摘要: This paper presents a three-dimensional coupled approach for transient simulation of electromagnetic devices. The is based on the A-V-A formulation, in which eddy current field and electric circuit equations are solved simultaneously. Newton-Raphson procedure has been used to take magnetic non-linearity into account. short-circuit state 240000 kVA power transformer simulated by approach.
