The modernization of PH Rio Macho allowed greater efficiency and reliability in operation to the units. To prolong the life of the asset is intended that the generators deliver the highest possible efficiency. Through the IEEE 112-E efficiency and points most suitable operation is estimated, which estimates efficiency similar to IEC 60032-2, for checking superimpose Both graphs from data in the PH Rio Macho a set of graphs were generated in order to assess and monitor the chronological behavior of the unit. The function of the graphic is to create a basis for monitoring, which allows you to have a starting point in assessing the state of the asset. Certain variations present in efficiency possible failures demonstrate that the generator presents in its operation, as the partial discharge capacity weaken mica insulation. An analytical curve that allowed the theoretical calculation gain strength in their results, because the comparison contrasts both methods in order to corroborate the value obtained in the field was developed. variations that season introduces the flow of the river were evaluated, showing that to the rainy season efficiencies generators are greater for longer times, affecting less than generators because the changes in the powers are few. Other studies conducted were curves Capability to define the operating values Rio Macho, as well as the overall efficiency that presents both the transformer and generator at rated power, and the effects that can lead to lead to generators operating in condenser mode.
