提出了一种静止无功补偿器(static var compensator,SVC)的不平衡补偿方法。针对不平衡情况下的功率补偿需求,提出了基于佛布迪(fryze-buchholz-depenbrock,FBD)算法的等效电纳检测方法,有效减小了系统的计算量;为了提高SVC的补偿性能,提出了一种开环和闭环复合控制方法,并利用单纯形算法对控制参数进行动态调整,提高了系统的鲁棒性,大大提高了SVC的补偿精度和补偿性能,实现了三相系统的功率平衡。最后,仿真和实验验证了所提出方法的有效性和正确性。
An imbalance compensation method for static var compensator (SVC) is proposed. In order to meet the demand of power compensation under unbalanced conditions, an equivalent susceptance detection method based on fryze-buchholz-depenbrock (FBD) algorithm is proposed, which can effectively reduce the computational complexity. In order to improve the compensation performance of SVC, An open-loop and closed-loop composite control method is proposed, and the simplex algorithm is used to dynamically adjust the control parameters to improve the robustness of the system and greatly improve the compensation accuracy and compensation performance of the SVC. The power of the three-phase system balance. Finally, the validity and correctness of the proposed method are verified by simulation and experiment.
