| 摘 要： | 凸极同步发电机空载电势波形畸变率是衡量发电机性能的重要指标，主要取决于它的气隙磁场，后者受到诸多因素的影响，计算十分复杂。将引入“饱和谐波磁导法”的概念［１］，综合运用了传统的解析法与现代的数值法，既较准确地计算了气隙磁场，又成功地描述了气隙中齿谐波磁场产生的“动态”过程。计算结果与实验结果吻合较好，能满足设计前对电机空载电势的预估

| Abstract: | The no load EMF waveform deriation ratio of the salient pole synchronous generator is one of its important technical data and depends mainly on the waveform of the no load air gapmagnetic field, which is seriously influenced by many complex factors and is difficult to calculate. In this paper, the method of saturated permeance harmonic is intruduced. By superimposing the conventional analytic method and the modern numerical method, the air gap magnetic field can be computed accurately, and dynamic static feature of air gap tocth harmonic field is described very successfully. finally, the calculated and tested results are good coincidences, so that the mathematical model and method which we proposed are acceptable for engineering purpose. |
