新型燃气轮机热参数故障诊断数学模型的研究和应用

The research and application of a new fault model of thermal parameter for Gas turbine

介绍了一种新型燃气轮机热参数故障模型。与以往的热参数故障模型有所不同的是该模型对由故障导致的特性线移动所引起的性能变化及由部件匹配引起的性能变化进行了分离 ,提高了模型的准确性和精度。此外 。

A new fault model of thermal parameter for Gas Turbine is introduced in the paper.Since the performance deterioration due to the movement of performance curve caused by fault is separated from the performance change owing to component matching,this model is different from others.And the separation can improve the precision of the fault model.Furthermore,a fault matrix deduced from that model can resolve the problem that the numbers of measurable parameters are not enough to acquire the performance parameters.
