摘要
本文以变换和滤波理论为基础,提出了电力负荷机理式集结模型参数辨识的新方法。并应用于感应电动机集结负荷模型,以某个大型造纸工业负荷进行了验证。研究表明,按所建模型得到的仿真结果与实测值吻合甚好。与国外一些文献介绍的最小二乘法相比,本文方法具有节省计算量和较为精确的优点。
A novel approach is proposed for physically based dynamic load modelling. This approach needs no priori knowledge of the parameters of individual load nor repeatedly solution of the state equations. The parameters of the model can be estimated fastly and recursively by NLRF method developed in [ 9 ] according to the data recorded in field-site tests.The case study shows that the developed model can satisfactorily reproduce the input-output behavior of load group during fault conditions. The simulation results of this model are more close to the measured ones than those of the model developed by least-square method.
