Cross current compensation control system for a power system

A cross current compensation control system for a power system, comprising:

• first and second current transformers disposed at the respective secondary sides of first and second power transformers connected to the same power supply;
• a cross current detection compensator connected to a cross connection line that cross-connects the secondary sides of the first and second current transformers;
• a first voltage adjusting device connected to a first bus bar connected to the secondary sides of the cross current detection compensator and the first power transformer;
• and
• a second voltage adjusting device connected to a second bus bar connected to the secondary sides of the cross current detection compensator and the second power transformer,
• wherein:
• the cross current detection compensator outputs a compensation voltage when detecting a cross current that circulates within the first and second power transformers, the first and second bus bars and a switch that connects the first and second bus bars;
• the first voltage adjusting device controls the voltage adjustment tap at the secondary side of the first power transformer on the basis of the voltage of the first bus bar and the compensation voltage;
• and
• the second voltage adjusting device controls the voltage adjustment tap at the secondary side of the second power transformer on the basis of the voltage of the second bus bar and the compensation voltage.
