Analysis of the circuit parameters of induction motor d-q model using finite element method
Abstract
본 논문에서는 3상 유도전동기의 d-q등가모델의 회로정수를 구하는 한 방법을 제시하였다. 자기해석은 철심과 슬롯 형상을 정확하게 반영할 수 있는 유한 요소법을 이용하였고, 철심의 자기포화현상도 고려하였다. 제시된 방법은 반복계산을 통하여 회로정수를 구하는 방법에 비해 계산시간을 절약할 수 있다. 그리고 산출된 각 회로정수는 전류의 변화에 따라 다른 값을 가짐을 확인할 수 있었다.
This paper presents a method for determining of the equivalent d-q model parameters of three-phase squirrel cage induction motors. The method is based on the use of a finite-element field calculation which enables the precise slot geometry to be modelled accurately, and includes the effects of magnetic saturation of iron core. The proposed mothod can reduce computational costs compared with the method that needs the iterative field analysis to obtain the parameters. It is verified that the circuit parameters are shown as functions of the current.
