基于BX3100 PLC的风电变流器通信系统设计

Design of communication system of wind power converter based on BX3100 PLC

介绍了风力发电中主控系统的作用、特点以及主控系统的通信模式。根据实际需要,采用RS232串口通信,选取BX3100PLC作为Profibus-DP从站设计了风电变流器通信系统,实现与主控系统的Profibus总线通信。论述了系统的原理和程序流程,给出了测试结果。

The functions and the features of the master control system in wind power generation system were introduced,and the communication mode of the master control system was described.According to the requirement of the practical project,the communication system of the wind power converter was designed,in which the RS232 serial port communication was adopted,and the BX3100 PLC was selected and used as the Profibus-DP slave station.The Profibus bus communication between the wind power converter and the master control system were realized by the communication system.The principle and the program flow of the system were expounded,and the test results were given.
