Abstract
The present disclosure relates to system and method used to transmit power to a remote location. More specifically, the present disclosure relates to a system and method used to independently energize control and monitoring functions of a remote installation prior to and/or during energizing its main circuit.
Claims22
A system for energizing an auxiliary system supporting operation of a main load, both located at a remote location, the system comprising:
- three long-distance current-carrying conductors running between a nearby location and the remote location configured to supply high-voltage three-phase electrical power for rotating the main load;
- a step-up transformer at the nearby location configured to increase voltage of the three-phase electrical power for transmission over the three long-distance conductors;
- a step-down transformer at the remote location configured to decrease voltage of the three-phase electrical power from the three long-distance conductors for use by the main load;
- an auxiliary power supply system located at the nearby location configured to transmit auxiliary electrical power on the three long-distance conductors;
- and
- an auxiliary power extraction system located at the remote location configured to extract electrical power that is transmitted on the three long-distance conductors and to energize the auxiliary system with said extracted electrical power.
3 more elements
A method for energizing an auxiliary system supporting operation of a main load, both located at a remote location, the method comprising:
- transmitting auxiliary electrical power from a nearby location to the remote location over three long-distance conductors running between the nearby and remote locations which are configured to supply high-voltage three-phase electrical power for rotating the main load;
- and
- at the remote location extracting auxiliary electrical power being transmitted over the conductors and energizing the auxiliary system with the extracted electrical power.
