摘要:
Methods, systems and apparatuses including systems and methods that can be used for operating a wind turbine including in power generation and regeneration modes are disclosed. According to one example, a method is disclosed that can include adjusting a power split transmission coupling to transfer substantially all torque from a turbine rotor to a generator by working a hydraulic fluid, wherein the generator converts mechanical power to electrical power, diverting the hydraulic fluid at high pressure from the power split transmission coupling in response to the electrical power produced by the generator exceeding a threshold to maintain the electrical power produced by the generator at or below the threshold; storing the hydraulic fluid diverted from the power split transmission coupling under high pressure in a storage vessel; and introducing the hydraulic fluid stored at high pressure to a hydraulic motor in response to the generator producing below threshold electrical power, the hydraulic motor operatively coupled to the generator and configured to transmit mechanical power to the generator for electrical power generation.

A fluid working machine 11, 12 is provided with a cylinder 19, a piston 18 having an inner passage 55, 56 where working fluid is introduced from a working chamber 20, a roller 21 rotatably engaged to the piston 18, and a cam 22 rotating in contact with the roller 21. On an engagement surface of the piston 18 engaging with the roller 21, a groove 60 is formed to introduce the working fluid from the working chamber via the inner passage 55, 56. The groove 60 includes an annular groove portion 61 and a communication groove portion 62 formed along the rotational direction of the roller 21 to traverse the annular groove portion 61. The inner passage 55, 56 opens to the communication groove portion 62.
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.
