Employment of Complementary Wind-solar Power Supply System in Songzikeng Reservoir

A complementary wind-solar power supply system was applied in the anti-terrorism video system of Songzikeng reservoir in Shenzhen to solve power supply problem of video camera without AC 220 V in remote districts. This paper describes work principle, some functions, networking, reliability and effects of the power supply system, analyzes technical conditions of its application in Songzikeng reservoir. Power consumption calculation verifies that this method can meet system requirements for power supply and the application of the power supply system is proved to be successful.
