Method for automatic mapping of AC phase conductors and identification of AC buses in a multi-bus power system

A system for detecting if a remote power providing device is associated with a power supply, wherein the remote power providing device is upstream of the power supply, the system comprising:

• a controller having machine readable, non-transitory executable code running thereon for varying an input characteristic of the power supply;
• the controller further being configured to:
• perform an analysis of a measurement obtained from a measurement subsystem relating to a measured characteristic of power being provided from the remote power providing device, while the controller is varying the input characteristic of the power supply;
• and
• based on the analysis, determining whether the remote power providing device is electrically associated with the power supply;
• and
• wherein the varying of the input characteristic of the power supply includes generating a signal instructing the power supply to vary its input power factor, and the measured characteristic of power is a change in a power factor of the power being provided from the remote power providing device to the power supply.

A system for detecting and mapping which ones of a plurality of electrically powered devices are being powered by a power supply, the system comprising:

• a controller having machine readable, non-transitory executable code running thereon for varying a characteristic of a power output signal being supplied by the power supply, by a predetermined amount, to produce a modified input signal for application to one or more electrically powered devices downstream of the power supply;
• and
• the controller further being configured to:
• compare electrical signal measurements obtained by, and received from, a measurement subsystem, each said electrical signal measurement relating to a measured input signal present at an input of each of the plurality of electrically powered devices;
• and
• based on comparisons between the measured input signals and the modified input signal, to detect which ones of the plurality of electrically powered devices are being powered by the given power supply.

A method for detecting if a remote device is associated with a power supply, the method comprising:

• using a controller having machine readable, non-transitory executable code running thereon to vary a characteristic of a signal being applied to the power supply;
• using the controller to:
• receive and compare an electrical signal measurement obtained from a measurement subsystem relating to a measured input signal associated with the remote device;
• and
• determine, based on a comparison between the signal being applied to the power supply and the measured input signal associated with the remote device, indicated by the electrical signal measurement, whether the remote device is electrically associated with the power supply.

A method for detecting if a power supply is associated with a remote power providing device upstream of the power supply, the method comprising:

• using a controller having machine readable, non-transitory executable code running thereon to vary a characteristic of a signal being applied to an input of the power supply;
• using the controller to:
• compare a measurement obtained from a measurement subsystem relating to a characteristic of an output signal associated with the remote power providing device with the signal being applied to the input of the power supply, to determine whether the remote power providing device is electrically associated with the power supply;
• and
• wherein said varying a characteristic of a signal being applied to the input of the power supply comprises using the signal to instruct the power supply to vary its input power factor, and the characteristic is a magnitude of change of the input power factor.
