Abstract

La presente tiene como objeto en un sistema de generación y almacenamiento de energía por bombeo de velocidad variable basado en el sistema de control de frecuencia primaria disminuir la variación de la velocidad de una turbina hidráulica que ocurre cuando se modifica un valor deseado de la energía activa, reducir el desgaste mecánico de la turbina hidráulica y alargar el ciclo de mantenimiento. Un aparato de control de operación para un generador/motor de velocidad variable en el cual una turbina hidráulica reversible está acoplada mecánicamente con el generador/motor y una bobina de estator del generador/motor está conectada con un red eléctrica a través de un conversor de frecuencia que incluye: un regulador de energía activa que controla el conversor de frecuencia de acuerdo con una señal de control de energía activa para llevar energía activa del generador/motor a su valor especificado y un regulador de velocidad de rotación que obtiene una señal de corrección de la producción de la turbina hidráulica reversible respecto del valor especificado de energía activa y un desnivel efectivo de la turbina hidráulica reversible y toma una señal suma de una señal de control de velocidad para llevar la velocidad de rotación de la turbina hidráulica reversible a su valor especificado y la señal de corrección de la producción de la turbina hidráulica reversible como una señal de control para la turbina hidráulica reversible.The purpose of this is in a system of generation and storage of energy by pumping of variable speed based on the primary frequency control system to decrease the variation of the speed of a hydraulic turbine that occurs when a desired value of the active energy is modified , reduce the mechanical wear of the hydraulic turbine and extend the maintenance cycle. An operation control apparatus for a variable speed generator / motor in which a reversible hydraulic turbine is mechanically coupled with the generator / motor and a generator / motor stator coil is connected to an electrical network through a power converter. frequency including: an active energy regulator that controls the frequency converter in accordance with an active energy control signal to bring active energy from the generator / motor to its specified value and a rotation speed regulator that obtains a correction signal of the production of the reversible hydraulic turbine with respect to the specified value of active energy and an effective slope of the reversible hydraulic turbine and takes a sum signal of a speed control signal to bring the rotation speed of the reversible hydraulic turbine to its value specified and the correction signal of the reversib hydraulic turbine production I read it as a control signal for the reversible hydraulic turbine.
