Abstract
A computer system at a substation of an electrical grid examines on-grid communication channels and for very channel, the system compares and correlates a GLA signal provided by a downstream transmitter on that channel to a reference GLA signal. The channel that provided the signal with the best correlation is mostly likely the channel with the transmitter. Thus, the feeder and phase of the signal can be determined from the correlation of signals.
Claims14
A method for determining a phase line on which a transmitter is transmitting, comprising:
- receiving, by a receiver, on a first power distribution phase line of a plurality of power distribution phase lines, a first copy of a signal transmitted by one transmitter of a plurality of transmitters;
- digitizing the first copy of the signal;
- receiving, by the receiver, on a second power distribution phase line of the plurality of power distribution phase lines, a second copy of the signal transmitted by the one transmitter;
- digitizing the second copy of the signal;
- correlating, by a processing device, the first copy of the signal received on the first power distribution phase line and the second copy of the signal received on the second power distribution phase line with a reference signal;
- and
- determining that the one transmitter transmitted the signal on the first power distribution phase line and not on the second power distribution phase line.
A receiver for determining a phase line on which a transmitter is transmitting, comprising:
- a memory;
- and
- a processor device coupled to the memory and configured to:
- receive on a first power distribution phase line of a plurality of power distribution phase lines, a first copy of a signal transmitted by one transmitter of a plurality of transmitters;
- digitize the first copy of the signal;
- receive on a second power distribution phase line of the plurality of power distribution phase lines, a second copy of the signal transmitted by the one transmitter;
- digitize the second copy of the signal;
- correlate the first copy of the signal received on the first power distribution phase line and the second copy of the signal received on the second power distribution phase line with a reference signal;
- and
- determine that the one transmitter transmitted the signal on the first power distribution phase line and not on the second power distribution phase line.
