<P>PROBLEM TO BE SOLVED: To provide a synchronous generator that can simultaneously conduct outputs of a single-phase three-wire power and a three-phase three-wire power can prevent occurrence of unbalanced voltage in two sets of star-type three-phase windings while increasing the capacity of the three-phase three-wire power. <P>SOLUTION: In the synchronous generator, a single-phase three-wire power (N, U, V) is formed by a terminal being formed by connecting two different-phase terminals (V, U') in two sets of a first star-shape three-phase winding and a second star-shape three-phase winding, another phase terminal (U) in the first star-shape three-phase winding and another phase terminal (V') in the second star-shape three-phase winding. A first winding in a primary side, connected to a neutral point (O) and the three phase terminals (U, V, W) respectively of the first star-shape three-phase winding and a second winding in the primary side, connected to a neutral point (O') and the three phase terminals (U', V', W') respectively of the second star-shape three-phase winding are respectively arranged in the same phase in the primary side of three sets of single-phase transformers. A three-phase three-wire power (R, S, T) is formed in a secondary side of the three sets of single-phase transformers connected in the star-shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
