摘要
为了模拟同步电机的准稳态异步起动过程,本文考虑起动绕组的具体分布,建立了凸极同步电机稳态开步运行情况下的数学模型,并参考文献〔1〕建立了瞬态起动过程的计算模型。以一台680kVA同步电机为例,对准稳态异步起动过程和不同条件下的瞬态起动过程进行了计算分析。得到了一些对实际工程有一定意义的结论。
Abstract To simulate quasi-steady state asynchronous starting process of synchronous machines, a mathematic model of steady -state asynchronous operation of synchronous machine is set up in this paper, where practical distribution of damper windings is taken into account. And the calculation model of ent starting process is set up. By this method, taking a synchronous motor as an example , a quasi-steady state asynchronous starting process is calculated. The results are compared with those of transient starting processes at different conditions calcalated by state -variable method, some useful conclusions for engineering are obtained.
