灵敏度高、调试维护方便的电气液压调速器,在我国水电机组上的广泛应用,对进一步发挥水轮发电机组快速启动、担负峰荷的优势,起到了明显的推动作用。但是,运行中暴露的一些不足之处,表明设计、制造、安装、维护各环节中存在程度不同的问题,轻则影响调节性能,重则无法保证安全运行。据调查,全国约有25％的 High sensitivity, easy commissioning and maintenance of the electrical hydraulic governor, widely used in our hydropower units, to give full play to the rapid start-up of hydro-generating units, peak loads play a significant role, has played a significant role in promoting. However, some shortcomings exposed during operation indicate that there are different degrees of problems in the design, manufacture, installation and maintenance of various links, ranging from the impact of regulatory performance, but failing to guarantee safe operation. According to the survey, about 25% of the country
