摘要
基于微网的特点和智能电网对网络通信技术的要求,在搭建风力发电并网实验平台的基础上设计了基于CAN总线和Modbus协议的通信系统并应用于该实验平台。介绍了实验平台的硬件组成和软件设计,详细地阐述了该实验平台的结构和工作原理。为了测试实验平台的功能及可靠性,以三相并网逆变器预测直接功率控制实验为例进行了验证。验证结果表明,以触摸屏为上位机的该实验平台可靠性较高,扩展性较好,可方便地实现多种功能。
According to the characteristics of microgrid and the requirements of smart grid towards network communication technology,a communication system is designed based on CAN bus and Modbus protocol and applied in the experimental platform for grid-connected wind power generation.The structure and principle of the platform are demonstrated in detail in the introduction of the hardware structure and software design of the experimental platform.And in order to test the function and reliability of the platform,an experiment of gridconnected P-DPC is conducted.It is proved that the experimental platform using touchscreen has good reliability and extension and it can achieve various functions easily.
