AnSem and Rational Products developed a remote energy management demonstrator.
Within 5 to 10 years, about 100 million smart meters and appliances will be installed worldwide. This requires monitoring and controlling devices at low costs and low power consumption. Current Power Line Communication (PLC) technologies are either too costly (developed for multimedia applications) or have a too low data rate for an effective monitoring (e.g. building automation).
AnSem and Rational Products bv brought their knowledge and expertise together in the frame of the Crossroad Program to develop a remote energy management demonstrator.
The functional prototype exists of several nodes distributed over a building and a central energy gateway. The nodes measure the energy consumption of appliances and regulate the electricity flow. Each node is connected to a master controller/gateway through the power line and communicates over the G3-protocol.
For this prototype, AnSem connected its PLC-Analog Front End chip with a commercial digital modem and Rational Products power line network technology. The set up communicates over the Power Line in different frequency bands (between 10 and 500 kHz) with the use of programmable filters on the AFE-chip. The high signal sensitivity of the receiver assures robust communication over noisy power lines in buildings. The system has been successfully demonstrated in the offices of AnSem showing that attenuations of more than 86 dB between transmitter and receiver do not affect the communication quality. This is higher than the performance of other comparable chips under similar conditions.
