摘要
本文用有限元法研究电机动态过程中参数变化的非正弦和饱和特性,依此为基础建立起同步发电机状态数学模型,实现了磁场参数的有限元计算与电机动特性数字仿真的有机结合。因此本项研究的意义在于,在电机制造前,就能予估电机的动特性。最后以发电机三相突然空载短路为例,在计算机上求解其动态行为,并与实验进行了对照。
This paper deals with the reseach of harmonic and saturation nonlienear of dynamical parameter by finite element mothod,( FEM) .Based on this a mathematical model in the state space is set up for numerical simulation. Thus is realized the combination of Parameter calculation by FEM with numerical simulation.This study is helpful in estimation of the dynanical response before manufacturing of a synchronous generator. Finally, a numerical example for 3-phase shorte-circuit of generator is solved. The results are compered with the experimental results.
