摘　　要：对能馈式供电变流器多模块并联拓扑进行分析,提出一种基于CANopen的多模块并联方案.通过对系统原理和CANopen协议分析,发现CANopen网络能很好满足系统安全运行及控制性能要求;根据变流器控制原理选取了系统网络控制量,并设计了基于CANopen的系统运行机制;通过建立系统的网络控制模型,分析了网络时延对系统控制性能影响,然后确定了系统采样周期的理想选取范围;最后,通过仿真和试验证明基于CANopen的多模块并联能馈式供电系统网络控制方案的可行性、稳定性和可靠性.The energy reclaiming supply system using multi-paralleled topology is analyzed, and multi- paralleled scheme based on CANopen is proposed. According to the system principle and CANopen protocol,it can be proved that CANopen network can meet the safe operation and control performance of the system. According to the principle of the converter, the system control data through the network is selected, and the system operating mechanism based on CANopen is designed. After the networked control system modelling, the impact of control performance about networked delay is analyzed, and then the ideal sampling period range is determined. Finally, simulation and test prove the scheme of multi- module parallel energy reclaiming supply networked control system is feasible, stable and reliable.
