Generator

Electrical generator

A rotating electrical machine includes a stator and a rotor arranged to rotate inside the stator. The rotor includes a plurality of permanent magnets arranged to produce a radial magnetic flux in an airgap between the rotor and the stator. The machine also includes a stationary excitation coil. The rotor also includes a plurality of low reluctance elements. A current through the stationary excitation coil causes a magnetic flux to be established in a magnetic flux path which passes into the rotor through a first low reluctance element and out of the rotor through a second low reluctance element, which magnetic flux combines with the radial magnetic flux produced by the permanent magnets in the airgap. This arrangement can allow control of the field within a permanent magnet radial flux machine.

A power generation system is disclosed for supplying power to an electrical grid. The system comprises a synchronous machine and coupling means for coupling the synchronous machine to a prime mover. Control means are provided to control the system such that the system is selectively operable in two modes. In the first mode, the synchronous machine is coupled to the prime mover and acts as a synchronous generator to supply power to the grid. In the second mode the synchronous machine is decoupled from the prime mover and acts as a synchronous condenser. This can allow parameters of the grid, such as power factor and voltage, to be adjusted.
