Study And Design Of General Plan Of Power Distribution Automation For LinDian County District

Distribution automation is the inexorable trend of the modern development of power system. At present, trough the power system of LinDian county has been large-scale constructed consist of building or upgrading power grids, the layout of distribution network can be more rational, the safety and reliability of the equipments also can be ensured. And recently the power system technology of LinDian county has been improved greatly. So the design of distribution automation system on information technology in LinDian county has important meanings, and it can be used widely.Combined with the practical situation of distribution network of LinDian county district, start with the present state of electric network of LinDian county district, trough the theoretical and contrast analysis on several problems of city distribution automation, the study finishes the integral design scheme of LinDian county district distribution automation system, which contains based on comparative analysis some feeder automation and combine the actual state of LinDian we proposed two realistic solutions "hand in hand" circular distribution network feeder automation; After detailed analysis the characteristic of LinDian distribution network and DNP communication protocol we using C# to realize the Communication Service Program , based on the structural design of main station carry out its'software and hardware configure etc. The direction idea is that, technology is advanced, performance is reliable, distribution combined with concentration, open combined with integration, maintenance is simple, operation is convenient etc.After running and Economic benefits analysis, county district distribution network employs the automation system, Which improves the reliability and quality of the current supply, reduce the loss, improve the integral control level, realize management modernization. And it can assure safe, reliable and economic current supply, so it has some economic benefits and indirect social benefits, so it should be popularized.
