the shortcomings of the traditional method,reliability evaluation can not only carry out distribution system, can also identify the weaklinks of the system. First of all, the overall functions and interface of the software isdesigned, built a close relationship database platform and development, can be convenient,fast and high data transmission between the interface and database. Secondly, we constructa Bayesian network for distribution system and timing simulation inference algorithm isdesigned in detail, which can automatically generate a Bayesian network to describe thedatabase form, and automatically calculate the reliability index of distribution system.This paper takes.NET Framework as the development platform, Microsoft Visual C#is the programming language, Microsoft Access2000as the database, software reliabilityevaluation of distribution system develops the general version, this software has stronguniversality, friendly interface, flexible operation, and by using the object-oriented designand object-oriented language, makes the the software is easy to maintain and extend.Finally, the IEEE test system RBTS bus2F1, F2feeder is used as an example, the resultsshow that the software is correct and effective.
