基于最小方差性能评估的阀门非线性检测方法研究

摘要

A valve nonlinearity detection method based on performance assessment was proposed.Having dai-ly routine data of steam turbine analyzed and a performance index calculated to detect the valve status were im-plemented to warn the valve's failures early.The test results are consistent with real running condition of the power plant.%提出一种基于性能评估的阀门非线性检测方法,利用汽轮机日常运行数据,通过性能指标实时观测汽轮机阀门状态,对阀门故障及时预警,测试结果与电厂实际运行情况一致.
