| 摘 要： | 以泰国NARESUANA电站灯泡贯流式水轮发电机组及其调速器为例证,着重说明了灯泡贯流机组的特点,阐述了调速器的步进电机系统研制和应用:1采用适应式、变结构、变参数、并联PID调节模式,使机组在不同状态下均能稳定运行;2采用变参数导叶分段关闭装置,根据水头、负荷、频率等机组工况自动改变导叶分段关闭投入点,减少了快速关闭时造成水击压力的升高,并防止涌浪、低频及水锤的发生;3桨叶根据机组频率自动改变关闭速度,防止涌浪、低频及水锤的发生。

| Abstract: | Bulb hydraulic generating units are development very quickly in recent years in low water-head power station for its smaller volume, compact construction and high efficiency. Turbine governor as important control equipment in hydraulic power station provide high-quality, reliable power protection for the industrial production and people's daily lives, the regulation performance will affect the power quality and power plant safety and economic operation. A Special regulation model for bulb generating units has been introduced in this paper through the Thailand NARESUANA station on-site testing. |
