<p><P>PROBLEM TO BE SOLVED: To provide a reactive power compensator that effectively shares output with respect to a plurality of compensators, or an output sharing method for the same. <P>SOLUTION: The reactive power compensator is connected to a power system. The reactive power compensator has a plurality of compensators respectively which stabilize a voltage or a current of the power system on the basis of a voltage output by the reactive power compensator or a current flowing in the power system, a priority-order determining part 1 for determining the output priority order n which is assigned to share a compensation capacity of the reactive power compensator for each of the plurality of compensators, and a sharing-amount arithmetic assignment part 2 which shares the output of the reactive power compensator by the computation formula Sn+1=Sn-Vn (n=1, 2, 3, 4 ...) (1) (however, Sn+1 is a remaining capacity of the reactive power compensator, Sn is a current capacity of the reactive power compensator, and Vn is output power of an n-th compensator in the plurality of prioritized compensators) on the basis of the priority order determined by the priority-order determining part and sets Vn=Sn if it is Sn+1<0. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
