Variable speed constant frequency wind power generation system operation and control research source code based on TMS320F2812

The research object is an AC excitation variable speed constant frequency wind power generation system using a doubly-fed asynchronous generator. Mainly researching the complete basic theory and key technologies of AC excitation variable speed constant frequency wind power generation, vector conversion control and P and Q decoupling control technology of AC excitation generators , maximum wind energy tracking control of variable speed constant frequency generators, and converters for AC excitation Research and coordinate and comprehensive control of various parts of AC excitation variable speed constant frequency wind power generation system. The AC excitation variable speed constant frequency wind power generation experimental system was developed using TI's TMS320F2812 to complete the maximum wind energy tracking control experiment.

In view of the energy flow characteristics of the doubly-fed asynchronous generator rotor, a dual PWM converter with bidirectional energy flow function based on TI's DSP control was studied and designed. The control of the dual PWM converter, especially the grid-side converter, was discussed. method. Using the electromagnetic transient PSCAD/EMTDC software, a wind turbine simulation model was established. This simulation system was used to conduct simulation research on the generator grid-connected control P , Q decoupling control, and maximum wind energy tracking control.
