| Distribution automation is an important way to improve distribution management and thereliability of power supply, the developed countries such as the united states and Japan areusing this technology on a large scale, some domestic cities also begins this application. Withthe development of economy and the power supply in Huiyang district, it requests higherrequirement on reliability of power supply、customer service, distribution network is the mostdirectly factor in affecting customer service.Automation technology plays an important role inimproving the reliability of power supply, reducing failure outage time, reducing the scope offault, enhancing the enterprise’s economic and social benefit, so the promotion andimplementation of distribution automation is an important subject of enterprise.This paper describes the status and development trend of distribution automation both athome and abroad, research and analysis the method of realizing distribution automationsystem. Describes the transformation of terminal requirements according to GuangdongPower Grid Co, and determine the technical scheme of automatic construction of Huiyangdistrict--In situ type feeder automation,focusing on overhead network which has fault of highfrequency, improving the reliability of power supply and automation level in Huiyang district.From the fixed value calculation and principle, it tells the methods of setting the value of themain circuit breaker switch in the first stage and piecewise load switch parameters, and finallydescribes the integrated scheme of distribution automation system, showing the architectureand communication network of distribution automation system.This paper is based on analyzing the technical scheme of distribution automation,according to the requirements and standard of the Guangdong Power Grid Co, combined withthe current situation of distribution network of Huiyang district, proposed the constructionscheme of distribution automation. |
