【摘要】 本文讨论了汽轮机液压调节系统故障的诊断方法,提出了专家系统和参数检测两种方法。本文为专家系统提供了一种以模糊数学为基础的故障诊断方法,为参数检测法提供了一种模式识别法,后者结合国产200MW汽轮机液压调节系统做了仿真计算,取得了可靠的诊断结果。更多还原

【Abstract】 In this paper two diagnostic methods for the failure detection of steam turbine MHC, the Expert System Method and Parameter Detection Method, are given. The Expert System for the fault diagnosis is based on the fuzzy methmatics, for the Parameter Detection Method a model identification method is given, by using the model identification method the simulation is made for the 200MW steam turbine MHC, and is proved effective for the failure detection.更多还原
