摘要：A power factor control apparatus comprises a target power factor settingsection which sets a target power factor range of the plurality of power generators in afixed cycle, a comparing section which compares a voltage of a bus with a predetermined

voltage value range, a first control section which performs control, based on a result ofthe comparing section, to drop a voltage of at least one power generator whose powerfactor is the lowest, and raise a voltage of at least one power generator whose powerfactor is the highest, and a second control section which performs control of a voltage ofa power generator, whose power factor is out of the target power factor range, such thatthe power factor thereof falls within the target power factor range.
