| Abstract |
The motivation for this work was the possibility of
utilizing the motor feeder cable as a communication channel in
the inverter driven electrical drives. The simulation of the data
transmission and electromagnetic interference in the motor cable
claims a model. The newest power line transmission methods
utilize the frequency band up to 30 MHz. In this article,
modelling RF (Radio Frequency) signal propagation in the motor
feeder cable is discussed. The RF signal propagation is modelled
in the inverter driven electrical drives. The simulation is
concerned the frequency band 100 kHz – 30 MHz. The effect of
each component is taken into account with a model or a
measurement. The simulation model takes into consideration the
frequency depending damping of the channel and the effect of the
coupling interfaces and impedance mismatching. The laboratory
experiments are carried out for proving the applicability of the
proposed method. The channel model is a tool in developing the
coupling interfaces to the power line modems. It also helps to
estimate the data transfer rates and limitation in the motor cable. |
