摘　　要：三峡电源电站在三峡电厂及外部电网交流电源消失时承担黑启动的重要任务,而电源电站机组调速系统能够在厂用交流电消失时启动机组及正常运行,是确保机组黑启动成功的关键。文中围绕电源电站调速器具备黑启动功能这一主要特点,分析了电源电站调速器油压装置的设计特点、黑启动时油压装置的运行情况和控制流程、调速器孤网运行功能实现和孤网运行试验情况。The Three Gorges power source station undertakes the important task of black-start when the AC power supply of the Three Gorges Power Plant and the external power grid disappears. And the Unit＇s governing system of the power source station, which could start up units for normal operation after station AC power disappears, is the key to success of the black-start. This paper analyzes the design features of the oil pressure unit of the governor of the power source station, operation condition and control flow of the oil pressure unit in black-start, the realization of black-start function of the governor of the power source station, and the test conditions of isolated operation.
