Abstract:

推导了向无源网络供电的电压源换流器高压直流输电(VSC-HVDC)系统整流侧和逆变侧的离散数学模型。针对传统的基于PI调节器的双闭环控制策略存在控制结构复杂、PI参数较多且整定困难和难以实现多目标优化控制等缺点,根据系统离散数学模型,提出基于模型预测控制的VSC-HVDC系统整流侧直接功率控制和逆变侧直接交流电压控制策略。详细描述了所提控制策略的实现过程,提出权重系数的选取方法,并结合仿真实例进行详细说明及验证,克服了权重系数选择的主观性和盲目性。在PSCAD/EMTDC中搭建了向无源网络供电的VSC-HVDC系统,对整流侧无功指令突增、直流电压指令突增以及逆变侧空载、带线性负载、带非线性负载、负载突变、交流电压抬升、模型参数出现偏差和逆变侧交流故障等情况进行了仿真研究。仿真结果表明,所设计的控制器具有良好的稳态性能和动态性能,且模型参数鲁棒性较好,能在各种情况下向无源网络提供高品质电能。
