| Abstract: | The layout area of hydropower station is rather larger and its outdoor lighting parts with reliable grounding nets. The 4 kinds of grounding modes of relay protection in the distribution system for lighting were discussed in this paper. Analysis of the reliability and applicability of grounding mode and the features of lighting location including roads in the hydropower station area, traffic tunnels, living quarters, outdoor switching station and outgoing line platform, the grounding mode of relay protection for the distribution system of outdoor area lighting in hydropower station were proposed. |
