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 Station undertakes the important task of black start when the AC power of the Three Gorges Power Station and the external power grid disappears. However, the speed regulation system of the power station unit can start the unit and operate normally when the AC power of the plant disappears, which is the key to ensure the black start of the unit successfully. Focusing on the main features of black start function of power plant governor, this paper analyzes the design features of power plant governor hydraulic device, the operation and control flow of hydraulic device during black start, the function of governor isolated network Achieve and isolated network operation test situation.
