Desarrollo de un sistema automático de banco de capacitores para motores de inducción.

The technological proposal focuses on the development of a power factor correction module aimed at induction motors, blending theory with practice through specialized software tools. Following a thorough analysis of the theory and correction strategies for this type of motors, it was determined that the system's initial power factor was 0.30, while the ARCONEL regulation, resolution No. 074/17, sets an ideal value of 0.92. To comply with this regulation, capacitor banks were installed in parallel with the inductive load, with gradual adjustments in steps of 0.55, 0.65, 0.75, 0.90, and 0.95 of the power factor. The effectiveness of these improvements was verified using the Sentron Pac4200 device, which enabled the visualization of phasor diagrams at different power factors, demonstrating a progressive reduction in the phase angle between current and voltage with each adjustment made. Additionally, the proposal includes a graphical interface developed in LabVIEW for local control, supplemented with PLC logic in Tia Portal. This interface provides detailed information on electrical variables such as Power Factor, line-to-line voltages, phase currents, active power (kW), apparent power (VA), and reactive power (VAR), as well as graphical representations corresponding to line-to-line voltages, phase currents, and sinusoidal waveforms. By implementing the capacitor bank module, the following power factors were obtained: 0.55, 0.64, 0.78, 0.92, 0.99.
