tez y José Vallejos, es un estudio de
caso sobre los estudios de ampliación
de vida y modernización de la central
eléctrica Acaray, una de las centrales hidroeléctricas más grandes de
Paraguay. Los autores comienzan el
artículo con una introducción histórica de la generación hidroeléctrica

mitigación de los impactos ambientales
y sociales de los proyectos hidroeléctricos noruegos. Los autores concluyen
con una discusión sobre el desarrollo
continuo de la hidropotencia noruega.

en Paraguay y en Acaray. Luego, detallan un análisis comparativo de las
opciones de modernización para la
planta desarrolladas en colaboración
con la empresa de servicios públicos.
Se consideraron modelos de planificación de generación de energía y de
gestión de activos. Se recopilaron y
agregaron al modelo diversos datos
e información, incluidos datos hidrológicos, información sobre eficiencia
de las unidades, impacto ambiental
y proyecciones de carga. El modelo
permitió seleccionar una opción de
modernización ideal utilizando la optimización del gasto de capital basada
en el riesgo.
El último artículo sobre energía
hidroeléctrica es de Peter Donalek. El
artículo comienza con una historia de
la energía hidroeléctrica y el almacenamiento por bombeo en particular,
con un enfoque especial en la planta
Rocky River (terminada en 1928), la
primera de su tipo en los Estados Unidos. El autor detalla cómo las unidades
de almacenamiento hidroeléctrico se
pueden convertir en almacenamiento
por bombeo. Un motor/generador reversible y una bomba/turbina en un eje
común en la Unidad 2 de Hiwassee se
citan como ejemplo, junto con convertidores de frecuencia variable de estado
sólido. Se describen las sinergias entre
el almacenamiento por bombeo y la
generación nuclear, así como las tecnologías relacionadas con turbinas de
almacenamiento por bombeo eficientes
de velocidad ajustable. A continuación,
el autor analiza las experiencias de las
empresas japonesas de servicios públicos que utilizan máquinas de velocidad
ajustable para regular la frecuencia.
El artículo concluye con un análisis
de las unidades de almacenamiento
bombeadas por máquina de inducción
con doble alimentación, y una descripción general de las nuevas tecnologías
de almacenamiento por bombeo en
desarrollo.
La columna "En mi opinión", escrita
por Girish Behal, ofrece una visión de
cómo los desarrollos actuales en energía hidroeléctrica darán forma a su crecimiento futuro. Se describe el estado
