摘要：
The finite element software ANSYS Maxwell is applied to calculate the equivalent circuit parameters of healthy winding and their correctness is verified by comparing them with those calculated by the analytical formulas. The winding models for different deformation types and degrees are then established based on ANSYS Maxwell. The changes of equivalent circuit parameters are obtained by the simulations for three winding deformation types, i.e. central displacement, radial deformation and inter-disk distance variation. Based on these equivalent circuit parameters, the circuit simulation software PSPICE is applied to simulate the frequency-response characteristic curves of deformed windings and the effects of three deformation types on the frequency and amplitude of resonance point are obtained. © 2017, Electric Power Automation Equipment Press.
