Substation forced to be built in the mountains, with complex geological conditions and harsh natural conditions. The summer rainy season and the winter snow and ice have caused serious threats to the security on the mountain substation geological safety and have great impact on the power grid stability. Currently, there is no effective and continuous monitoring tool for mountain substation geological safety. Due to active crustal movement, earthquake, mudslides and other geological disasters increased significantly in some areas. Substation has undergone a number of serious geological security incidents. To solve such problems, the project intends to research and apply on the mountain substation geological safety monitoring. Firstly, analyzes the necessity of geological safety monitoring. Secondly, introduces the distributed optical fiber sensing technology, optical monitoring systems and geological safety monitoring system. Finally, makes a simulation experiment and demonstrates the feasibility and effectiveness of the method.

Nowadays, fiber optic technology has been used in sensing. Using the distributed optical fiber sensing technology in the landslide monitoring, the linear strain distribution information of the whole landslide can be obtained, and adopting the Fiber Bragg Grating sensing technology in the landslide monitoring, the key pot strain and displacement information can be gained. This paper firstly reviews the basic principle of optical fiber sensing, and then describes the optical fiber sensing real-time monitoring system by combining with FBG technology, BOTDR technology, database technology and web server technology, and finally presents a field application experiment using the real-time monitoring system in Ripley landslide in Canada. The experiment indicated that the real-time monitoring system can be realized real-time monitoring of FBG and BOTDR for landslide, and the experience can be extended to other landslide.
