Abstract

The aim of this project is to build a system for the measurement of electrical energy consumption which is very accurate, reliable and operationally versatile, allowing for the remote programming and acquisition of data.At present, consumption figures are collected manually, generally once a month. This procedure is of low reliability and does not allow for the adoption of a considerable social gain, which would be the establishment of lower tariffs at specific times of the day, that’s to say, the charging of differentiated, more socially fair tariffs. The proposed system consists of a remote module next to the electronic meter which, via communications carrier, transports the data to the concentrator terminal on the post which possesses the transformer for the area covered. From this point, via transmission through cell phone, the company’s center of operations collects the data for processing.With the use of sensors on the meters, the remote module continually monitors pulses relating to the consumption of energy. This information is stored in memory units contained within the modules. The module can be accessed at any time via cell phone and the data stored in the memory units interrogated by specific man-machine commands. The centralized computer can even be timetabled to carry out an automatic sweep of all the remote modules of a given urban area and at a preprogrammed date and time. Differential tariffs based on time of day and day of the week and the month can be applied by specific programming, recorded in existing e2prom memory in the remote modules. (AU)
