Alternative Title
Simulation of Induction Motors with Magnetic Saturation of Leakage Inductances
Abstract
전동기 기동에서, 전동기를 준과도상태로 다루기에는 너무 빨리 가속하기 때문에 일정한 회로정수를 이용하는 방법으로는 기동시 기동전류나 기동 토오크 등을 정확히 계산할 수 없다. 이 논문은 자기포화하는 누설 인덕턴스와 자화 인덕턴스를 전류의 함수로 하여 전동기의 과도상태를 시뮬레이션할 수 있는 간단한 한 방법을 제안한다. 시뮬레이션 결과에서 과도상태에서 자기포화를 고려한 경우와 그렇지 아니한 경우에 전류, 토오크, 등 전기적 현상들이 크게 다르게 나타남을 볼 수 있었다. 이 방법은 동기전동기 해석에도 적용이 가능할 것이다.
The starting current, torque, and other phenomena of an induction machine can not be calculated exactly with constant circuit parameters, since the machine is accelerated too fast to be considered in the quasi-steady state. This paper presents a simple method to simulate the transient phenomena of induction motors with the saturable leakage inductance and magnetizing inductance, which are functions of the machine current. In the result, it is found that there are a lot differences in current, torque, and other phenomena between the method with magnetic saturation and the other method with constant circuit parameters. The method is equally applicable to the analysis of synchronous machines.
