Inducting current and heating evaluation of system resonant wave and negative sequence creating in the hydraulic generator

采用多回路法建立的凸极同步电机 d、q 系统模型,导出了在外加任意谐波或负序时阻尼条电流分布及其发热的稳态计算方法。通过实例计算结果,分析和说明电力系统谐波和负序将在阻尼绕组中引起电流和温升的分布情况。以利工程技术人员分析解决相应故障。

This paper introduces the multi-loop method to build salient synchronous motor d & q system model, and deduces current distribution and its heating static computing method under exerting arbitrary resonant wave and negative.In addition,it analyzes and illustrates the inducting current and heating distribution of power system resonant wave and negative sequence creating in the windings,which is helpful to solve troubles for engineer and technician.
