Abstract
Contador estático de energía eléctrica basado en el procesamiento de señales aleatorias. La invención se refiere a un contador estático de energía eléctrica, constituido por los bloques (1, 7) conectados a los cables de la red eléctrica que generan las medidas U{sub,I e I{sub,I proporcionales a la tensión (U) y a la corriente (I); los bloques (2, 9) que rectifican ambas magnitudes para obtener las señales [U] e [I]; los bloques (3, 10) que generan una señal que indican el signo de U e I respectivamente; los bloques (4, 11) que convierten a codificación digital las señales medidas y rectificadas; el bloque (5), incorporado de forma novedosa, que genera pares de números aleatorios de 10 bits que son empleados en las comparaciones digitales realizadas por los bloques (6, 12) para obtener una codificación mediante trenes de pulsos aleatorios U{sub,e e I{sub,e , de las señales [U] e [I]; y el bloque (13) que genera el tren de pulsos aleatorios P{sub,e que codifica la potencia. En el contador (14) se integra la potencia consumida, atendiendo a los signos de U e I, obtenidos a partir de (15).Static electric energy meter based on random signal processing. The invention refers to a static electric energy meter, consisting of the blocks (1, 7) connected to the cables of the electrical network that generate the measurements U {sub, I and I {sub, I proportional to the voltage (U ) and current (I); the blocks (2, 9) that rectify both quantities to obtain the signals [U] and [I]; the blocks (3, 10) that generate a signal indicating the sign of U and I respectively; the blocks (4, 11) that convert the measured and rectified signals to digital encoding; the block (5), incorporated in a novel way, that generates pairs of 10-bit random numbers that are used in the digital comparisons made by the blocks (6, 12) to obtain an encoding by means of random pulse trains U {sub, ee I {sub, e, of the signals [U] and [I]; and the block (13) that generates the random pulse train P {sub, e that encodes the power. The consumed power is integrated in the meter (14), attending to the signs of U and I, obtained from (15).
