Abstract

Sistema de aprovechamiento de la energía almacenada en la inercia mecánica del rotor de una turbina eólica. Permite utilizar la energía mecánica almacenada en un elemento rotativo para contribuir a la estabilidad dinámica y al control de la frecuencia de la red a la que se encuentra acoplado dicho elemento rotativo. El principal campo de aplicación de esta invención es el de los aerogeneradores donde puede ser aprovechada la energía inercial almacenada en el rotor de dichos aerogeneradores. En el mismo participan dos convertidores de potencia espalda contra espalda, un rectificador (4) y un inversor (6) con un sistema de control (16) que genera el par de referencia Topt que garantiza una óptima captura de energía para cualquier velocidad de viento. El sistema añade dos componentes de par: la primera DTf a la salida del bloque de control (20) con el fin de garantizar que la frecuencia de la red de distribución siga a una de referencia. La segunda componente de par generado por el bloque de control (18) realiza el cálculo del incremento de par DTi, cuya finalidad es la de contribuir a la mejora de la estabilidad dinámica de la red de distribución aportando al sistema un par inercial similar a la potencia inercial equivalente de un generador síncrono conectado a la red de distribución de una central de generación convencional. Como resultado se obtiene el par de referencia Tref que es la consigna de par que deberá seguir el circuito rectificador (4) para que el par eléctrico del generador (3) siga a dicha referencia y se cumplan los objetivos de control.System for harnessing the energy stored in the mechanical inertia of the rotor of a wind turbine. It makes it possible to use the mechanical energy stored in a rotating element to contribute to the dynamic stability and to control the frequency of the network to which said rotating element is attached. The main field of application of this invention is that of wind turbines where the inertial energy stored in the rotor of said wind turbines can be used. Two back-to-back power converters participate in it, a rectifier (4) and an inverter (6) with a control system (16) that generates the Topt reference torque that guarantees optimal energy capture for any wind speed. . The system adds two torque components: the first DTf at the output of the control block (20) in order to guarantee that the frequency of the distribution network follows a reference one. The second component of torque generated by the control block (18) performs the calculation of the torque increase DTi, the purpose of which is to contribute to the improvement of the dynamic stability of the distribution network by providing the system with an inertial torque similar to that of Equivalent inertial power of a synchronous generator connected to the distribution network of a conventional generation plant. As a result, the reference torque Tref is obtained, which is the torque command that the rectifier circuit (4) must follow so that the electrical torque of the generator (3) follows said reference and the control objectives are met.
