312-11 Generators, Torque, Angle and Synchronizing EPP (1 CEH)

A power plant generator consists of a rotating magnetic field on a rotor inside armature windings on the generator's stator. The turning electromagnetic rotor causes lines of flux to cut through the coils in the stator. Voltage is induced in these coils, with current flowing to any load connected to the terminal of the generator. In the generator, the magnetic fields of the rotor and stator rotate at the same speed. The angle between the rotor and stator is the torque angle. Torque is the rotational force applied to the rotor. The torque angle is the generator's rotor position with respect to the phasor. For a generator to provide power to the system which must be synchronized. Specific conditions must match between the generator and the system for synchronization to happen. The Generators, Torque Angle, and Synchronizing training course explores how generator components work together to create power. It discusses single- and three-phase systems. It discusses how torque angle impacts a generator's output. Finally, it explains the conditions necessary to synchronize a generator to the system. This course is part of the Electric Power Principles training series.
