Abstract

An online dynamic capacity-increase system of transmission lines is produced, by which the dynamic capacity-increase of available transmission lines can be increased with no break of available rules. The slave monitoring unit is designed to measure the conductor temperature which is sent to the main monitoring by wireless communication. The master monitoring unit is designed to measure the ambient temperature, the wind speed, and the solar radiation intensity, and these data including the conductor temperature are sent to the municipal monitoring and controlling center by GSM SMS/GPRS. The latent capacity can be calculated by mole formula. The hardware design and software design of the master and slave monitoring units, and the design of expert software are introduced in this paper.
