Abstract:

The scientifical and reasonable partition for the level of icing zones along power transmission lines plays a key role for the safe and stable operation of power grid. Based on the analysis of the status of icing distribution map along transmission lines at home and abroad, the related techniques were discussed, including the measurement methods for icing, the numerical simulation of icing thickness, the mathematics statistical model, the partition standards, the treatment of microtopography and microclimate, the adjustment for operation experience, as well as the drawing technique of icing distribution map. According to the existing problems of the icing distribution map drawing and the construction planning of power grid, the development trend of the key drawing techniques of icing distribution map were proposed.

Key words: icing distribution map, power transmission line, icing measurement, numeric simulation, statistical model, partition standard, microtopography and microclimate
