Abstract
A power system includes a synchronous electrical generator having a rotor driven by a shaft; a permanent magnet signaling generator, coupled to the shaft; and an angle computation unit configured to calculate a rotor angle or load angle based on a voltage from the permanent magnet signaling generator and a voltage from the synchronous electrical generator.
Claims15
A power system, comprising:
- a synchronous electrical generator having a rotor driven by a shaft;
- a permanent magnet signalling generator, coupled to the shaft;
- and
- an angle computation unit configured to calculate a rotor angle and/or load angle based on a voltage from the permanent magnet signalling generator and a voltage from the synchronous electrical generator.
A method of determining a rotor angle or load angle in a power system comprising synchronous electrical generator, the method comprising calculating the rotor angle or load angle based upon a voltage from a permanent magnet signalling generator coupled to a rotor shaft of the synchronous electrical generator.
