对于偏远地区的配电网，无刷发电系统由于其高可靠性而具有优势。研究人员发现，双定子绕组感应发电机（DSWIG）是一个合适的候选人，为这一目的。本文论述了一种独特的配置DSWIG，它有利于同时通过两个定子绕组在扩展的速度范围内的功率流。两个绕组通过相应的转换器向同一直流母线馈电。在不受控绕组上引入无源调谐滤波器，以改善电能质量，并基于最大化系统有功功率输出的优化准则提供一部分无功功率。提出了一种新的功率分配比指标，并提出了一种通过双绕组分配功率的控制策略。提出了一种寻找最优功率分配比的算法。这是基于每安培绕组电流的最大输出。基于MATLAB/Simulink的仿真研究证实了控制算法的有效性。使用基于dSPACE 1103的实验室原型进行的实验研究证明了该系统的实用性。
For remote area distribution networks, brushless generation systems have an edge due to their high reliability. Researchers have found dual stator winding induction generator (DSWIG) to be one of the suitable candidates for this purpose. This paper deals with a unique configuration of DSWIG, which facilitates simultaneous power flow through both the stator windings in extended speed range. Both the windings feed the same dc-bus through corresponding converters. A passively tuned filter across uncontrolled winding has been introduced to improve power quality and supply a part of the reactive power based on an optimization criterion to maximize active power output from the system. A new index called “power sharing ratio” is introduced and a control strategy to distribute power through both the windings is proposed. An algorithm to find the “optimum power sharing ratio” is developed. This is based on maximum output per ampere of winding current. MATLAB/Simulink-based simulation studies have confirmed the efficacy of the control algorithm. Experimental investigations using a dSPACE 1103-based laboratory prototype have demonstrated the usefulness of the proposed system.
