<p>PROBLEM TO BE SOLVED: To improve a power factor at a power-receiving point while minimizing a total loss in a plurality of power generators installed in the premises of a customer.SOLUTION: A automatic power factor control system comprises: a reactive power detector 4 for detecting reactive power at a power-receiving point 2; active power detectors 5-5for detecting active power generated by power generators 3-3; a power factor arithmetic unit 6 for calculating, on the basis of the reactive power at the power-receiving point 2 and the active power generated by the power generators 3-3, an optimum value of the reactive power of the power generators 3-3for minimizing a sum total of loss costs of the power generators 3-3; and automatic power factor regulators 7-7for controlling, on the basis of the reactive power to be generated by the power generators 3-3as calculated by the power factor arithmetic unit 6, the field current of each of the power generators.</p> |
