递推最小二乘法在变压器绕组参数辨识中的研究应用
Application of Recursive Least Squares Method in Transformer Winding Parameter Identification
摘要
Abstract
Transformer is one of the most important electrical equipments in power system .With the characteristic of leakage inductance change caused by winding deformation ,on-line parameters identification of transformer winding is put for-ward higher requirements .In this paper ,double winding transformer modelis simulated and the least square method is adopt-ed to realize accurate on-line identification of the transformer parameters .The simple system is simulated by Matlab/SIM U-LINK and the resultis shows that the algorithm is not affected by the load factor and power factor .The algorithm can identify the transformer winding parameters accurately and achieve on-line monitoring .关键词
