摘要： A stator for a rotating electrical machine is disclosed, the stator comprising a plurality of stator slots (22) each of which accommodates a plurality of coils (40) of stator windings (18). Radial air gaps (46) are present between the coils of adjacent stator slots as the coils extend out of the stator slots. Insulating means (42, 54, 84) are provided between the coils of a stator slot as the coils extend out of the stator slot. The radial air gaps (46) are defined between the insulating means of the coils of adjacent stator slots. This can allow radial air passages to be formed through the windings, while ensuring sufficient electrical insulation between the coils of a stator slot.

摘要： A rotor (14) for a rotating electrical machine is disclosed. The rotor (14) comprises a plurality of poles (24), each of the poles comprising a plurality of damper slots (30) for damper bars (32). The rotor is designed for use with a machine having a stator (12) with a plurality of stator slots (22) for accommodating stator windings (18). The damper slots (30) in the rotor have a damper slot pitch which is different from a stator slot pitch, and an arrangement which varies from one pole to another. This may lead to a reduction in higher harmonics.

摘要： A separator (10, 60, 65, 100) is disclosed for electrically separating groups of end windings (52) in the stator of a rotating electrical machine. The separator is arranged to provide circumferential air channels (24, 74, 85) through the windings. This can allow air flow to be delivered to inside the windings, thereby cooling the windings more effectively.

摘要： A power generation system is disclosed for supplying power to an electrical grid. The system comprises an engine (1) and an electrical generator (3) coupled to the engine for generating an electrical output. Power electronics (6) are provided for converting the output of the electrical generator into an AC output at the operating frequency of the electrical grid. The engine is operated at a speed which is non-synchronous with the operating frequency of the electrical grid and at which the brake specific fuel consumption of the engine is minimised. The power electronics may also facilitate waste heat recovery and the connection of external energy sources.

摘要： Apparatus for measuring load angle in a synchronous generator is disclosed. The synchronous generator is of a type comprising a main machine, an exciter for exciting the main machine, and a permanent magnet machine for exciting the exciter. The apparatus comprises means for sensing a waveform produced by the permanent magnet machine, means for sensing a waveform produced by the main machine, and means (20) for comparing the waveform produced by the permanent magnet machine with the waveform produced by the main machine to produce a measure of load angle. The measure of load angle may be used to provide a warning of potential pole slip.
