For the 300MW steam turbine in our plant, the No.2, No.4 and No.6 control valves often have large jitter at low load, but not at high load.

If the tone jitter also occurs when it is static, it may be that the tone servo card is not well adjusted, such as the integration effect is too strong. If the tone does not shake at rest, it may be that the flow characteristics of DEH tone are not set well (especially when the tone is small) and reset. If you don't understand anything else, ask a master in the industry. Or go to Polaris Power Forum and ask, there are many experts there, and there is also Polaris Power Recruitment Network, which is good and professional enough to find a job in the power industry.
