Abstract
In power system simulation,different combination of correlation parameters can create same simulation results and consequently cause non-unique correlation parameters based on practical measuring identification,meanwhile,identifi-cation results may deviate from true values. Therefore,it is necessary to study form mechanism of correalation parameters and identification method. Aiming at non-identifiability of parameters in regards to numerical values,taking traditional structural correlation parameters as basis,problem of numerical correlation parameters were proposed. Meanwhile,these two kinds of correlation parameters were extended as generalized correlation parameters of which the basic feature was line-ar correlation of trace sensitivity. According to characteristic of linear correlation of trace sensitivity,a method for identif-ying generalized correlation parameters by using QR decomposition with column pivoting method and trace sensitivity matc-hing method was proposed. Example result verified effectiveness of this method.关键词
