K. Rama Lingeswara Prasad, K. Chandra Sekhar . Variable Structure Controller for Generator Side Converter of Variable Speed PMSG Wind Energy Conversion System. International Journal of Computer Applications. 67, 18 ( April 2013), 28-33. DOI=10.5120/11497-7208
Abstract
This paper presents a novel control strategy based on variable structure theory (VST) for the generator side converter to regulate the dc link voltage of a direct driven PMSG wind energy conversion system (WECS). The validity of the technique is theoretically analyzed, and the design procedure is presented. The primary merit of the proposed technique is that it does not require an anemometer or prior knowledge of a system, but has an accurate and fast dynamic response to wind speed fluctuations. Modeling of Wind turbine, PMSG, controlling of generator side switch mode converter and Simulation results are presented. Simulation is done in MATLAB/POWERSYSTEM environment.
