内燃机驱动的自激异步发电系统建模仿真研究

Simulation Research of Modeling of Self-excited Asynchronous Generator System Driven by Internal Combustion

基于Matlab/Simulink软件建立了异步发电机仿真模型,针对采用的笼型异步电动机数据,确定了M文件中异步发电机模型中的相关参数;详细说明了四冲程内燃机在Matlab软件下的建模实现过程和原理;建立了以内燃机为原动机的自激异步发电系统。仿真结果表明,接入负载时,系统有明显的调整过程,通过对比分析有无原动机时电压的变化情况验证了模型的正确性,为实际内燃机驱动的自激异步发电系统研制提供了强有力的理论依据。

Firstly, a simulation model of asynchronous generator based on Matlab/Simulink was built, and correlative parameters of the model of asynchronous generator were confirmed in M file in view of data of case asynchronous motor. Secondly, realization procedure and principle of modeling of four-stroke internal combustion in Matlab were explained in details. Finally, self-excited asynchronous generator system driven by internal combustion was established. The simulation results showed that the system has an obvious adjusting process when it is connected with load. The correctness of the model was verified through analysis of change of voltage with prime mover or not. It provided theoretical basis for developing actual self-excited asynchronous generator system driven by internal combustion.
