Concurrent phase communication in TWACS

摘要

A method for concurrently communicating over each phase of an electrical power distribution network (N). A first outbound signal (SO 1 ) is transmitted over one phase (AN-A) of a bus (S) by an outbound modulation unit. The unit is released as soon as the first outbound signal (SO 1 ) is transmitted so the unit can transmit a second outbound signal (SO 2 ) over a second phase (BN-B or CN-C) of the bus. The second outbound signal is transmitted concurrently with an inbound signal (IB 1 ) sent in response to the first outbound signal (SO 1 ). The unit is again released, as soon as the second outbound signal (SO 2 ) is transmitted, so the unit can transmit a third outbound signal (SO 3 ) over the third phase (BN-B or CN-C) of the bus. This third outbound signal is transmitted concurrently with a second inbound signal (IB 2 ) sent in response to the second outbound signal (SO 2 ). The method allows concurrent communications over all three phases of the network (N).
