| Abstract: | This paper introduces the reformation of the station-service power supply equipment at Chencun Hydropower Station. RCS-type microcomputer-based transformer protection is applied and improved, and PLC designed by the engineers at Chencun Hydropower Station is used for the auto-changeover control system of power supply. The reliability, applicability and automation level of the system are improved thoroughly. The structure of the system is simple and reliable, and the program is maintainable, thus the system is worth popularizing. |
