<p><P>PROBLEM TO BE SOLVED: To solve the problem that the conventional reactive power compensator can not continue reactive power compensation without changing stepwise control width when some of capacitor banks out of a plurality of capacitor banks fail. <P>SOLUTION: The capacitor bank portion 30 constituted of capacitor banks 31 to 33 having capacitance in accordance with a sequence of the n-th power of 2 of basic capacitance includes a capacitor bank 31 of basic capacitance, a capacitor bank 32 constituted of sub-banks 40 and 41, and a capacitor bank 33 constituted of sub-banks 42 and 43. The capacitance of one sub-bank is set to a capacitance in accordance with a sequence of the m-th power of 2 of basic capacitance. When any one of the capacitor banks 31 to 33 fails, the capacitor banks following the failed capacitor bank substitute for a capacitor bank located immediately before itself. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
