| Abstract: | The DC de-icer is an effective device to melt ice on overhead lines and can well improve the ability of power grid resisting frozen disaster. This paper does investigation on several issues in theory and application of the DC de-icer, including its control and protection functions, de-icing mode with AC lines, open line test mode, zero power test mode, active and reactive power characteristics, harmonic characteristics, and AC line resonance over-voltage as to provide reference for the DC de-icer applying to actual grids. |
