POWER LOSS MEASURING SYSTEM FOR MEASURING POWER LOSS AT HARMONIC FILTER INCLUDED IN HIGH VOLTAGE DIRECT CURRENTHVDC STSTEM AND METHOD FOR MEASURING POWER LOSS THEREOF

摘要

A lossy power measurement system for measuring lossy power in a harmonic filter included in a high voltage direct current transmission system is disclosed. The present loss power measuring system calculates a loss of the harmonic filter using a harmonic filter including a plurality of elements, a monitoring sensor unit for detecting impedance changes of the plurality of elements, and an amount of change in impedance of the plurality of elements. It includes a control unit.
