输电线路动态增容系统的设计

本文研发了基于环境信息和导线温度的动态增容监控系统，在不突破现有技术规程的条

Abstract: An on-line monitoring system of dynamic capacity-increase of transmission lines has been developed, by which the capacity of transmission lines can be increased in the precondition that the present specifications of conductors remain unchanged. The master and slave monitoring units were firstly adopted to measure the conductor temperature, the ambient temperature, the wind speed, and the solar radiation intensity by wireless communication, and these data were sent to the municipal monitoring and controlling center by GSM SMS. The latent capacity was calculated by mole formula. The hardware design and software design of the master and slave monitoring units, the program of digital temperature sensor named DS18B20, and the design of expert software were introduced in this paper.
