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.

摘要： A renewable energy extraction device, such as a wind turbine generator includes a turbine driving a hydraulic pump and a variable displacement hydraulic motor driving an electrical generator connected directly to an electricity grid. The hydraulic motor employs electronically controlled valves operated to select the net displacement of working chambers of the hydraulic motor on each successive cycle of working chamber volume. In the event of an electric grid fault causing the maximum absorbable torque of the electrical generator to collapse, the electronically controlled valves are controlled to substantially reduce the rate of displacement of working fluid by the hydraulic motor, rapidly reducing the torque exerted on the generator rotor. This has the benefit of avoiding pole slip which could otherwise cause serious damage. During the fault, the rate of displacement of working fluid by the hydraulic motor is controlled to maintain the phase and frequency of rotation of the generator rotor in synchrony with the electricity grid so that electricity generation can resume rapidly once the grid failure is rectified. Excess working fluid displaced by the hydraulic pump is stored in an accumulator. When the maximum amount has been stored pressurised fluid is discharged through a throttle to avoid damage but maintain pressure within the hydraulic transmission so that electricity generation can resume rapidly if the grid failure is rectified. If the fault persists, the turbine blades are feathered to reduce power input and if the fault persists for a further period of time, the energy extraction device shuts down.
摘要翻译：诸如风力涡轮发电机的可再生能源提取装置包括驱动液压泵的涡轮机和驱动直接连接到电网的发电机的可变排量液压马达。液压马达采用电子控制阀，用于在每个连续的工作室容积循环中选择液压马达的工作腔的净位移。在电网故障导致发电机的最大吸收扭矩塌缩的情况下，电子控制阀被控制以显着降低由液压马达产生的工作流体的位移速率，从而迅速减小施加在发电机转子上的扭矩。这有利于避免极滑，否则可能会造成严重损坏。在故障期间，通过控制液压马达的工作流体的位移速度，使发电机转子的相位和频率与电力网同步，使电网故障排除后能够迅速恢复发电。由液压泵移位的多余的工作流体储存在蓄能器中。当最大量已被储存时，加压流体通过节流阀排出以避免损坏，但是保持液压变速器内的压力，从而如果电网故障被纠正，发电可以迅速恢复。如果故障仍然存在，涡轮机叶片会羽化以减少功率输入，如果故障持续一段时间，则能量提取装置关闭。
