摘　　要：通过对上海汽轮机厂600 MW超临界汽轮机高压主汽门(total valve,TV)-调节汽门(governing valve,GV)单边联合阀门活动试验的研究,提出了在试验中通过协调控制系统(coordination control system,CCS)汽轮机主控对GV进行调节的方法,解决了原有指令平衡分配方式严重依赖阀门特性的缺点,同时对取消试验的部分限制条件进行了优化。By studying on unilateral joint valve activity test of high pressure total valve-governing valve of 600 MW supercritical steam turbine in Shanghai steam turbine plant, this paper proposes a method for adjusting governing valve by steam master of coordination control system in the test which is successful in solving problem of original instruction balance distribution mode seriously relying on valve characteristics. Meanwhile, it carries out optimization on parts of constraint conditions for revocatory test.
