摘要:随着智能电网概念的提出、发展,以及电网运营管理工作不断深入的向科技化、综合化、自动化、智能化发展,输电线路的维管工作内容变得越来越繁杂。论文从当前供电系统自身的通信条件、资源和维管区输电线路的现状出发,设计了基于5.8C载波OFDM调制的输电线路无线网络覆盖系统,给出了系统整体框架,提出采用完余路径的无线网络连接方法、基于优先级和自动认证的网络越区切换方法,最后设计了基于5.8G载波OFDM调制的输电线路状态监测装置。仿真结果说明了上述系统的可行性和有效性。该系统的使用可以大大降低系统的运营费用,又可以严格保证数据的保密性和安全性,使通信系统的覆盖地域更为广泛,组网方式更为灵活。

With the emergence and development of the concept of smart grid, and with the deepening of power grid operation management the work to the science and technology, integration, automation and intelligent development, the maintenance and management work of the transmission line is becoming more and more complicated.Based on the curent power supply system's own communication conditions,The present status of resources and maintenance and management area, The thesis proposed a wireless net-work coverage system of transmission line based on 5. 8G carrier and OFDM modulation and given the o-verall framework. Then, it proposed the wireless network connection method based on redundant paths and the network handoff method based on priority and automatic authentication. Finally, the transmis-sion line condition monitoring devices based on 5. 8G carier OFDM modulation is given. Simulation re sults prove the feasibility and effectiveness of the system. The use of this system can greatly reduce the operating cost of the system, and ensure strictly confidentiality and security of data at the same time, so
that make its geographical coverage more extensively, and make networking more flexible. Key words: 5. 8G carrier; OFDM Modulation; Wireless Network Coverage; Handover
