摘要
研究了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运行态时,为提高设备利用率,使回馈器运行在有源电力滤波状态。以并联型有源电力滤波器为对象,对其拓扑结构、补偿分量的检测算法、控制策略等问题作了系统研究。实验结果表明,该回馈器工作稳定可靠,具有良好的动静态性能。仿真结果表明,该回馈器能准确补偿谐波电流和无功功率,动态响应速度快。
The paper researches the energy-feedback device which has double functions：active power filters and energyfeedback.The energy is return to the power-grid through the device when it works at the state of regeneration energy.The device works at the state of active power filters for improve the value in use when it do not work at the state of regeneration energy.Taking paralleled active power filter as investigated subject,it makes systematic study for topology,detection algorithm of compensation reference,control strategies of the APF.Simulation results by Matlab are given to show that the device has more exact compensation effectiveness and rapidly dynamic response.
