| How to reduce transmission line lightning disturbance accident become an important subject of power system safe and stable operation, because the transmission line has very important position on ensuring safe operation of power grid.At the start of transmission engineering, lightning trip-out of overhead transmission lines has always a difficult problem in safe power supply.Power grid failure accounted for most of the accident to transmission line while lightning trip-out has larger proportion of a ransmission line fault.For transmission lines of the mountains, line fault is basically caused by lightning strike tripping operation, so the frequency of power grid accident can be reduced through preventing lightning tripping.Therefore, search for more effective line lightning protection measures is always a focus problem of power workers around the world.In this paper according to the shandong province laiwu mountains to the actual situation of electric power line from lightning disturbance attacks, by collecting historical data, statistics of the number, location and type of lightning electric line data, Analysis the reason of the lightning strike and type, To find and determine the rule of lightning electric power line features, classification and main reasons 。 Combined with the specific geographical environment of laiwu city in shandong province power grid and the current running of electric power line lightning protection measures, by applying new technology, new equipment and new materials, to ensure the security and stability of electric power line, the operation of efficient and reliable, economic and environmental protection, Improve the power line lightning disaster resistance。 In other parts of the mountainous area power grid can be reference in this paper, the research methods and research results, In the concrete practice of the popularization and application. |
