Wind Turbine Load Optimization Control Strategy Based on LIDAR Feed-Forward Control for Primary Frequency Modulation Process with Pitch Angle Reservation

Because wind power is connected to the grid on a large scale, frequency fluctuation in grid, which defined as system safety risk occurs from time time. According code rules of China, turbines are required be equipped with primary modulation or inertia response control capability, used support safe and stable operation grid. During traditional process turbine, limiting pitch angle reservation generally adopted ensure that reserved energy can released at any change However, method leads loss generation, does not consider coordination between mechanical load characteristics modulation. In this paper, optimization strategy for turbine during process, based LIDAR (light detection ranging) feed forward technology, proposed verified. Through control, incoming speed sensed advance, consequence participate in, actively procedure. wind, instance amplitude turbulence, simultaneously, size adjusted real This kind method, coordinating reduce both ultimate fatigue damage much possible. Finally, without compared studied through simulation. The research results show feed-forward technology effectively loads while supporting grid; especially tower base tilt roll bending moments, reducing proportion will about 4.3% 6.3%, respectively.
