Hi, my query is regarding pitch increase/decrease rates.
I’ve read that the max pitch rate for 5 MW turbine is 8 degrees/sec. I’m working on a 1.5MW turbine model and I want to choose a value that is close to reality. What would the value be? (considering contemporary wind turbine control systems) Would 5-6 degrees/sec be a reasonable assumption?
Also, I’ve read elsewhere (not in our forum) that there could be different limits for pitch increments and decrements. It was mentioned that the limit for pitch increments was 4 degrees/sec and for decrements, it was a mere 0.7 degrees/sec. Is there such a vast difference in both usually?
Edit: What is the general time lag between the pitch control signal and the physical implementation of the signal?
