摘要
运用非线性模糊滑模变结构控制理论 ,提出了对并联型电能质量调节器来进行模糊滑模变结构控制的设计方法。该控制规律能改善系统电能质量的调节 ,有效地补偿负荷侧谐波电流 ,无功功率和负序电流。仿真结果表明 :该控制规律与常规 PI综合控制相比 ,有较强的实时性和鲁棒性 ,并能有效地改善其暂态稳定性。
By applying nonlinear fuzzy Variable Structure Control (FVSC) theory,a design method of Unified Power Quality Conditioner(UPQC) associated FVSC control is proposed. The control principle can improve the control of Power Quality, strongly compensate for harmonics current, some reactive power and negativesequence current. The results of computer simulation show that compared with the general PI controller, the proposed controller has good real time?robustness and improve transient stability of power system effectively.
