Corrección de factor de potencia en una industria de balanceado de camarón de la provincia del Guayas.

Abstract

This study develops a power-factor correction proposal for an anonymized shrimp-feed manufacturing plant in Guayas Province. Because a complete measurement campaign was unavailable, an engineering case was built using clearly identified assumed values: a 5/6.25 MVA substation, 2.50 MVA maximum apparent demand, 480 V secondary voltage, and a representative 0.90 power factor, including drops below the 0.94 tariff threshold. Power-triangle equations yielded a required compensation of 632.8 kVAr to reach 0.98; therefore, a 650 kVAr eight-step automatic detuned bank was selected. Estimated main current decreases from 3,007 A to 2,761 A and about 204 kVA of capacity is released. The referential economic evaluation uses a USD 55,000 investment and an estimated 0.75-year payback. These are academic design results and must be validated through field measurements before implementation.
