摘要

本文研究了具有一般转子偏心和定子并联路径的同步电机的反流问题。REs产生上升环电流，可以通过Fortescue的空间变换在复域中转换。大量的模拟结果表明，在2极的SMs中，REs主要刺激2(p±1)极电流空间矢量，具有典型的心形图案。采用多相对称分量对仿真结果进行了验证，得到了从轨迹幅值出发进行故障严重程度评估的理论公式。实验验证在一篇论文中进行，其中Labview虚拟仪器检测17kVA四极发电机中的自然和人工REs。

Study of cardioid-shaped loop current space vector trajectories for rotor eccentricity detection in power synchronous machines

This paper studies the reaction currents of a synchronous machine (SM) with general rotor eccentricity (RE) and parallel paths in the stator. REs make rise loop currents which can be translated in the complex domain through a Fortescue's space-transformation. Extensive simulations show that mainly 2(p±1)-pole current space vectors are stimulated by REs in 2p-pole SMs, with typical cardioid-shaped patterns. The simulation results were justified by using multi-phase symmetrical components, and theoretical formulas were obtained for fault severity assessment starting from loci amplitudes. Experimental verification was shown in a companion paper, where a Labview virtual instrument detects natural and artificial REs in a 17kVA four-pole generator.
