Abstract:

对于三相逆变器并联系统,下垂控制是一种有效的控制算法,它可以确保各并联逆变器对系统负载功率的均分,并具有无互连线分布式控制的优点。而对于三相电压型逆变器,新兴的有限控制集模型预测控制算法(finitecontrolsetmodelpredictivecontrol,FCS-MPC)具有系统动态响应快、处理系统约束灵活等优势。将逆变器并联系统的下垂控制与三相电压型逆变器的模型预测控制结合起来,由下垂控制器提供模型预测控制器的参考电压信号,以并联逆变器输出电压对参考电压的跟踪误差构建模型预测控制器的优化性能函数,实现了三相电压型逆变器并联系统的无互连线模型预测控制。仿真及实验结果表明:所构建的无互连线模型预测控制器在三相电压型逆变器并联系统由空载投入负载、负载突变及某一并联逆变器切除等工况下均能有效运行,且与传统的逆变器并联系统三环控制器相比,显著地改善了三相逆变器并联系统的均流性能。
