In multigroup hydroelectric plant operating at partial loads, the maximum each group efficiency and the random combination of these, differ from the design efficiency of the plant at full load. These plants are conditioned to operate at partial loads, both in times of drought and periods of oversupply national electric grid. The period of drought in Peru is nine months per year, a situation that involves economic losses due to inadequate flow regulation and group choice efficiencies conditions below their optimum values. The aim of this work is the development optimizing efficiency process of a multigroup hydroelectric power plant, for any level of power generated in the daily interconnected generation program. The results are maximizing turbine efficiency and combined-group for each power output of the plant, outside its nominal conditions, also a computer program is constructed in Matl...

En una Central Hidroeléctrica multigrupo que opera a cargas parciales, la máxima eficiencia de cada grupo y el de la combinación aleatorias de estos, difieren de la eficiencia de diseño de la central a plena carga. Estas centrales están condicionadas a operar a cargas parciales, tanto en épocas de estiaje como en tramos de sobreoferta eléctrica del sistema interconectado nacional. El periodo de estiaje en Perú alcanza a nueve meses del año, situación que implica pérdidas económicas debido a la inadecuada regulación del caudal y elección de grupo, a condiciones de eficiencias por debajo de sus valores óptimos. El objetivo de este trabajo es el desarrollo de un proceso de optimización de la eficiencia de una Central Hidroeléctrica multigrupo, para cualquier nivel de potencia a generar en el programa diario de generación interconectada. Como resultados se obtiene la maximi...
