【摘要】 本文研究了三相倍极感应励磁同步发电机中倍极静止磁场的存在对电机运行性能的影响，并引入了反映定子直流绕组感应产生转子主励磁磁势能力的磁势感应系数这一重要概念。结果表明：采用倍极感应励磁对电机的运行性能无明显不良影响，但由于磁势感应系数较低，所需定子直流绕组安匝数较大，导致电机主绕组容量下降较多。文中分析了造成磁势感应系数低的原因，探讨了改善途径更多还原

【Abstract】 Effects of double-pole stationary magnetic field on performance of the 3-phase synchronous generator with double-pole induced-excitation are investigated.By introducing the concept of mmf transfer coefficient,the ability of producing rotor main field by stator DC winding is studied.It is concluded that the presence of the double-pole stationary magnetic field has little effect on performance of the generator,but a relatively large turn number of stator DC winding is required due to low mmf transfer coefficient,and the capacity of the winding is thus obviously decreased.The reason causing low mmf transfer coefficient is analysed and impovement measures are discussed.更多还原
