APPARATUS AND METHOD TO REGULATE THE POWER FACTOR OF AN ELECTRICAL DISTRIBUTION LINE

摘要

accurate disclosurethe specification discloses an apparatus and amethod for regulating the power factor of the linepower distribution network; according to the method ofembodiments of the invention, the active power measurementthe line through a transducer whose output is adc voltage is proportional to the active power providedby the line; then, the reactive power of thethe line by a second transducer whose output isa voltage proportional to the power.provided by the reactive voltage; divideprovided by the transducer through the active powervoltage divider to obtain two reference voltages.l1 and l2, whose values are the limitsfor the power factor of the line. then, we compared thethe voltage provided by the power factor transducerwith the reference voltages to obtain l1 and l2two of the three logical levels of operations.a: we branch capacitor in casethe power factor is less than the line l1 and isan inductive, or plug in the case of capacitorsthe power factor is greater than the line l2, and isinductive, shall not engage in any transaction where thethe power factor is greater than the limit l1 or belowthe line l2, and is inductive.
