摘　　要：三河口水电站既有发电又有供水要求,对厂用电系统的供电的可靠性和灵活性要求较高。通过对三河口水电站厂用电系统的电源引接、接线方式等方面的问题进行探讨,提出采用发电机10.5kV电压母线接两路厂用主工作电源,另引接两路外来10kV厂用备用电源供电,成功解决了机组直接启动时,母线电压降低对厂用系统造成的影响,为三河口电站的安全运行奠定了基础。Sanhekou hydropower station has not only power generation but also water supply requirements, the reliability and flexibility of the power supply system must meet the higher requirements. Through the connection of power supply and wiring of Sanhekou Hydropower Station, it is proposed to use the generator 10.5kV voltage bus to connect the two main power supply, and the other two external power supply of 10kV auxiliary power supply, Successfully solved the unit started directly, the bus voltage drop on the impact of the plant system for the Sanhekou power station laid the foundation for the safe operation.
