Abstract

La invención describe un método de implementación de control de frecuencia del lado inversor para transmisión de corriente continua de alto voltaje/ultra-alto voltaje, que comprende las siguientes etapas: transmitir una desviación entre la frecuencia de red eléctrica del lado inversor y frecuencia nominal al controlador de frecuencia del lado inversor, en donde el controlador de frecuencia regula y emite una cantidad de modulación al adoptar parámetros auto-adaptivos de acuerdo con diferentes condiciones de operación; cuando la comunicación entre estaciones es normal, la salida de cantidad de modulación del controlador de frecuencia del lado inversor causa que el lado rectificador y el lado inversor forme un nuevo orden de energía/corriente a través de la comunicación entre estaciones, logrando de esta manera el control de frecuencia del lado inversor al cambiar el tamaño de la energía de transmisión; cuando la comunicación entre estaciones es anormal, convertir el lado inversor a control de corriente a partir de control de voltaje y convertir el lado rectificador a control de voltaje a partir de control de corriente; superponer la salida de cantidad de modulación del controlador de frecuencia del lado inversor al orden de energía/corriente del lado inversor; cambiar el tamaño de la energía de transmisión para lograr el control de frecuencia del lado inversor. El método logra la función de regulación eficiente y rápida en la frecuencia del lado inversor, y resuelve de manera efectiva el problema del control de frecuencia del lado inversor para la falla de comunicación entre estaciones.
