Evaluación técnica de los sistemas eléctricos y propuesta de correctivos para la empresa Sigmaplast

Abstract

The present degree work shows the analysis of energy quality, service and energy efficiency of the different electrical variables of the Sigmaplast company. whose main activity is the production of flexible food packaging. In accordance with the regulations in force in Ecuador, the Electricity Regulation and Control Agency (ARCONEL) has established parameters and measurements in order to verify the quality of energy and service for consumers, within the international standards that appear in regulation (ARCONEL 005/18) we have the International Electrotechnical Commission (IEC 60868- IEC 61000-4-7, IEC 61000-4-30); the Institute of Electrical and Electronic Engineering (IEEE Std 519-2014) and the American National Standards Institute (ANSI C84.1-2016). The measurement of the electrical parameters was carried out at the common coupling point (PCC) at the outlet of the transformation chamber in the primary distribution board A and in the primary distribution board B, the equipment occupied is a brand energy analyzer Fluke 435- II, the analysis period ranged from December 18, 2019 to January 2, 2020 with a duration of 7 consecutive days for each of the boards. The grounding system measurement was performed, as well as a thermographic measurement of the main and secondary boards. For this analysis, the single-line diagram was drawn up in AUTOCAD, power flow in DIgSILENT and reference plans of the lighting system, power system and grounding system. To finalize this work, a proposal for corrective actions to be implemented will be made, including improving the power factor through the acquisition of a capacitor bank, protection against transient overvoltages, load unbalance, enabling the generator units and electrical maintenance.
