Abstract

Un combinador que calcula energía producida por cada alimentación de panel durante el día, y calcula un valor de resistencia necesario para calcular la energía al inyectar una corriente conocida en cada alimentación de panel en la noche y medir el voltaje resultante a través de un elemento resistivo en cada alimentación de panel. Una derivación de voltaje a través del dispositivo de protección en cada alimentación de panel permite que la circulación de panel permite que la circulación de control de circuito lógico mida el voltaje a través de cada dispositivo de protección. En la noche, se inyecta una corriente conocida en cada alimentación de panel y el voltaje a través de cada dispositivo de protección se mide. Enchufando la corriente y el voltaje en la Ley de Ohm, se calcula una resistencia de cada dispositivo de protección, entonces ese valor de resistencia se usa durante el día para calcular energía producida por cada cadena en tiempo real y para monitorizar el desempeño de cada cadena. Cuando el desempeño de la cadena individual disminuye, se indica una alarma para ayudar al operador a resolver el problema de que panel individual dentro de la cadena es responsable del desempeño pobre de la cadena.
