摘要： A hydraulic transmission comprising a variable displacement pump and motor, at least one having cylinders having valves which are controllable on each cycle of cylinder working volume to determine the net displacement of working fluid by the cylinder. The transmission has a valve control module which determines a displacement of the pump and the motor by specifying a displacement demand. The pump and/or motor valve control module determine the frequency of intensity peaks in the frequency spectrum of the pattern of cylinders carrying out active and inactive cycles of cylinder working volume using a first procedure and, if these will fall within disallowed frequency bands including the resonant frequency of components with which the transmission is in mechanical communication, the displacement demand, or another input, is periodically modified to suppress generation of those frequencies. The hydraulic transmission is useful for example in a wind turbine generator, or a vehicle.

摘要： A hydraulic apparatus has a plurality of pump modules each of which is formed by a plurality of working chambers having a common high pressure manifold. A connecting circuit switchably connects pump modules to first and second hydraulic circuit portions to allocate capacity as first and second demands for hydraulic fluid vary. In an apparatus which may have two or more connecting circuit outputs, valves may be controlled or working chamber pumping cycles made inactive to facilitate the reallocation of a pump module from one output to another, and a control strategy addresses pump module allocation when the demands for hydraulic fluid exceed available capacity.

摘要： A method of synchronising a generator drive with an alternating current electrical network. A generator is driven by a hydraulic motor having a hydraulic input coupled to a source of pressurised hydraulic fluid and one or more working chambers of cyclically varying volume for receiving and depressurising discrete portions of received hydraulic fluid, the volume of pressurised hydraulic fluid received by each working chamber being selectable for each cycle of working chamber volume, the generator drive comprising a controller which selects the volume of the pressurised hydraulic fluid which is received by each working chamber on each cycle of working chamber volume to thereby drive the generator. The controller controls the rate of receipt and depressurisation of hydraulic fluid by the hydraulic motor to match the frequency, and then the phase, of the output from the electrical generator with an electrical network. The procedure enables synchronisation to take place rapidly. The motor can be part of the hydraulic transmission of a wind turbine generator or other renewable energy generation device and receive pressurised fluid from a hydraulic pump, driven by a rotor, through a pressurised fluid line. When controlling the displacement of the hydraulic motor, the pressure variations in the pressurised fluid line are rejected. Motor displacement is also regulated to avoid underpressure in the pressurised fluid line. During synchronisation the pitch of the turbine blades and the displacement of the hydraulic pump are also regulated. The renewable energy generation device can therefore be started up efficiently and reliably.
摘要翻译：一种使发电机驱动器与交流电网同步的方法。发电机由具有耦合到加压液压流体源的液压输入和循环变化体积的一个或多个工作室的液压马达驱动，用于接收和减压接收到的液压流体的离散部分，每个所述发电机驱动器包括控制器，所述控制器选择在每个工作室容积循环中由每个工作室容纳的加压液压流体积，从而驱动所述发电机。控制器通过液压马达控制液压流体的接收和减压速率，以匹配来自发电机的输出与电网的频率，然后相位相位。该过程使得能够快速进行同步。电动机可以是风力涡轮发电机或其他可再生能源发电装置的液压变速器的一部分，并且通过加压流体管线从转子驱动的液压泵接收加压流体。当控制液压马达的排量时，加压流体管路中的压力变化被排除。电动机位移也被调节以避免加压流体管线中的负压。在同步期间，涡轮叶片的间距和液压泵的位移也被调节。因此，能够高效可靠地起动可再生能源发电装置。
