Abstract

See full text

A method and a system for controlling an on-load tap changer of a transformer during reverse power flow includes determining a loss ratio factor using voltage and current values for each of a primary side and a secondary side of a transformer. Further, the method comprises determining a relative strength of a first source connected to the primary side and a second source connected to the secondary side of the transformer based on the loss ratio factor. Thereafter, transmitting a control signal to an on-load tap changer of the transformer to regulate voltage on the primary side or on the secondary side of the transformer based on the relative strength of the first source and the second source.
