Ice-melting system capable of automatically adjusting output current according to iced line temperature

Abstract

The invention relates to an ice-melting system capable of automatically adjusting output current according to iced line temperature. The system comprises an iced line, which is led out from the DC side of an ice-melting power supply module, and is connected with a temperature site monitoring sensor module for obtaining conductor temperature data of the iced line and an icing site monitoring sensor module for obtaining conductor external diameter data of the iced line; the temperature site monitoring sensor module, which is in both-way connection with a temperature fiber grating adjusting module; the icing site monitoring sensor module, which is in both-way connection with an icing fiber grating adjusting module; the temperature fiber grating adjusting module and the icing fiber grating adjusting module are connected with a monitoring calculation module; and the monitoring calculation module is connected with the ice-melting power supply module. The ice-melting system capable of automatically adjusting the output current according to the iced line temperature can adjust the output current of an ice-melting power supply according to the temperature of the iced line, and has the advantages of automatic adjustment, quick communication, remote transmission and severe environment adaptation and the like.

Description

technical field [0001] The invention relates to an SVC voltage regulator for a power transmission system, in particular to an ice-melting system that automatically adjusts output current according to the temperature of an ice-covered line. Background technique [0002] The icing of transmission lines in winter is one of the natural disasters of the power system. When the icing is serious, the line will be disconnected, the pole / tower will fall, resulting in a large-scale power outage, and the repair work is difficult, long-term, and wide-ranging. Therefore, in order to cope with the serious threat of ice and snow disasters to the power system infrastructure, the research on the ice melting technology of transmission lines has been strengthened at home and abroad. [0003] At present, the more widely used deicing and ice-melting devices are DC ice-melting devices. The basic principle of DC ice-melting devices is to convert AC power into DC power, and then load the DC power t...

Problems solved by technology

If the melting effect of the ice-covered line is found to be poor during the ice-melting process, it is necessary to manually operate the DC ice-melting device to increase the ice-melting current of the line; The danger of burning the line requires manual operation of the DC ice-melting device to reduce the ice-melting current of the line. The above ice-melting process requires manual operation and the use process is cumbersome
