摘要：

针对分布式控制的并联逆变器系统（PCS）的环流问题，提出一种快速分布式主从控制方法.这种控制方法是依靠高速通讯总线传输实时的电流指令数据，取代了传统电流有效值指令，实现主机和从机的均流控制.由于从机的电流信号在通讯总线传输过程中延时，所以PCS系统存在一定环流.将信号延时作为输入变量，PCS系统的环流作为输出变量，构建数学模型.基于该数学模型的分析，可以得出结论：通过调整控制器参数可以有效限制PCS系统环流.理论分析和实验结果表明这种分布式控制方法可以有效抑制PCS系统的各套逆变器之间的环流.
Abstract:

Considering circulating currentissue in parallel convertor systems (PCSs), a novel high speed distributed master-slave control method is proposed. In this proposed method, real-time current signals, instead of current RMS signals, were transmitted between master convertor and slave one by the high-speed communication bus, and currents of master and slave convertors were balanced in PCSs. Because the real-time current signals transmitted into the slave ones were delayed by the transmission bus, circulating current existed in the PCSs. A mathematical model was built by taking the current signal delay as the input variable and taking the circulating current as the output variable. The analysis of the mathematical model concludes that circulating current is limited by regulating the parameters of the control loops. Theoretical analysisand experimental results indicate that circulating current in PCS is limited by the high speed distributed master-slave control method.
