Abstract
U svijetu su sve veće potrebe za obnovljivim izvorima energije. Energija vjetra je oblik obnovljivog izvora energije s najbržim porastom po ukupno instaliranoj snazi u svijetu. Vjetar na moru je ustaljeniji, stoga se more čini kao odlično mjesto za izgradnju vjetroelektrana. Uz sve to, upravljanje plutajućim vjetroagregatim nije lagano zbog morskih mjena i energije valova i drugog. U radu je projektiran linearizirani kompenzator njihanja koji dovoljno dobro ispravlja ponašanje sustava u odnosu na poremećaje izazvane valovima. Korištenje alata poput MATLAB-a, FAST-a i ostalih omogućuju lakše lineariziranje modela. Nakon linearizacije određeni su prirodna frekvencija i relativni koeficijent prigušenja. Pomoću prirodne frekvencije i relativnog koeficijenta prigušenja projektiran je kompenzator njihanja s obzirom na željeno povećanje prigušenja sustava. Adaptaciju parametara kompenzatora moguće je ostvariti korištenjem brzine vjetra ili kuta zakreta lopatica. Projektirani kompenzator dodatno povećava prigušenje sustava, ali zbog ograničenja sustava, ograničava se mogućnost prigušenja. Stoga se samo djelomično mogu umanjiti oscilacije platforme.
Abstract (english)
Land-based wind power has been one of the world’s fastest growing energy source. Offshore wind is more constant and that is why it looks like a great place to build a wind farm. On the other hand, it is not easy to design a controller for an offshore wind turbine since waves have varying amplitude and frequency resulting with destabilised behaviour of the control system. To design a platform nodding compensator it is necessary to linearize platform pitch equation. It is very hard to do it manual. That’s why using MATLAB and FAST tools can be handful. These tools linearize model which is important for defining natural frequency and system damping. These parameters determine constant of the nodding compensator. Respective constant reflects on pitch movement which reflects on the platform pitch motion. Existing limitation is a maximum blade pitch rate which can not exceed 8 degrees per second. This limits platform pitch damping resulting with control system which only partially improves platform pitch movement.
