Hi all, I am currently in my last year of study at University and I am working on my final year project for a braking system for a wind turbine generator.
I am not actually building a working turbine as the wind power and rotational speed will be simulated in a lab. I will be using a 24v DC motor as the generator (I have others at my disposal) and will be designing and building my own circuit to control the rotary speed.
I am looking for advice on whether to go for regenerative braking or an H bridge design or a DC injection system for the DC motor brake (mainly looking at the latter two). The aim of the braking system is to cap the speed of the wind turbine and not to brake the motor to a full stop, what feed back system is best for this? Also, is it feasible to design a control system that is capable of running off the power generated by the turbine?
You advice would be much appreciated, thanks in advance.
