摘　　要：65MW发电机组调节机组负荷的DEH电液伺服控制系统在运行过程中,频繁出现阀门调节信号动作迟缓,波动范围大,不能最大限度地进行发电。通过增设信号隔离器、在线清洗电液伺服阀、定期标定等措施,最终实现DEH系统控制精准、动作迅速,提高发电负荷,实现增产创效。The 65MW generator set of the DEH electro-hydraulic servo control system that regulates the load of the unit frequendy appears in the operation process under the condition of sufficient steam intake,and the valve regulation signal acts slowly and fluctuates widely,the power generation cannot be maximized.In this regard,we added signal isolator,online cleaning electrohydraulic servo valve,regular calibration and other measures to achieve accurate control and rapid action of the DEH system,the power generation load is improved,the production is increased and the economic benefit is created.
