摘　　要：针对大功率变频器系统的并联结构,提出了一种高实时高同步的光纤通信方案。飞速传输方式保证各控制器间通信具备较低延时;时钟同步算法补偿从控制器与主控制器的时钟偏差,保证系统内所有控制器的输出信号高度同步,减小环流及其危害。当系统需要降额运行或者发生严重故障时,所提方案能够及时响应主动或被动改变光纤通信网络中控制器的数量,为大功率变频器系统提供灵活的通信解决方案。实验验证了所提光纤通信方案的有效性。Based on the parallel structure of high-power converter system,a high real-time and high synchronization optical-fiber communication scheme was proposed.The on-fly transmission ensures that the communication between the controllers has a low delay,and the clock synchronization algorithm compensates the time-difference between the master-controller and slave-controller,which ensure clock synchronization of all the controllers in the system to reduce circulation and its harm.When the system needs to run down or has a serious fault,the system could respond in time by changing the number of slave controllers in the optical-fiber communication network actively or passively,which provided flexible communication solutions for high power converter systems.The experimental results show that the proposed optical-fiber communication scheme is effective.
