Research On Wind Resistance Improvement Of Overhead Line Of 10kV Distribution Network

The overhead line of 10 kV distribution network has a large power supply capacity and a large distribution range,which leads to a greater impact of natural disasters.In the coastal areas of Guangdong,especially in Western Guangdong,the peak season of typhoon landing is the third quarter.Typhoon brings great harm to the safe operation of power grid.Therefore,it is of great significance to study the landing characteristics of typhoon and its harm to the overhead line of 10 kV distribution network,as well as the wind resistance of the overhead line of 10 kV distribution network.This paper summarizes and divides the transformation of the wind resistance of the overhead line of the distribution network from four aspects: the analysis of the influence of Typhoon on the overhead line of the 10 kV distribution network,the analysis of the influencing factors and causes of the insufficient wind resistance of the overhead line of the 10 kV distribution network,the design and Application of the wind resistance reinforcement of the overhead line of the 10 kV distribution network,and the economic effect of the application of the wind resistance transformation of the overhead line of the 10 kV distribution network.Finally,some conclusions are drawn.On this basis,this paper studies and analyses the hazards and characteristics of Typhoon on 10 kV overhead distribution lines,summarizes the reasons for the weak wind resistance of 10 kV overhead distribution lines,and puts forward the transformation scheme to enhance the wind resistance.At the same time,it puts forward the finite element modeling method,carries out simulation calculation with the help of software.By studying the stability of overhead lines under wind load,the effectiveness of wind-resistant renovation measures is verified.Through the research on the wind resistance transformation of the overhead line of 10 kV distribution network,the reinforcement of the overhead line of 10 kV distribution network is realized,the stability and wind resistance of the overhead line of 10 kV distribution network are improved,the safe and stable power supply of the transmission line of distribution network is guaranteed,and the influence and loss of typhoon to distribution network are minimized.At the same time,it has certain reference significance for the design,safety construction and technical transformation of overhead distribution network lines.
