摘要： A magnet apparatus having two static magnetic field-generating sources constituted by current-carrying means (13 to 16) arranged concentrically to generate a uniform magnetic field directed in the first direction, each static magnetic field generating source having at least four current-carrying means. Assume that a predetermined line (18) lies in a first plane including a first axis extending in parallel with the first direction and passing through near the centers of the current-carrying means, a second axis intersecting the first axis perpendicularly and existing nearly at an equal distance from the second static magnetic field-generating source. When the geometrical center of the cross section of each current-carrying means is projected onto the predetermined straight line (18) on the first plane, the forward and reverse current-carrying directions of the corresponding current-carrying means are alternatingly arranged for each of the static magnetic field-generating sources.

摘要： A power generation system having a high following property to follow a load change is provided. A multi-shaft gas turbine power generation system includes a compressor 1 that compresses air to generate compressed air, a combustor 20 that generates a combustion gas from the compressed air and fuel, a gas generator 15 including a high pressure turbine 2a driven by the combustion gas, a power turbine 16 including a low pressure turbine 2b driven by a gas exhausted from the gas generator 15 and a main power generator 5 that generates power by a rotational force of the low pressure turbine 2b to supply power to the system, a sub-electric motor and power generator 6 connected to the gas generator 15 and the power turbine 16 via a frequency converter 10, and a control apparatus 200. The gas generator 15 and the power turbine 16 have different shafts. The control apparatus 200 receives a load target of the system and a load change factor of the system to output a control signal of the frequency converter.
