摘要:
 摘要:针对传统动态电压恢复器(dynamic voltage restorer, DVR)拓扑结构直流侧电压等级高,逆变单元输出电压波形畸变率大及其损耗亦较高的问题,依据开放式绕组原理提出新型DVR拓扑结构。研究了新型DVR拓扑实现低谐波畸变率和低直流侧电压幅值的方法;建立了新型DVR等效电路模型,并给出新型DVR拓扑的控制策略。同时分析对比了新型DVR与传统DVR拓扑的功耗,结果表明新型DVR功耗较低。最后,在MATLAB/SIMULINK平台搭建仿真模型,仿真结果证明所提出的DVR拓扑结构性能优越,补偿精度高。
Abstract:
 Abstract:This paper proposed a new topology of dynamic voltage restorer (DVR) based on the concept of openend winding, considering higher dclink rating, harmonic distortion of voltage generated by inverter and power loss of converter The methods to decrease the harmonic distortion of voltage and amplitude of dclink were studied. We established equivalent circuit model and then the control strategy was presented Meanwhile, compared to the traditional DVR, the proposed DVR has better performance on power loss Finally, we build the simulation model on MATLAB/SIMMULINK and the simulation results show that the new topology structure has superior performance and high compensation accuracy
