Analysis for DC transmission line harmonics originated from AC transformer inrush current and improved method for DC harmonic protection

Large-scale electricity has fed into Central and Southern China through DC transmission lines. Any one of the DC transmission lines suddenly outage will result in a large proportion of power-shortage. Recently, there are many DC harmonic protection misoperations caused by AC disturbance, resulting i...
