Abstract This paper presents a new technique for the compensation of non-periodic load current. The method provides control references for three co-located devices, each corresponding to one moving calculation window and one decomposed part of the compensated current. They are slow compensator with high power rating, large calculation window, and low switching frequency; fast compensator with lower power rating, shorter calculation window, and higher switching frequency; and the reactive compensator which is an ordinary static VAR compensator (SVC). A fuzzy based adaptive window is proposed for the slow compensator to find the optimum window for different load characteristics. The technique is evaluated using real-world data and controller hardware-in-the-loop (HIL) implementation.

非周期性电流负载的三窗补偿器

摘要 本文提出了一种补偿非周期性负载电流的新技术。该方法为三个共置设备提供了控制参考，每个设备对应一个移动计算窗口和补偿电流的一个分解部分。它们是额定功率大、计算窗口大、开关频率低的慢速补偿器；具有较低额定功率、较短计算窗口和较高开关频率的快速补偿器；无功补偿器是一个普通的静态无功补偿器（SVC）。针对慢速补偿器提出了一种基于模糊的自适应窗口，以找到不同负载特性的最佳窗口。该技术使用实际数据和控制器硬件在环 (HIL) 实现进行评估。
