Risk Evaluation Method of Transmission Corridor Based on Panoramic Monitoring

Transmission corridor, which is the key link of the transmission network, is composed of some high voltage and capacity transmission lines. With the increase of outside destroy risk points and transmission lines, the traditional prevention work of outside destroy of transmission line needs more human and material resources. This paper analyzed outside destroy failures of Zhejiang grid. Research on panoramic monitoring of transmission line developed by state grid Zhejiang power company was introduced. Based on the work the risk evaluation method of transmission corridor has been proposed.
