摘要：The accuracy of transformer parameters is critical for power system analysis and control decision. In practice, the parameters of a transformer may deviate from its factory values due to the influence of environment and equipment aging. An improved model is presented in this paper to identify transformer parameters based on WAMS and SCADA data. Relative errors are considered in the objective function. Cases with different objective functions are examined. The accuracy and convergence of the different method are compared.
