PROBLEM TO BE SOLVED: To reduce the size and weight of the equipment as a whole and further save energy. SOLUTION: Rectifiers 26A, 26B, 27 are installed on the output side of AC generators 1A, 1B and an emergency AC generator 2, and a bus is constituted as a DC bus 28. A large apparatus such as an active filter which has been necessary for eliminating higher harmonics which are generated on a bus can be omitted. Since the bus is the DC bus 28, a battery can be connected. Thereby it is made unnecessary to always operate the emergency AC generator 2 on standby, so that energy can be saved. |
