With the development of offshore wind power generation, large-capacity medium-voltage wind turbine becomes the development trend. In this paper, the cascaded multi-cell topology with four-quadrant operation capacity is applied to medium-voltage wind power converters, which consist of a large number of switching devices, so it is essential to improve the converter's fault-tolerant ability. Once the...
DC voltage control and power distribution are significant requirements for multi-terminal HVDC control system. The common voltage droop control has the drawback of failing to keep the dc voltage at a fixed value if active power is fluctuating, and voltage margin method actually controls dc voltage only by one converter at a time. A novel control strategy-Coordinated DC Voltage Control-is thus proposed...
Offshore wind power converter is usually packed in a closed cabinet equipped with water cooling to meet the moisture and salt spray prevention requirements. When a sudden dip of wind speed happens, the generated power will reduce significantly, making power semiconductor device and cooling water's temperature reduced quickly. While the air temperature inside cabinet decreases slowly. Thus, the water-cooling...
This paper presents a wind turbine concept based on a dual-stator-single-rotor (or sandwich-typed) PMSG and a novel converter. First, the structure of the sandwich-typed PMSG is explained. Then, according to the principle of the PMSG, a novel converter topology is proposed. Finally, a detailed direct drive wind turbine model based on the converter and the PMSG is built in the Matlab/Simulink. Thorough...
A novel topology of wind power generator system based on Z-source dc/dc converter is presented in this paper. With wide dc output voltage range, this topology is suitable for series dc wind farm. The operation characteristic and control method of Z-source dc/dc converter are analyzed. Simulation results of 3 series wind generators show that the wind farm interconnected with this topology is feasible.
Offshore wind energy has become an increasingly attractive option due to the enormous energy potential associated with the vast offshore areas. The investigation of offshore wind turbines characterized by large-scale involves high performance wind turbine simulator, especially in the case of the development of optimal control strategy. Because of the increasing rotor size and the spatial load variations...
