The invention relates to a wind energy system with hydraulic energy transmission with non-symmetric actuation. The non-symmetric actuation is caused by valve control and mechanical means for controlling the actuation of the pistons. A cylinder unit is provided comprising a drive unit and an output unit associated with two hydraulic connections. The drive and the output unit comprise a minimum of two cylinders, in which pistons are reciprocating. Some of the cylinders can be switched off during low wind speeds. The cylinders communicate with a low pressure manifold and a high pressure manifold. These manifolds are part of the hydraulic connections. Use of the fluid-working machine as transmission in wind energy systems increases the overall economical efficiency.
A wind energy system comprising a fluid-working machine with non-symmetric actuation acting as a transmission, the fluid-working machine comprising working chambers that are switchable to a predetermined state by a pressure difference opposite to the pressure difference during operation of the working chambers.
A wind energy system comprising a fluid-working machine with non-symmetric actuation acting as a transmission, the fluid-working machine comprising working chambers that are switchable to a predetermined state by a pressure difference opposite to the pressure difference during operation of the working chambers, whereby said fluid-working machine receives a rotational force and outputs the rotational force to a second device.
A method for operating a wind energy system comprising
