英文摘要：

The power communication system is the key support of smart grid to control the information flows, realize intelligent power system. The performance of power communication network directly affects the reliable operation of the power system. Based on complex network theory, this paper analyzed the power communication backbone network. By establishing the static and dynamic measures, we proposed a novel algorithm to identify the critical elements and the weak areas. By calculating one of the actual power communication optical networks, the algorithm＇s correctness is proved. The algorithm provides a new technical support to improve the operation and management of electric power communication network. It also has important signifi cance to ensure the reliability of power system and reduce the occurrence of large-scale power network accidents.
