A PLC BASED ENERGY CONSUMPTION MANAGEMENT SYSTEM PRELIMINARY FIELD TESTS AND SIMULATION RESULTS

摘要

In power line communications the signal transmission characteristics of the power line carrier are very significant. In this paper some preliminary field test results, concerning signal transmission characteristics on power cables in an existing street lighting, installation are reported. The influence of electrical loads in signal transmission over power lines is also commented. Simulation results obtained by EMTP for the above installation are compared to the actual measurements, showing satisfactory agreement.
