Abstract

The invention relates to a system for online monitoring faults of an electric power line. The system comprises a remote terminal device and a monitoring master station, wherein the remote terminal device comprises a fault indicator and a line fault data collector which are in communication connection by an RF (radio frequency) network, the monitoring master station comprises a handheld mobile terminal and a microprocessor control terminal, the line fault data collector communicates with the data receivers of the handheld mobile terminal and the microprocessor control terminal through a GSM/GPRS (global system for mobile/general packet radio service) communication module by a mobile communication network, and the upper computer of the microprocessor control terminal communicates with the handheld mobile terminal through a GSM/GPRS generating and receiving data module of the data receiver by the mobile communication network. According to the system, intelligent monitoring is realized; in the manners of on-site indication and remote fault alarm, the fault types and fault points are confirmed, the faults are located accurately and timely; as two terminals are adopted, the faults are alarmed timely, reasonable dispatch is realized, the fault elimination efficiency is improved, and the power distribution reliability is improved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an online fault monitoring system for electric power lines used for real-time monitoring of faults in field overhead lines. Background technique [0002] The transmission line is the lifeblood of the power system, and it is responsible for the transmission of electric energy. With the increasing scale of the power system and the increasing number of high-voltage, high-energy, and long-distance transmission lines, once the transmission line fails, it will have a greater impact on the safe operation of the power system, industrial and agricultural production, and people's daily life. , so it is very important to ensure the safe operation of transmission lines. [0003] The high-voltage and ultra-high-voltage transmission lines on the power grid are very long, some are hundreds of kilometers long, and some are even thousands of kilometers long. Its distribution area is wide...
