Abstract	In recent years, extremely bad weather occurs frequently and the accumulation of ice on high voltage AC transmission lines renders mechanical and electrical damages to these lines. They greatly influence electrical power system normal operation; therefore, the de-icing technology has been highly regarded. Given the constraints of current thermal, mechanical and spontaneous ice-melting method, this paper that compare with previous incomprehensive papers firstly puts forward a full DC de-icing scheme, which contains all the deicing system parameters such as de-icing current, the filter capacity in AC side of rectifier. The scheme is similar to a three-phase half controlled bridge rectifier circuit and able to calculate all the parameters while taking AC system operation modes into consideration. All the parameters calculate is based on the fundamentals of electrical circuits and power electronics. A simulation model deploying PSCAD/EMTDC software under typical operation conditions of power systems proves that this scheme is capable of getting a de-icing current with a fast stabilizing speed and gaining good de-icing result. When there is a short circuit fault on AC ice-accumulated transmission lines, the smoothing reactor can suppress the short current effectively as well as guarantee the power quality of electrical loads.
