Abstract: Transmission line is a very important power infrastructure, building a multi energy complementary power line supervision system to protect transmission lines from external damage is of great significance to promote social stability and stable economic development. Based on the high-precision positioning hardware, considering the annual climate and environmental conditions, predictable external forces, operation and maintenance strategy and other factors, the integrated planning and operation strategy of multi-energy complementary power line supervision system of Jinhua Dongyang Power Bureau are studied.The results show that the supervision system can reduce the accident rate of circuit damage by 40%, save 3 million life coins, and have good social and economic benefits.
