水轮机调节是根据偏离了额定工况的转速偏差信号,调节水轮机导水机构,不断地维持水轮发电机功率与负荷功率的平衡。机组速度反馈是大多数水轮机控制系统最基本的输入量,因此,测频装置是决定水轮发电机组及调速器安全、稳定运行极为关键的部件。本文主要介绍齿盘测频+残压测频在乌江渡发电厂#1厂水轮机上的应用。
Turbine adjustment is based on deviation from the rated condition of the speed deviation signal, regulating turbine hydraulic institutions, continue to maintain the hydro-generator power and load power balance. Unit speed feedback is the most basic input for most turbine control systems. Therefore, the frequency measurement unit is the key component that determines the safe and stable operation of hydroelectric generators and governors. This article mainly introduces the application of gear tooth frequency measurement + residual voltage frequency measurement in the turbine of # 1 plant in Wujiangdu Power Plant.
