概述水轮机调速器是水电站核心控制设备之一,承担着机组的导叶开度、机组频率、机组功率的自动控制。随着国内各巨型水电机组的陆续投产,水电所占电力系统负荷的比例日趋加大,这对调速器的控制机理、可靠性和灵敏性要求日趋更高。同时,随着科技的整体进步,电力系统对调速器的要求也越来越高,电网对水电机组的快速并网、一次调频考核、带负荷速度等都有着具体的标准和严格考核。所以,大型
Overview Turbine governor is one of the core control equipment of hydropower station, which undertakes the automatic control of the guide vane opening, unit frequency and unit power of the unit. As the domestic giant hydropower units are put into operation one after another, hydropower accounts for an increasingly large proportion of the power system load, which increases the control mechanism, reliability and sensitivity of the governor. At the same time, with the overall progress of science and technology, the requirements of the power system on the speed governor are also getting higher and higher. The power grid has specific standards and rigorous tests on the quick grid connection of hydropower units, a frequency modulation test, and the load speed. So, large
