  "textContent": "A power factor control apparatus comprises a target power factor setting section (9a) which sets a target power factor range of the plurality of power generators (1a, 1b, 1c, 1d) in a fixed cycle, a comparing section (9a) which compares a voltage of a bus (10) with a predetermined voltage value range, a first control section (9a) which performs control, based on a result of the comparing section, to drop a voltage of at least one power generator (1a, 1b, 1c, 1d) whose power factor is the lowest, when the voltage of the bus (10) is higher than the predetermined voltage value range, and raise a voltage of at least one power generator (1a, 1b, 1c, 1d) whose power factor is the highest, when the voltage of the bus (10) is lower than the predetermined voltage value range, and a second control section (9a) which performs control of a voltage of a power generator (1a, 1b, 1c, 1d), whose power factor is out of the target power factor range, such that the power factor thereof falls within the target power factor range, when the voltage of the bus (10) falls within the predetermined voltage value range as a result of the comprising section (9a).",
