    ENERGY STORAGE SYSTEM FOR HYDRAULIC WIND ENERGY TRANSFERS
    (Office of the Vice Chancellor for Research, 2012-04-13) Hamzehlouia, Sina; Izadian, Afshin
    Gearless hydraulic transmissions are considered noble candidates for wind power transfer systems. Hydraulic wind power transfer systems allow collecting the energy of multiple wind turbines into one generation unit. Fur-thermore, elimination of the gearbox as a bulky and expensive to maintain component reduces the cost of energy conversion. The hydraulically con-nected harvesting systems require controllers to maintain the frequency and generate the required power. However, the intermittent nature of wind im-poses fluctuation on the amount of generated wind power and on the fre-quency of the output voltage. This poster introduces a wind energy storage technique through a hydraulically connected wind power transfer system. The simulation results demonstrate the successful operation of the storage to maintain the fluid in the system to keep the generator speed at a prede-termined value. The system is mathematically modeled and the control sys-tem is derived.
