ABSTRACT:
Autotransformer design which is capable of modifying the active power flow in autotransformers connecting two different voltage systems in an electrical substation. The bus-tie autotransformers presented change the active power flow by modifying the phase-angle between the primary and secondary voltages of the autotransformer. In accordance with the two tap changers are employed allowing for independent changes in both the voltage ratio and the phase-angle values.
