水轮机调速器抽动故障及消除措施

Tic failure and elimination of turbine governor

水轮机调速器是控制水轮机运行状态、确保电力安全生产的重要水轮机组辅助部分。水轮机调速器抽动,会严重影响水轮机调速器的功能,失去对水轮机运行速度的调节,给水轮机调速器带来性能和状态的威胁,使水轮机调速器失去对水轮机机组的调整与控制作用。可以采取压紧水轮机调速器主阀行程、做好水轮机调速器的滤波处理、调整水轮机调速器伺服阀比例、优化水轮机调速器参数、优化水轮机调速器开机曲线等消除和防止水轮机调速器抽动的方法和措施,在提高水轮机调速器自动化运行可靠性的前提下,保障水轮机调速器运行在安定、可控的范围,进而达到对水轮机组安全生产的需要。

Turbine governor is an important part of the group of auxiliary turbine,it can control the turbine running, ensure that the power production safety. Turbine governor twitch, it will seriously affect the function of turbine governor, losing to the turbine running speed adjustment, turbine governor to threaten the performance and status, so that the loss of the turbine turbine governor adjustment and control unit effect. You can take the compression stroke of the main valve turbine governor, turbine governor to do the filtering process, adjusting the ratio of turbine governor servo valves, turbine governor parameters to optimize, optimize turbine governor and other start-up curve eliminate and prevent turbine methods and measures governor twitching at improving the operational reliability of turbine governor automation premise protect turbine governor running stable, controllable range, and then to the safety of hydraulic turbine production.
