Feeder Automation System In The Implementation Of The Power Supply Reliability Demonstration Zone And Promotion Prospects

Distribution Automation (Feeder Automation, hereinafter referred to as FA) or calledfeeder automation is the use of automated systems or devices, monitor distributionnetwork operation of transmission lines, distribution network to quickly detect the faultlines in a timely manner and to determine the fault line fault line isolated, immediateresumption of non-fault power supply range of users.Distribution Automation is able to electrical power distribution equipment for remoteoperation of the online real-time monitoring, command and control of an integratedsystem is the distribution grid in recent years developed a new technology and a newdirection of development of modern communication technology and computer real-timemonitoring technology in the power distribution grid on the application. Japan and Europeand other industrialized countries are vigorously promoting the technology, the domesticpart of the power grid distribution automation companies are also areas of thecorresponding research work. Distribution automation can greatly improve the efficiencyof distribution grid operation and reliability, improve power quality, reduce the laborintensity of grid operation, make full use of existing network equipment supply capacity.Therefore, distribution automation and electric grid company for business users are able tobring a win-win situation.The safe operation of power distribution grid problem has not been long enoughattention to power supply companies, distribution network automation level is far behindthe development of substation automation. With the power distribution grid structure andcomposition of the increasingly complex systems, power distribution grid ground fault,phase failure, especially various types of distribution cable failure becomes very difficultto correctly judge; failure occurred, how to eliminate the use of automatic safety devicesfailures, lack of research; action information in the protection and switching information isincomplete, or even refuse to move, malfunction or misuse of the case, how does thestructure of the distribution grid complex fault section, research in this area has yet to be applied to further our strengthen.Shanghai Electric Power Company to establish high reliability demonstration areacontains a core function of an international financial center Lujiazui area along theYangtze River, including the Huangpu River, is designed to improve grid reliability,providing management and technical aspects of experience, as well as Shanghai Pudonggrid grid construction provides high reliability demonstration. Distribution Automationdemonstration area in high reliability applications can be implemented with a smallerinvestment and strive to achieve reduced power range, reduce outage time, reduce powerloss and improve the reliability of power supply.In this paper, the principle of distribution automation, communications programs, andshould be distributed first domestic distribution automation in2010Shanghai World ExpoPark in Pudong and Pudong high-reliability power supply company demonstration zonefor the implementation of such introduction, while this system Pudong distributionnetwork throughout the promotion prospect. Previous diagnosis function due to neglect ofthe back-up protection objectives and the main protection of the relationship between thestate and the absence of a model with the impact of the diagnosis is not the only issue,therefore, targeted to the objective function is optimized and correction. Study presents acombination of techniques based on artificial intelligence distribution network faultdiagnosis method.
