Abstract:

bstract: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.

Key words: wind power generation, wind power converter, programmable logic controller (PLC), Profibus, RS232 serial port
