Abstract:
This paper reports a power quality monitoring instrument to be integrated in the electric energy distribution network of CELPA, the electric utility of Belem – Para – Brazil. The instrument, based on a 68HC11 microcontroller collects data at custumer service entrance locations on the feeder, recording both triggered and sampled data voltage signal, wich are processed by a Real Time Executive that manages several tasks, enabling the calculation of ANEEL (Brasilian Electricity Regulatory Agency) continuity and conformity indicators. The utility has evaluated the monitoring instrument in a pilot project with good results, assuring low cost, high performance, reliability and capability of integration with the Energy Distribution Control Center.
