Estimación de parámetros eléctricos de la máquina sincrónica utilizando MATLAB-Simulink

Abstract

Estimation of the synchronous machine parameters using MATLAB-Simulink is a technical study to improve electrical simulations of the synchronous machine. The proposed work is achieved using international standards at the Laboratory of Electric Machines of National Polytechnic School. Field tests are execute at the laboratory of electrical machines, where two stages are developed. The first one gather synchronous machine parameters using international standards IEEE Std 115. Whilst the second stage considers the application of abnormal event to find an experimental diagram. In the subsequent stage, the computational tool MATLAB-Simulink allows simulate the synchronous machine under a three-phase short circuit applied to the terminals of the armature. The current waveform in phase C of the generator synchronous is the simulation response for the machine in the form of an oscillogram. This stage uses the following resources: the electrical parameters, the generic model of the synchronous machine and the applied disturbance. The estimation of the synchronous machine parameters is conducted using the MATLAB-Simulink optimization tool, which is a powerful resource to tune the electrical parameters on the model of the synchronous machine. Both experimental data and simulated data is used to tune the synchronous machine parameters.
