Title: Method of synchronising a generator drive with an alternating current electrical network
Inventor: CALDWELL NIALL
IPC: F03D11/02
Filed: 2012-06-05
Abstract: 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.
