Abstract

Sistema y método de control de la rampa de potencia para grupos hidráulicos.#Cuando se aumenta la potencia de una turbina hidráulica aparece una onda de presión negativa que se desplaza desde la turbina hasta el embalse superior. El valor de esta onda es tanto mayor cuanto mayor es la rampa de potencia. La cavitación se puede alcanzar si debido a esta onda de presión en algún punto de la tubería se alcanzaran presiones demasiado bajas, tales que el agua cambiara a estado gaseoso, produciéndose daños graves en la tubería o en la turbina.#La presente invención tiene por objeto el ajustar la rampa de potencia en grupos hidráulicos en función de la altura del embalse superior, de forma que se obtenga la mejor respuesta del grupo en cada situación sin tener problemas de cavitación en el sistema hidráulico.System and method of control of the power ramp for hydraulic groups. # When the power of a hydraulic turbine is increased, a negative pressure wave appears that travels from the turbine to the upper reservoir. The value of this wave is all the greater the greater the power ramp. Cavitation can be achieved if, due to this pressure wave at some point in the pipeline, too low pressures are reached, such that the water changes to a gaseous state, causing serious damage to the pipe or the turbine. # The present invention is intended object to adjust the power ramp in hydraulic groups according to the height of the upper reservoir, so that the best response of the group in each situation is obtained without having cavitation problems in the hydraulic system.
