摘　　要：针对汽轮机阀门特性对机组负荷响应及一次调频能力的影响,结合一台600MW机组大修后的实践过程,介绍了对阀门特性进行试验和对其流量曲线进行优化的方法。结果表明:阀门流量曲线优化后,阀门控制方式切换过程中负荷波动量较小,机组一次调频能力增强。To improve the valve response characteristics to unit load and the primary frequency modulation capability of gas turbine, a method to test the valve characteristics and to optimize its flow characteristic curves was proposed, based on operation practice of a 600 MW unit after overhaul. Results show that the load fluctuation in switching process of valve control mode is relatively small and the primary frequency modulation capability of unit is enhanced after optimization of the valve flow characteristic curves.
