Abstract
Improving operation efficiency has gained attention for wind turbine operation and maintenance. This chapter proposes a method to dynamically calibrate the optimal power-speed curve (OPSC) based on a modified perturbation and observation (P&O) approach to improve power signal feedback (PSF) based maximum power point tracking (MPPT). The detection takes advantage of the P&O approach without detailed modelling. By controlling the wind turbine rotational speed and recording operating data, the maximum power points (MPPs) can be calculated. The OPSC is obtained from the calculated MPPs and applied in PSF control to improve the MPPT efficiency. Simulation and experimental results show that this method can effectively obtain the OPSC for wind turbines to achieve MPPT.
