Tag hinzufügen | Zusammenfassung: | The Hydroelectric Power Plant called "Illuchi 1" of Empresa Eléctrica Provincial Cotopaxi S.A (ELEPCO SA), is made up of four turbines that drive 4 sets of generators, of which No. 1 and 2 have the capacity to generate 872 kVA, being its actual exploited power of 600 kW; Meanwhile groups No. 3 and 4 have a range of 1750 kVA, producing only 900kW and 1400kW respectively, showing that there is a low production of group 3 of the plant. Therefore, the purpose of this research focused on evaluating the efficiency of energy production in the group 3 generator. The methodology established for this purpose was through a quantitative approach, based on collecting and analyzing numerical data, on electrical and mechanical variables that directly and indirectly affect electricity generation; In addition, documentary and field research was applied, both in original documents, photographs, technical maintenance reports and historical data on the operation of the units and the measurement of the variables directly to the object of study; and taken from texts and articles that directed the evaluation and proposal of the generating group. To determine the current conditions of the insulation system between the winding and the ground walls, high potential electrical tests (HIPOT) were carried out according to IEEE 95-2002, and impulse comparison (SURGE) according to IEEE 522-2004, yielding results that indicate the contamination and poor state of the insulation, for which maintenance was carried out on generation group No. 3. After the intervention, it was possible to increase the efficiency of the machine by 1.12%, which is why the energy production capacity was improved, reaching a power of 1400 kW. |
