ABSTRACT:
A superconduction power storage apparatus includes a superconduction coil for storage and release of electrical energy, and a separately excited thyristor conversion unit having d.c. terminals connected to the said superconduction coil and a.c. terminals connected to an a.c. power source. The conversion unit is arranged so as to convert the electrical energy from a d.c. form to an a.c. form and vice versa between the superconduction coil and the a.c. power source. An on-load voltage regulator is connected between the a.c. side terminals of the thyristor conversion unit and the a.c. power source, and is arranged for adjusting the voltage appearing at the a.c. terminals of the thyristor conversion unit.
