子方阵法在燃气轮机故障数学模型建立过程中的应用

Research and Application of Sub-square Matrix Method during the Establishment of the Gas Turbine’s Fault Math Model

针对燃气轮机故障诊断的故障数学模型建立过程中所出现的不定方程问题,提出了子方阵分析法。该方法成功地解决了由于可测参数少于性能参数所带来的不定方程问题,并运用于某型燃气轮机。实践证明这种方法是有效的。

This passage is aimed to solve the problem of unstale equation during establishing mathemetical model in gas turbine fault diagnosis by sub-square matrix method. This method successfully solves the problem of unstale equation because the observable parameter is short to the performance parameter. Meanwhile the method to some type of gas turbine and the result proves is applied that the method is effective.
