摘要： It is intended to provide a power generating apparatus of renewable energy type and an operation method of the power generating apparatus, which can achieve both variable speed operation and grid connection without a frequency converting circuit and which uses a hydraulic transmission. In the power generating apparatus of renewable energy type 1, renewable energy received via a blade 4 is transmitted to a synchronous generator 20 via a rotating shaft 8 and a hydraulic transmission 10. The synchronous generator 20 is driven by a hydraulic motor 14 of the hydraulic transmission 10 to generate power. The synchronous generator 20 is connected to a grid without a frequency converting circuit and the power generated by the synchronous generator 20 is supplied to the grid 50. The power generating apparatus 1 is also provided with a transmission controller 40 which controls the hydraulic transmission 10. The transmission controller 40 controls the hydraulic transmission 10 in a normal operation mode to adjust displacement of each of a hydraulic pump 12 and the hydraulic motor 14 such that the rotating shaft 8 rotates at a rotational speed that is variable with respect to flow speed of the renewable energy while keeping a rotational speed of the synchronous generator 20 at a synchronous speed based on frequency of the grid 50 during normal operation of the power generating apparatus.

摘要： A wind turbine generator (100), or other energy extraction device, has a hydraulic circuit comprising a hydraulic pump (129) driven by a rotating shaft (125) and a hydraulic motor (131) driving an electricity generator (157), or other load. A high pressure manifold (133) extending between the pump and motor is in communication with an accumulator (145, 147, 149). A controller receives a control signal and regulates the displacement of working fluid by the hydraulic pump and the hydraulic motor relative to each other. Thus, power input through the rotating shaft and output to the load can be decoupled for at least a period of time and the energy output of energy extraction device can be varied, for example to smooth the total power output to an electricity grid (101), without compromising power input. A group of energy extraction devices can be controlled in concert to maximise power input while providing smooth power output. Individual electricity generators in different energy extraction devices can be switched on and off in concert to provide smooth power output while benefiting from the reduced energy losses that can be obtained by switching off electricity generators where possible.

摘要： A wind turbine generator, or other energy extraction device, has a hydraulic circuit comprising a hydraulic pump driven by a rotating shaft and a hydraulic motor driving an electricity generator. When the electricity generator is switched off, it executes one or more pumping cycles to pressurise the high pressure manifold and therefore recover angular kinetic energy from the electricity generator rotor which can later be used to reaccelerate the electricity generator rotor to the correct operating speed for an electricity grid. Overall energy efficiency is increased and the minimum operating high pressure manifold pressure may be reduced as a result.
