Power control system for power transmission equipment using solid state switching devices

A power control system for power transmission equipment, the system comprising:

• a plurality of solid state on-load tap changers (SSOLTCs) electrically coupled to a phase of the power transmission equipment;
• a sensor device configured to measure a parameter associated with power flowing through the phase of the power transmission equipment;
• and
• a controller communicably coupled to the plurality of SSOLTCs and the sensor device, wherein the controller is configured to:
• obtain a measurement of the parameter associated with power flowing through the phase of the power transmission equipment from the sensor device at a point in time;
• determine, based on the measurement and at the point in time, that the parameter falls outside an acceptable operating range based on a current configuration of the plurality of SSOLTCs;
• identify a target configuration of the plurality of SSOLTCs that, when implemented, results in the parameter returning to the acceptable operating range;
• and
• operate one or more of the plurality of SSOLTCs to achieve the target configuration at the point in time.
