The Research On Reliability Improvement Of 10kV Distribution Network In Yuhang

As the end of power system which directly connect with extensive power customers,distribution system play an important role in power production and management based on its reliability.Moreover,bothpower enterprises and power customers attach importance to its distribution network reliability as well.Hence,how to improve its distribution network reliability is desired by power enterprises and customers.This dissertation starts with introduction of index of power supply reliability,contains data of 10 kV distribution network reliability in Yuhang district and related impact factors in order to analyze main factors which impact distribution network reliability and propose feasible improvement and measures according to existing questions.What is more,this analysis will combine my practical work experience so as to emphasize the special advantage and remarkable result in improving distribution network reliability through live working in distribution network.On aspect of live work management,I conduct a study to analyze positive effects for improving distribution network reliability from live working through index analysis and practical case.Besides,I put forward to adjust thinking of live working index for refine reliability trend,and extend study of improving distribution network reliability index of live working.There are various measures for improving distribution network reliability.This dissertation proposes feasible measures for improving distribution network reliability,in Yuhang district on aspects of management and technology to improve further structure,power supply capacity and power supply quality in order to transmit safe reliable and high-quality electric power.
