| dc.title | Modelling and analysis of type 4 wind turbine generator with energy storage system | en_US |
| dcterms.abstract | The development of wind energy conversion system has been rapid in the past years for the goal of net zero. Under the support of various stakeholders, more and more onshore and offshore wind farm was designed and put into operation. In offshore wind farm, the state-ofÂ-the-art topologies using are type 4 wind turbines, which enables a full control on rotor operation to achieve the maximum power point with reference wind speed. With the major benefits of the topology as well as low maintenance requirement, type 4 wind turbine is widely adopted in modern wind farms. | en_US |
| dcterms.abstract | Indeed, the operation of the type 4 wind turbine is prone to the abnormal events in power grid. During the presence of grid events, the disturbance may propagate and exert on the wind turbines and creating electrical and mechanical stress to the components of the wind turbine. These disturbance and stress would result in reducing the life span of the wind turbine. | en_US |
| dcterms.abstract | To study the behavior of type 4 wind turbine under various gird events, this research suggested a simple model to couple the OpenFAST, a software developed by National Renewable Energy Laboratory (NREL) for simulation the mechanical properties of wind turbine, with Simulink. The Simulink model provides a more advanced electrical model to couple the mechanical model in OpenFAST to study the electro-mechanical reaction of the wind turbine under grid events. | en_US |
| dcterms.abstract | The electro-mechanical behavior of the type 4 wind turbine under grid events are studied. In this research, the grid events of overvoltage, undervoltage and 3-phase-to-earth fault is applied to the power system and the respond of the type 4 wind turbine is observed. Energy storage system (ESS) composed with supercapacitor are implemented to the system to study the behavior of the system. | en_US |
| dcterms.abstract | The result demonstrated the electro-mechanical behavior of the wind turbine under grid events. The fluctuation in grid voltage created disturbance to the wind turbine, which the generator speed oscillates from a large disturbance. The implementation of energy storage system able to mitigate the rise of DC link voltage but not for the grid stability. | en_US |
