Abstract	The transmission line de-icing method based on adjusting electric load is studied by using controllable inductor and capacitor compensation, in order to reduce and avoid the impact of the freezing rain and ice disaster. The technical and economic feasibilities of various ice-melting methods are briefly compared and analyzed between inductor-adjusting-load, short-circuit and over-current. The theoretical models and calculations of inductor-adjusting-load are proposed. The implementing method of inductor-adjusting-load for connecting transmission lines is given based on 220kV Xinghua Primary Substation 66kV System in Jixi Electric Power Bureau. The calculation of de-icing current and volume of controllable inductor are also given. The key equipment and the necessity of applying inductor-adjusting-load technique are described and discussed. In conclusion, the inductor-adjusting-load method is practical in technology and feasible in economy.
