<P>PROBLEM TO BE SOLVED: To provide an instantaneous lowering compensation system that can compensate instantaneous lowering and exert a sufficient instantaneous lowering countermeasure function, even if the instantaneous lowering is repeated a number of times in a short time when the instantaneous lowering occurs at a commercial power supply side (power feeding system), while exerting a load equalization function by rated driving at a normal time, and is less in the restraint of an instantaneous lowering compensation time caused by an output. <P>SOLUTION: The instantaneous lowering compensation system 10 equipped with a multiple-lightning measure function is of a constant commercial power feeding type, and arranged at a customer system 1 that connects a commercial power supply 8 and a load 2 connected to the commercial power supply 8. The instantaneous lowering compensation system 10 comprises: a switch 41 that has a semiconductor as a constitution component, is inserted into the customer system 1 and connects or disconnects the commercial power supply 8 and the load 2; a power storable secondary battery 3 that serves both as a power feed source for the load equalization function and as a power feed source for the instantaneous lowering compensation function; an AC-DC converter 4 that is arranged between the secondary battery 3 and the customer system 1 and can perform charge and discharge; and a temperature monitor means 7 that purposes the effective utilization of an element constituting the AC-DC converter 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
