Conventional wind power plants employ a variable speed gearbox to run a generator housed on top of a tower. A new topology can remove some of the weight from the tower and centralize the wind power generation. This new topology uses a hydraulic wind power transfer system to connect several wind turbines to the generation unit. This paper demonstrates a(More)
Hydraulic wind turbines are highly nonlinear and work severely under variable disturbances such as load on the generators and the wind speed. For further analysis control implementation on these types of systems a suitable linearized model is needed. Due to the disturbances, the system has a wide range of operating points. Therefore, linearized models on(More)
Hydraulic circuits can transfer remarkable amounts of energy in the desired direction without taking large space. To implement this technology for harvesting the energy of wind appropriately, models of the system are required. Hydraulic wind power technology has the benefits of eliminating expensive and bulky variable ratio gearbox and its costly(More)

The structure of hydraulic wind power plants involves one or several high-pressure hydraulic pumps and a central power generation unit to combine the energy from wind turbines. As the wind speed drops, the energy generation may not be significant enough to run the main generator. Therefore, an auxiliary generator generates power for the storage devices. The(More)
Abstract— High-pressure hydraulic systems have shown low efficiency in wind power transfer when interface a single-turbine to a ground-level generator. This paper demonstrates that using a central generation unit for a group of wind turbines and transferring the power of each turbine through hydraulic system increases the efficiency of overall system by 17%(More)
