Modeling and Simulation with a Variable Speed Drive System of a Electric Motor Using MATLAB/SIMULINK

MATLAB/SIMULINK를 이용한 전동기 가변속 구동시스템 모델링 및 시뮬레이션

The variable speed drive system of a electric motor is popular in industry due to its economical aspect and simplicity of implementation, comparing with a steam turbine or the other engine driven. For a large pumping load like a feedwater pump rated about or more than 20,000㎾, a synchronous motor could be primarily considered. In this paper, we studied the modelling of a variable speed drive system consisted with a load commutated inverter(LCI) and a brushless sailent pole rotor synchronous motor(SM) using MATLAB/SIMULINK. Simulation was performed with a small SM motor parameters.
