Abstract

Un sistema y método para la adquisición de vectores de corriente fuera del intervalo de rastreo de frecuencia para relés de protección de energía. Puesto que la frecuencia del sistema de energía varía a partir de la frecuencia de régimen, los vectores de corriente calculados de las muestras incluyen errores. Un intervalo de rastreo de frecuencia es utilizado para muestrear la forma de onda de señal en una relación que corresponde con la frecuencia cuando la frecuencia se encuentra dentro del intervalo de rastreo de frecuencia. Cuando la frecuencia se encuentra fuera del intervalo de rastreo de frecuencia, la forma de onda de señal es muestreada en una relación que corresponde con el máximo o mínimo del intervalo de rastreo de frecuencia en función de si la frecuencia excede o cae por debajo del intervalo de rastreo de frecuencia. La diferencia entre la frecuencia y el mínimo o máximo del intervalo de rastreo de frecuencia, es utilizada para corregir los vectores de corriente medidos de manera que se originen vectores de corriente precisos.
