Abstract

Un método para compensación de caída de voltaje del inversor, el método caracterizado por: realizar una prueba momentánea de caída de voltaje para capturar una característica de carga de una carga instalada en un sitio de campo con un punto de ajuste básico para hacer frente a una caída (S1) de voltaje momentáneo; determinar si una carga relevante es una carga que requiere un control de corriente adicional en respuesta a la característica (S2) de carga captada; ajustar la carga relevante como sujeto de control de corriente cuando se determina que la carga relevante es el sujeto de control de corriente como resultado de la determinación (S3), y establecer la carga relevante como un sujeto de control de corriente cuando se determina que la carga relevante no es el sujeto de control de corriente como resultado de la determinación (S4); ajustar para realizar una compensación momentánea de la caída de voltaje utilizando control de voltaje y corriente en un inversor relevante cuando se produce una falla momentánea de energía a una carga que se configura como el sujeto de control de corriente durante el funcionamiento (S5, S6) del inversor; reducir una frecuencia de salida de un inversor para obtener una energía regenerativa cuando se determina que ha ocurrido una falla de energía durante la operación (S11, S12) del inversor; ajustar el aumento/disminución de la frecuencia de salida del inversor en respuesta al tamaño de la corriente y voltaje excedente en función de una corriente de salida y el voltaje del enlace de CC del inversor (S14, S15, S16, S17); aumentar un voltaje de salida del inversor para evitar un flujo de corriente excesivo cuando se produce una restauración de energía en un estado (S21) de falla de energía; y volver a una velocidad anterior a la caída momentánea de voltaje aumentando gradualmente la frecuencia de salida del inversor en un estado donde la corriente de salida del inversor no supera un límite de sobreintensidad monitorizando la corriente de salida del inversor (S24, S25, S26, S27).
