| 摘 要： | 本文在深入研究抽水蓄能发电电动机电磁设计若干系数计算原理基础上,建立了数值模型并对ALQUEVA水轮发电机,白莲河、宝泉和广州抽水蓄能发电电动机的相关系数进行了计算,为电机的准确设计提供了条件。文中还提出了在电机主要结构保持不变的情况下,通过调整阻尼条在极靴表面的分布来改善电压波形的方法,从而有效地拓宽了电机的可选槽数。此方法已应用于哈电发电电动机以及常规水轮发电机的设计中。

| Abstract: | Calculated model by the FEM is proposed on the basis of the principle of some factors in electromagnetic design on pumped-storage generator-motor(PSGM),and the relative factors of hydrogenerator/ PSGM in power plants such as ALQUEVA,Bailianhe,Baoquan and Guangzhou etc.are calculated.It is helpful for computing parameters of the electric machine accurately.When the major geometry is not changed,voltage waveform gets closer to the sinusoidal form by adjusting damper-bars distribution on the surface of pole-sh... |
