电力系统应急通信网络及其抗毁性分析

Emergency Communication Network in Power System and Its Invulnerability Analysis

针对当前电力系统应急通信的实际需求,提出了具有3层结构和2个数据共享中心的电力应急通信网络框架。依托电力系统现有通信网络资源,充分利用微波存取全球互通(WIMAX)技术和卫星通信车载技术,设计了网省公司与地、市级电力公司(变电站)之间的应急通信网络。介绍了网络连通度和虚拟节点的概念,阐述了基于连通度的网络抗毁性评价模型。利用该评价模型对比分析了设计的电力应急通信网络和现有电力通信网络的抗毁性能,证明了电力应急通信网络的优越性。

Considering practical demand, of current emergency communication in power system, a frame of emergency communication network for power system, which consists of a 3-1ayer structure and possesses two data sharing centers, is proposed. Based on existing resources of communication network in power system and fully utilizing worldwide interoperability for microwave access （WIMAX） technique and satellite communication in-vehicle technology, an emergency communication network among provincial power corporation, regional power companies and urban power companies is designed. The concepts of network connectivity and virtual node are presented, and a connectivity-based invulnerability evaluation model of communication network is expounded. By use of the connectivity-based invulnerability evaluation model, the invulnerability of the designed emergency communication network in power system and that of the existing emergency communication network in power system are compared and analyzed, thus the superiority of emergency communication network for power system is validated.
