Modeling Hydraulic Accumulators for use in Wind Turbines [PDF]
Linköping Electronic Conference Proceedings, 2013 One of the major challenges in numerical simulation of hydraulic systems, is the long computation times of accumulators. In wind power applications, the accumulators must provide necessary hydraulic energy during emergency stops, while the weight of hydraulic equipment must be minimized.

Modeling and Simulation of Hydraulic Wind Turbine
Applied Mechanics and Materials, 2012 The wind energy can be transferred through an intermediate medium such as hydraulic fluids. In this paper a hydraulic system is utilized to transfer the wind energy from a wind turbine to a synchronous generator. A close loop hydraulic transfer system with fixed displacement pump and variable displacement motor is introduced and the mathematical model ...
