Wind driven generator control system

The invention discloses a wind driven generator control system based on DSP+MCU+FPGA, which is suitable for controlling a double-fed wind driven generator converter of 1.5MW. A digital signal processor DSP utilizes strong data arithmetic capability to realize the function of large quantity data operation of the converter; a microprogrammed computer unit MCU utilizes abundant internal resource to realize the protection and communication functions of the converter; a filed programmable gate array FPGA utilizes abundant I/O pins and convenient expandability to realize the functions of PWM signal output and switch in-out signal extension management of the converter. The MCU and the FPGA are communicated by a local bus interface, and a watchdog function is designed to monitor mutual operation state. The design fully satisfies the requirements of the current wind driven generator converter, and greatly improves the expandability and the reliability of the converter.
