Emergency Management for the Ice Disaster in Power Grids and Some Suggestions

From January 2008 to February 2008,many provinces of Southern China encounter the rare sleet and freezing weather,which results in the serious transmission line icing,and cause the frequent occurrences of many serious accidence such as transmission line broken,electrical wire pole/tower falling down and so on,moreover,many backbone transmission lines are forced to be out of running.The stable operation of power systems and reliable power supply are faced with huge challenges.Jiangxi province is one of the seriously affected provinces.In this paper,the forming and developing process of ice disaster of Jiangxi power grid are briefly introduced,and the experiences of and lessons from the power grid emergency management are summarized.Some suggestions are brought forward to the disaster-combat and preventive work of power grids,the stable operation and control of power systems,power grid development and planning,and power plant distribution and planning.
