High voltage direct current (HVDC) transmission system to compensate for voltage values output from a plurality of potential transformers

A high voltage direct current (HVDC) transmission system to compensate for voltage values output from a plurality of potential transformers, the HVDC transmission system comprising:

• an integrated measurement panel including memory storing a plurality of compensation values each corresponding to one of the plurality of potential transformers, the integrated measurement panel configured to be connected to and disconnected from the plurality of potential transformers;
• and
• an HVDC transmission device connected to the integrated measurement panel and the plurality of potential transformers when the plurality of potential transformers are disconnected from the integrated measurement panel, the HVDC transmission device including:
• a deviation compensator configured to:
• detect a plurality of voltage values output via the plurality of potential transformers when the plurality of potential transformers are connected to the integrated measurement panel;
• receive the plurality of compensation values from the integrated measurement panel;
• measure a plurality of actual voltage values corresponding to the plurality of potential transformers;
• and
• compensate the measured plurality of actual voltage values based on the plurality of compensation values;
• and
• a central controller configured to control operation of the HVDC transmission device based on the compensated plurality of actual voltage values,
• wherein the integrated measurement panel is configured to determine a compensation value for a new potential transformer based on the plurality of compensation values when the new potential transformer is connected to the HVDC transmission device.
