Abstract

The range of offshore wind speed variation is higher than onshore with high frequent of wind gusts. This paper propose an efficient utilization system for offshore wind energy generation and transmission to the power grid. Pitch controlled wind turbines are modelled and pitch controller is developed to track the available wind power and to keep the generated power at its maximum even during wind gust incidence. Secondly, for transmission of the generated wind power to the grid, voltage-source converter (VSC) stations with High voltage direct current (HVDC) technology is used to minimize the transmission losses. The results shows that the proposed pitch controller is stable and capable to capture the maximum wind power. Also the proposed scheme ((VSC-HVDC-VSC) succeeds to export the active power generated in offshore wind farm to the grid using four quadrants PWM-VSC converter by controlling the DC voltage.
