Study On Power Supply Reliability Of Distribution Network In Jidong Oilfield

Distribution network is an important part of power system,it directly provides electric energy to users.The reliability of distribution network is mainly manifested in the distribution network equipment.The operation of the distribution network equipment defects,influence of external factors such as management and equipment.The distribution network equipment operation directly reflects the level of power grid enterprises.This paper first understand the domestic and international distribution network reliability research status,development stage of each domestic distribution automation,distribution automation and the future development trend is prospected.Secondly introduces the overhead wiring form of oil distribution on land,in the form of cable wiring on the island,on the overall operation of oilfield power grid are analyzed,find out the main factors affecting the Ji dong Oilfield distribution network power supply reliability of lightning,galloping,external damage,equipment defects,wiring form is proposed.The lightning protection of distribution network,wire dancing prevention measures against external damage,equipment defects and measures,part of the 10 kV overhead oil In the end,the paper puts forward the reform measures,and puts forward the upgrading scheme of distribution automation in Jidong Oilfield,in order to improve the reliability of distribution network.
