The requirement for leakage reactance on stator of PMSM supplied by voltage type inverter is analyzed, and some parameters are selected, such as electromagnetic load, slots shape of stator and so on. 分析了电压型逆变器供电的永磁同步电动机对定子漏抗的要求,确定了电磁负荷以及定子槽形等参数的选取原则。
An equivalent circuit model of the rectifier loaded 3 phase synchronous generator with d axis subtransient reactance x ″ d equal to q axis subtransient reactance x ″ q is developed for steady state and quasi steady state analysis of the synchronous rectifier load system. 在d轴与q轴超瞬变电抗值相差不大的条件下,建立了带整流负载的三相同步发电机的等效电路模型,该模型可用于同步发电机整流系统稳态和似稳态过程的分析计算。
This iterative method can not only determine Potier reactance Xp accurately, but use to analyse the excitation current, load angle and armature reaction. 这种迭代方法不仅可以准确地测试保梯电抗,而且对于稳态运行时励磁电流、功角、电枢反应的分析都有重要的作用。
This paper extends the concept of general parameter filter given in reference [ 2], and arrives at the general frequency characteristic approximation theory of reactance two-port networks in the case of arbitrary generator and load impedances ( Non-Foster positive-real functions). 本文延伸文献[2]关于通用参数滤波的概念,得出有关电抗二端对网络在两侧都端接阻抗(非Foster正实函数形式)情况下的频率特性逼近的一般性理论。
The augment of external reactance and active power load reduces the inherent damping; 外部电抗和有功负载的增大导致固有阻尼能力下降;
