The rainwater collection and utilization technology in substation was investigated, and then a novel water-saving technology system for green substations is presented in this paper. A 220kV substation was chosen as the example to analyze the system. The results showed that it can save 278.5m³ water resource. It can provide important reference for rainwater collection and utilization in unattended substation.
