摘　　要：传统的UPS无互联线并联下垂特性控制是采用频率下垂和幅度下垂来调节输出电压。这种控制方法虽然是有效的,但是它容易导致系统正反馈。文中提出了一种基于神经网络解耦控制的下垂特性控制方案。这种新的控制方法能有效地克服传统下垂特性控制的局限性。由仿真结果得,该方案下逆变电源均分负载电流的效果好,而且系统动态响应性能高。The control scheme of the traditional droop characteristic in the parallel operation of UPS without control interconnection is based on frequency-droop and amplitude-droop scheme to control the output voltage This control scheme is effective, but it may introduce positive feedback. This paper presents a new droop characteristic scheme based on neural network decoupled control. The new control scheme can overcome the defect of traditional droop characteristic. According to the simulation results, the inverters in the parallel connection realize good performance in load current sharing and faster system dynamic response.
