Large parallel network wind turbines generate power by transfer torsional power, which is captured by wind shroud and accelerated by driving chain, to electric machine rotor. The drive system of variable speed wind turbine mostly uses flexible connection. That kind of connection adjusts exciting current and operating condition when wind speed and rotary speed change. Thus, it is one of the main reasons...
Pitch-regulated mechanism servo of wind turbine system is a slow time-variable nonlinear system. According to the requirement of the 1 MW wind turbine with variable speed and constant frequency, the parameters of its PID controller need to be learned or adjusted at real time. Therefore, we design this neural net PID controller based on the Hebbina supervised learning algorithm to realize the self-study...
