Abstract

PURPOSE:To obtain a super quick-response excitation device with compact, a lower loss and high quick-response efficiency by storing energy for super quick-response excitation at a lower loss in the case of normal operation and supplying energy for super quick-response excitation to a field magnetic circuit in case of necessity. CONSTITUTION:In the case of normal operation, the excitation energy is supplied to a motor field magnetic winding 1 from a main excitation device 2. At this time, in an excitation device 8 for super quick-response excitation, the excitation energy is stored into a superconductive circuit consisting of a superconductive coil 7 and a superconductive switch 5. At the time of super quick-response excitation, a closing switch 3 is turned to ON position as well as turning of the superconductive switch 5 to OFF position, and the excitation energy is supplied to the motor field magnetic winding 1 by connecting the excitation device 8 for super quick-response excitation to the motor field magnetic winding 1. According to the constitution, the loss from the whole excitation device is reduced, and, at the same time, the quick-response efficiency is improved.
