不控整流电路不平衡电压工况特性分析
Analysis on Operation Performance of Uncontrolled Rectifier Circuit Under Unbalance Voltage Condition
摘要
Abstract
Slight unbalanced voltage can cause large unbalanced currents in the uncontrolled rectifier circuit and bring large third harmonic currents which can damage the grid seriously.The input harmonic currents of the rectifier circuit was analyzed under unbalanced voltage condition,the relation curve between unbalanced factor of input current, third harmonic currents and loads in slight unbalanced voltage which could guide the filter′s design of rectifier circuit were described in detail.The rectifier circuit operation modes were analyzed and the input/output currents models were built and the boundary conditions between each mode were derived.Finally,the simulation and experiments are given to verify this proposed model.关键词
