Spiral Vector Theory of Salient-Pole Synchronous Machine

Almost all electric energy of electric industries is generated by synchronous generators, which are either salient-pole synchronous generators or have saliency to some extent. As the rotor rotates, inductances of the three phase winding vary due to the saliency and it makes analysis of generator performance difficult. Even adequate computer simulations have not been provided by the conventional theories, such as the d, q axis theory. In this paper the spiral vector method will be applied to analyses of the salient-pole synchronous generator, and adequate analytical solutions and computer simultations will be derived.
