研究一种具有滤波与能量回馈双功能的电梯能量回馈器,当电梯处于能量再生状态运行时,回馈器将能量回馈到电网;当电梯处于非能量再生状态运行时,即回馈器处于闲置状态时,为了提高设备利用率,使回馈器运行在有源电力滤波状态。本文以并联型有源电力滤波器为研究对象,对其拓扑结构、补偿分量的检测算法、控制策略等问题作了较系统研究。MATLAB仿真结果表明,该回馈器能够准确地补偿谐波电流和无功功率,动态响应速度也很快。
研究一種具有濾波與能量迴饋雙功能的電梯能量迴饋器,噹電梯處于能量再生狀態運行時,迴饋器將能量迴饋到電網;噹電梯處于非能量再生狀態運行時,即迴饋器處于閒置狀態時,為瞭提高設備利用率,使迴饋器運行在有源電力濾波狀態。本文以併聯型有源電力濾波器為研究對象,對其拓撲結構、補償分量的檢測算法、控製策略等問題作瞭較繫統研究。MATLAB倣真結果錶明,該迴饋器能夠準確地補償諧波電流和無功功率,動態響應速度也很快。
