摘　　要：就汽轮机长期运行或者大修之后DEH系统阀门流量特性偏离原来曲线的问题,对某600MW机组阀门流量特性试验进行说明,并对DEH系统阀门流量曲线进行校正,校正后机组AGC响应及一次调频能力增强。此工作对汽轮机组阀门流量特性曲线校正有一定的参考价值。Aiming at the problem that DEH system valve flow characteristic deviation from the original curve after long-term operation or overhaul, this paper illustrats the test of valve flow characteristic and the characteristic curve of DEH system has been adjusted. After adjustment, unit AGC response and primary frequency control ability has been strengthened. Above all, there are some reference value in the adjustment of the flow characteristic curve of turbine.
