Temperaturc Of Power Transmission Lines On-Line Monitoring System Design

Existing power system is a combination of the different functions of generation, transmission, substation, distribution, electricity equipment. Transmission lines as the main way of long-distance transmission of electricity is an important part of the power system and its operation state can affect the security and stability of the entire power grid operation. Can not only understand the operation of the front-end transmission line conductor line temperature monitoring of transmission lines, but also a comprehensive collection and long-term accumulation of dynamic capacity, over-load test and load section live wire, heavy ice, the melting ice of the AC and DC focus the area of real-time temperature data for transmission lines to provide the real basis of data in the design, operation and maintenance. The temperature of transmission line online monitoring technology development and promotion, not only can accelerate our transmission line management information, networking, and intelligent, but also an important part of China’s "strong smart grid" construction.First, the paper describes the purpose and significance of the study conductor temperature online monitoring technology, and then introduces the development status of the technology at home and abroad.Secondly, the paper discusses the structure of the transmission line conductor temperature online monitoring system, functionality, and system requirements, as the same time the paper designs the framework of the entire transmission wire temperature monitoring system, and the framework’function is given.Again, the paper combined with the demand of the transmission line conductor temperature monitoring system, designed the wireless sensor network as the access network, EPON, GPRS and broadband wireless network as the remote communication backbone network. Multi-technology heterogeneous converged networks can be better to meet the demand of the transmission line conductor temperature monitoring system.Finally, this paper the combine with the structural framework of transmission line conductor temperature monitoring system to analysis the temperature collection terminal and the host temperature requirements, at last the paper designs the hardware and software systems.
