摘要

动态电压恢复器(DVR)已被证明是解决基于电压的电能质量问题的最连贯、有效和经济的解决方案。本文详细介绍了基于重加权零吸引最小均方(RZA-LMS)的DVR的设计、研究和实验验证，解决了电压凹陷、电压膨胀、电压谐波、电压不平衡及其组合等问题。提出了一种基于RZA-LMS的基准电压信号生成控制算法。该算法具有有限时间收敛性、简单性和提高系统对变参数的鲁棒性等特点。采用MATLAB/Simulink和Simpowersystem软件对DVR控制器的可行性进行了评估。利用数字实时模拟器对所提出的DVR的性能进行了实验研究。

Performance investigation of reweighted zero attracting LMS-based dynamic voltage restorer for alleviating diverse power quality problems

Dynamic voltage restorer (DVR) has proven to be the most coherent, effective and economic answer to voltage-based power quality problems. This work details the design, investigation and experimental validation of reweighted zero-attracting least mean square (RZA-LMS) based DVR addressing the issues like voltage sag, voltage swell, voltage harmonics, voltage imbalance and combination of these. The RZA-LMS based control algorithm is proposed for producing reference voltage signals. The features of proposed algorithm include finite-time convergence, simplicity and improvement in the robustness of the system against varying parameters. The viability of DVR controller is assessed by employing MATLAB/Simulink and Simpowersystem software. The performance of proposed DVR is experimentally investigated using digital real-time simulator.
