摘要：<P>PROBLEM TO BE SOLVED: To contemplate the increase of the efficiency of a cogeneration system by optimizing the calorific power of a heater for recovering a dump power in a way to double the magnitude of a dump power and reduce the generation of noise. <P>SOLUTION: In the cogeneration system 1 provided with a private power generation means 11; and a dump power recovering part 6 to recover the dump power of the private power generating means 11 in form of heat and supply the power of the private generating means 11 to a private load 4 with the power of the private generating means 11 synchronized with a commercial power source 5 of an electric power company, the dump power recovering part 6 is provided with a plurality of heaters 61-66 connected between the U-phase and the N-phase of the generating means 11; change-over switches 621-661 individually turning on and off each of a plurality of the heaters 61-66; and a phase control device 611 to effect control of a phase in regard to a current carried to the heater 61, having a lowest rated calorific power, of a plurality of the heaters. <P>COPYRIGHT: (C)2006,JPO&NCIPI
