Natural Disasters Prevention of Power Communications System

Natural disasters of China mainland mainly include earthquake disaster, geological disaster, sandstorm, typhoon, flood, thunderbolt, snowstorm, low-temperature sleet and freezing. For enhancing the emergency response capacity of power communication network, impact of the natural disasters on power communication facilities was analyzed. The disasters categories and distribution were introduced. China power communication network includes wire communication and wireless communication technology. For instance, optical fiber, power line carrier and microwave. The different communication technology's capacity of resistance to natural disasters was analyzed and compared. Conceptual paradigm for disaster digital simulation model was introduced. And disaster direct loss estimation method based on property loss rate model is proposed. The measures for enhancing emergency response capacity of power communication network are explored. Successful cases of withstanding blizzard and earthquake disaster in 2008 are also illustrated.
