摘要： PROBLEM TO BE SOLVED: To provide a field winding of a high temperature superconducting generator which is hardly affected by field component of the (c) axial direction, and can do without decreasing mean current density when critical current density is part decreased by field components in the (c) axial direction. SOLUTION: Pancake type coils 3, on which high temperature superconductive tapes 2 are flatly wound are laminated in the radial direction, and a field winding is constituted. Tapes 14, 13 whose critical current densities to a magnetic field in the (a) (b) axes directions or the (c)-axis direction are large are arranged so as to be suitable for a magnetic field condition. In the part where critical current density is small, a number of the high temperature superconductive tapes 2 which are aligned in parallel is increased, or the sectional area is enlarged, thereby preventing partial decrease of critical current density which is to be caused by a magnetic field in the (c) axis direction. Nevertheless when a part in which critical current density is remarkably decreased exists, the high temperature superconductive tape 2 is not wound around the part, and electrical conduction to good conductor is constituted.

摘要： PURPOSE: To reduce the higher harmonic generating amount of an LCI power generation system by pairing a plurality of synchronous generators and shifting the phase of the primary or secondary winding of the input transformers of LCIs in accordance with the number of converting phases of the LCIs, and then, starting this pair of synchronous generators at the same timing. CONSTITUTION: A power generation system is constituted of (n) pairs of units 1,..., (n) each of which is composed of two synchronous generators and the generators constituting the unit 1 are started in paired states. When, for example, the system is started in the numerical order of the units, the synchronous generators 1-1A and 1-1B of the unit 1 are simultaneously started by means of LCIs 2-1A and 2-1B and, thereafter, the succeeding units are successively started by means of LCIs 2 in numerical order, with the two generators constituting each unit being started simultaneously. In this case, the phase of the primary or secondary winding of the paired transformers 4 on the input side of each unit 1,..., (n) is shifted so that higher harmonics can be offset by each other in corresponding to the number of converting phases of the LCIs 2.

摘要： PURPOSE:To reduce the occupying area of a device, to simplify operation at the time of stoppage and to improve profitability by turning a prime mover and a superconducting generator by the driving force of rotational speed, where thermal stress by the uneven distribution of a refrigerant in the vessel of a rotor is not generated. CONSTITUTION:When the usage of a steam turbine is assumed as a prime mover, there is the number of revolution NMAX as an upper limit for cooling blades used when cooled steam is not ventilated. On the other hand, there is the minimum number of revolution NMIN (rmp) only for rotating liquid helium 2-3 on the inwall of a vessel 2-1 in succession in a superconducting generator 2. Consequently, NMAX>=Nopt>=NMIN is set from said NMAX and NMIN while using the optimum number of revolution of each shaft 1a, 1b of the prime mover 1 and the superconducting generator 2 as Nopt. Accordingly, even when the superconducting generating set is stopped, the generation of thermal stress by the uneven distribution of liquid helium 2-3 in the vessel 2-1 of a rotor is prevented.

摘要： PURPOSE: To reduce duty of units other than a load-commutated inverter, by connecting a transformer to an output terminal of the inverter and a transformer to an output terminal of a synchronous generator. CONSTITUTION: When a synchronous generator is driven, a breaker 2a is opened to operate a converter 2c and a DC current (Id) is carried through a DC reactor 2d and an inverter 2e. In the inverter 2e, the DC current (Id) is changed into an AC current (Iac) with a variable frequency on using a control command from a phase control unit 2g. The synchronous generator is driven by the AC current (Iac) through a transformer 2f. When reactive power is lacking as the load increases abruptly in power system, the load-commutated inverter 2 is connected to an output terminal of the synchronous generator even after the synchronous generator is driven. Then, the reactive power is fed as an output from the inverter 2e in the load-commutated inverter 2.

摘要： PURPOSE:To improve the adsorbing and discharging capacity of a hydrogen storage alloy and set the pressure of gas in a rotary machine quickly at a predetermined pressure by attaching a fan to the receiving case of the hydrogen storage alloy, in the hydrogen-cooled rotary electric machine. CONSTITUTION:A case 4, provided at the outside of a rotary electric machine, is filled with powdered hydrogen storage alloy and is provided with a heater 3 and a cooler 2 for heating and/or cooling the hydrogen storage alloy.

According to this constitution, the powdered hydrogen storage alloy is mixed by the fan 7 whereby the hydrogen gas adsorbing and discharging capacity of the hydrogen storage alloy is unified and the pressure of the hydrogen gas in the rotary electric machine 1 may be controlled efficiently. On the other hand, the fan 7 is controlled at the optimum rotating number by the rotating number controller through a load fluctuating rate and, therefore, contact between the hydrogen storage alloy and the hydrogen gas may be activated to set the pressure of the hydrogen gas in the machine quickly at the optimum value and permit the highly efficient operation of the hydrogen-cooled rotary electric machine.
