1.5MW三相电流不平衡故障分析

Analysis of the Imbalance Fault of 1.5MW Three-Phase Alternating Current

在风力发电机组中,变流器电流直接或间接地反应了机组功率、扭矩的大小,同时三相电流之间相互关系也反映了机组的状态,因此三相电流的监测对于机组是至关重要的。论文主要阐述对三相电流不平衡故障的分析和处理过程,并对该故障做了简单总结。

In the wind generating set, the current of converter directly or indirectly reflects the power and torque of the unit, meanwhile, the relationship between three-phase alternating current also reflects the state of the unit, therefore, the monitoring of three-phase alternating current is very important for the unit. The paper mainly expounds the analysis and treatment of the imbalance fault of three-phase alternating current, and makes a simple summary of the fault.
