摘要(Abstract)：

目前国内对燃气设备的研究中，针对控制阀等阀门设备的研究仍有欠缺，其模型大多停留在单个的液压阀门或液压缸研究。对此，利用Simulink/Simscape组件针对从PI控制器到燃气管道的整个燃气轮机燃料控制阀进行建模，并针对固定节流孔堵塞、滑阀阀芯磨损、液压油污染等故障进行模拟分析，探讨其故障形式及原因。结果表明：喷嘴挡板阀单侧固定节流孔堵塞、滑阀阀芯的磨损以及液压油中的杂质均会不同程度地造成阀门的响应迟缓，甚至堵塞卡滞。最后，针对当前电厂对阀门数据的监测提出如下建议：可以根据实际运行状况使用电反馈伺服阀引入伺服阀阀芯位移信号及液压缸活塞位移等参数的监控以便更好地判断阀门健康状态。
