In this article, different electric generator topologies for offshore wind turbines will be reviewed. Although, the most common generator type used in the onshore wind turbines is the doubly-fed induction generator, different generator designs are proposed for large offshore wind turbines, which operate in harsher conditions and are difficult to maintain. Some of these designs are direct-drive permanent magnet generators, hydraulic power take-off systems and superconducting generators.

Integration of Offshore Wind Farm Plants to the Power Grid using an HVDC line Transmission Berkani, Abderrahmane; Pourkeivannour, Siamak; Negadi, Karim; Boumediene, Bachir; Allaoui, Tayeb; Ertan, Hulusi Bülent (2019-01-01) This paper investigates an integration of Offshore Wind Farm Plants with Power Grid Based on an HVDC line Interconnection. Large offshore wind farms are installed in the North Sea area using modern multi-megawatt wind turbines. The Voltage source converter - high voltage direct current VSC-HVDC is a suitable means of integrating such large and distant offshore Wind Power Plants (WPP) which need long submarine cable transmission to the onshore grid. The offshore network then becomes very different from the c...
Hybrid excited synchronous generator design and comparison of direct drive wind turbines Akgemci, Aysel; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019) Various types of electrical generators are used in wind turbines and there is not an agreement on the best generator type. Although, high speed Doubly Fed Induction Generators (DFIGs) are still the most common generator topology utilized in wind turbine systems, there is a trends toward direct-drive Permanent Magnet Synchronous Generators (PMSGs), as they are more efficient and reliable. However, permanent magnets (PMs) induce uncontrollable voltage due to the fixed flux resulting from PM excitation. Conven...
Investigation of inertial support limits in wind turbines and the effects on the power system stability Duymaz, Erencan; Keysan, Ozan; Department of Electrical and Electronics Engineering (2019) In this study, the inertial support implementation is studied for variable speed wind turbines with a full-scale power electronics. To increase the active power as desired, Machine Side Converter is modified with an additional control loop. In the first part of the thesis, active power of the wind turbine is increased to the limits and the maximum achievable active power is found out to be restricted by the wind speed. It is found that the wind turbine can increase its output power by 40% of rated power in ...
Experimental study on power curtailment of three in-line turbines Bartl, Jan; Ostovan, Yasar; Uzol, Oğuz; Saetran, Lars (Elsevier BV; Elsevier BV; 2017-01-20) A dataset of wind tunnel power and wake flow measurements on a setup of three aligned model wind turbines is presented. The power outputs of the three turbines are in good agreement with measurements from a full-scale wind farm of similar inter-turbine spacing. A comparison of the wake flow behind the first row and the second row shows a significantly higher mean velocity loss behind the second row justifying a further power drop from the second to the third row turbine. Curtailing the front row turbine to ...
Numerical simulations of wind turbine wake interactions using actuator line and les models Önel, Hüseyin Can; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2019) Wind is one of the most promising renewable energy resources of the future. After years of optimization studies, Horizontal Axis Wind Turbines shine out as the most efficient type and have been the only model used in large scale commercial wind farms. Layout planning plays an important role in getting the most power out of a wind farm as much as turbine blade design. Most important parameter in this planning phase is the inevitable wake generated by rotors and its impact on other wind turbines which results...
