Transformer power management controllers and transformer power management methods

A transformer power management controller comprising:

• processing circuitry configured to:
• access a reference value of an electrical characteristic of electrical energy at a secondary of a transformer of an electric power system and which corresponds to a known amount of power which is being supplied by the secondary of the transformer;
• access a relationship between the electrical characteristic and an amount of power being supplied by the secondary of the transformer;
• access another value of the electrical characteristic at a moment in time when the electrical energy is being supplied to at least one load which is coupled with the secondary of the transformer;
• determine a plurality of additional values of the electrical characteristic at a plurality of additional moments in time when the electrical energy is being supplied to at least one load which is coupled with the secondary of the transformer;
• and
• use the reference value, the relationship, the another value, and the additional values to adjust an amount of the electrical energy which is supplied by the secondary of the transformer to at least one load which is coupled with the secondary of the transformer at a plurality of respective moments in time.

A computer-implemented transformer power management method comprising:

• using a secondary of a transformer of an electric power system, supplying electrical energy to a plurality of loads which are coupled with the secondary of the transformer;
• adjusting an amount of the electrical energy which is supplied to one of the loads to determine a relationship between a change in voltage of the electrical energy being supplied by the secondary of the transformer and a change in power being supplied by the secondary of the transformer;
• monitoring the voltage of the electrical energy being supplied by the secondary of the transformer to determine a reference value of the voltage of the electrical energy being supplied and which corresponds to a known amount of power being supplied by the secondary of the transformer;
• monitoring the voltage of the electrical energy to determine another value of the voltage at a moment in time while the secondary of the transformer is supplying the electrical energy to at least one of the loads;
• using the relationship between the change in voltage and the change in power, the reference value and the another value, determining an amount of power which is being supplied by the secondary of the transformer to the at least one of the loads at the moment in time;
• using the determined amount of power, reducing the amount of the electrical energy which is supplied by the secondary of the transformer to the at least one of the loads;
• and
• wherein the monitoring of the voltage of the electrical energy to determine the another value occurs after the monitoring of the voltage to determine the reference value and after the determination of the relationship.
