TTCAN在风力发电控制系统中的应用

基于TTCAN构建风力发电控制系统各控制器模块问CAN总线通信，提高总线利用率，避免总线冲突。同时辅以双冗余措施，试图满足控制系统高可靠性、高实时性要求。本文详细阐述控制系统TTCAN软件实现过程以及总线冗余实现过程，并设计通过计数的方式监视总线运行情况。实验结果表明．冗余TTCAN方式能很好的满足系统控制需求。

Application of Time-Triggered CAN in Wind Power Control System

The CAN bus communication between controller modules in the wind power control system is constructed by time-triggered CAN, trying to improve bus utilization and avoid bus conflicts. At the same time, combined with dual-redundancy, this way can meet the high reliability, high real-time requirements of the control system. This paper detailed the I-rCAN software process in the control system as well as the realization of redundant bus, and design the way of counting to monitor the operation of the bus. At last, the experimental results proved that this way is a good way to meet the needs of system control.
