Method and system for identifying distribution parameters of electromagnetic voltage transformer

Abstract

The invention discloses a method and a system for identifying distribution parameters of an electromagnetic voltage transformer, and belongs to the technical field of alternating-current voltage testing. The method comprises the following steps: carrying out equivalence on the electromagnetic voltage transformer, and enabling the electromagnetic voltage transformer to be equivalent to a two-port equivalent broadband model; determining an admittance parameter matrix of the two-port equivalent broadband model; and based on the admittance parameter matrix of the two-port equivalent broadband model, identifying the optimal distribution parameter of the electromagnetic voltage transformer. The method is simple in calculation and accurate and reliable in result.
