In this article is presented the modal analysis of the blade in pitch regulated horizontal axis wind turbine. The structural model of the blade is modelled as beam elements in MSC Nastran. As a result of modal analysis are received the mode shapes with the frequencies of blade vibration. Than is made attempt to describe the influence of the aerodynamic damping phenomena on dynamics of the blade. To...
Artykuł porusza tematykę sterowania mocą w elektrowni wiatrowej pracującej na sieć elektroenergetyczną. Zaprezentowano aproksymację funkcji opisującej charakterystykę turbiny wiatrowej przy pomocy sieci neuronowej, w celu określenia optymalnego sterowania kątem położenia łopat w funkcji prędkości wiatru pod względem maksymalizacji produkowanej energii. Na tle optymalnej charakterystyki zaprezentowano...
