This thesis focuses on developing a hardware-in-the-loop wind energy conversion system emulator. In addition, software for simulating the hardware-in-the-loop system is developed. The thesis describes how a wind turbine model is developed by controlling an induction motor to emulate wind turbine shaft. Control of the overall hardware-in-the-loop system for achieving an accurate medium for wind energy conversion system emulation is explained. The software uses the same model for the wind turbine as the HIL system. Modelling of the generator and gearbox is fairly straightforward. However, back-to-back converters which facilitate connection of the system to the grid are highly nonlinear elements. A novel neural network based model is developed for these converters by performing experiments on them and the accuracy of the model is investigated. Finally, the software developed is used to investigate problems of islanding operation so that energy quality of the local loads can be maintained in this operation.

A Hardware in the loop simulator development for wind energy conversion systems
Pourkeivannour, Siamak; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2019)
In this thesis a wind turbine emulator is developed to replicate the mechanical and electrical behavior of a real wind energy conversion system. A scaling down algorithm is developed to scale down the mechanical behavior of a real wind energy conversion system to a laboratory scale wind turbine emulator. A user interface software is developed to be used as a supervisory control and data acquisition system for the wind turbine emulator in LABVIEW environment. The accuracy of the scaling down algorithm is ver...
Validation of Parallel WRF Downscaling Methodology using OpenFOAM
Leblebici, Engin; Tuncer, İsmail Hakkı (2017-06-26)
The main objective of this study is to obtain real-time atmospheric flow solutions using open source CFD solver OpenFOAM coupled with Numerical Weather Prediction (NWP) model; Weather Research Forecast (WRF). NWP can take moist convection, land surface parameterization, atmospheric boundary layer physics into account, but wind flow features finer than 1 km aren't captured by the turbulence physics of such models. CFD simulations, however, have proved to be useful at capturing the detail...
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 ...
Micro-siting of wind turbines using navier-stokes solutions coupled with a numerical weather prediction model
Ahmet, Gökhan; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2014)
High resolution atmospheric flow solutions are obtained with an in-house, parallelized 3 dimensional Navier-Stokes solver, HYP3D coupled with a meso-scale meteorological weather prediction software, WRF, and the wind potential of a specified terrain is assessed based on long term atmospheric flow solutions. Body-fitted grids are employed to discretize the complex terrain of interest in HYP3D. In the study, high resolution (1.5 arcsec) topographical data is used to discretize the specified terrain. In HYP3D ...
Switch mode converter based damping of PWM converter with LCLtype filter for grid interface of renewable energy systems /
Usluer, Sebahattin Nadir; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2014)
This thesis involves design and simulation for switch mode converter based damping of three-phase LCL-filtered PWM converter widely used for grid-interface of renewable energy systems. The study involves the resonance damping of high power voltage source converters connected to the grid via LCL filters. The design is verified by means of detailed computer simulations. The study considers eliminating the resonant harmonics which results in overvoltage/current stresses and leads to the failure of the converte...
