Emergency Communication for Electric Power System Based on Airship

The problems facing the communication for electric power system safety were recently highlighted by ice disaster in southern China and Wenchuan earthquake. The existing communication systems in the Yunnan power grid are far from adequate. Terrestrial networks are disabled by serious natural disaster. Satellite communication network is deficient in bandwidth, and has high propagation delay, which cannot satisfy the demand of communication for electric power system. Therefore, a novel communication system is urgently needed in electric power system. In this paper, we proposed a project of emergency communication for electric power system based on airship, and a trial experiment was carried out in Qu Jing City of Yunnan Province, China. We show that the emergency communication for electric power system based on airship is practicable. A perfect integrated communication system based on high-altitude platforms (HAPs) was described.
