In recent years,ice disaster on power grid occurs frequently. Numerous main transmission lines are forced to stop operating over a long period of time, and there is significant challenge posed on stable operation of the power grid and reliable power supply. Combined with the experience in fighting against ice disaster, this paper analyzes anti-ice disaster countermeasures in this region. The paper proposes technical means like the concept of life channel, planning of constructing life channel in regional power grid and key factors for stabi-lization of isolated grid operation. Meanwhile, the paper summarizes problems in selection of transmission line corridor, power grid planning, power planning exposed in the ice disaster; besides, it brings forward im-provement suggestions.
