Rapid monitoring and alarming system of faults of power transmission circuits

Abstract

The invention discloses a rapid monitoring and alarming system of faults of power transmission circuits. The system comprises a monitoring system platform. Bidrectional connection is achieved betweenthe monitoring system platform and a fault acquisition unit. The fault acquisition unit is formed by N sub-acquisition modules. Bidirectional connection is achieved between the monitoring system platform and an external network communication transmission system. The external network communication transmission system comprises a sharing information collection module, a sharing information integration module and a sharing information carrying module. The invention relates to the technical field of electric power monitoring. According to the invention, well fault monitoring of power transmissioncircuits in the region can be achieved; it is achieved that internal and external network communication and data transmission can be performed between towers; through a tower fault monitoring unit which is closest to a main station, information is sent to the main station, so alarming processing is performed; objectives of seizing the first-aid repairing opportunity and shortening power supplyingrecovering time are achieved; repairing efficiency is greatly improved; and reliability of power supply is ensured.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a rapid monitoring and alarm system for transmission line faults. Background technique [0002] The transmission line is the lifeblood of the power system. It is responsible for the transmission of electric energy. With the increasing scale of the power system, the number of high-voltage, high-energy, and long-distance transmission lines is increasing. Once the transmission line fails, it will affect the safety of the power system. Operation, industrial and agricultural production, and people's daily life are also increasingly affected. Therefore, it is very important to ensure the safe operation of transmission lines. The high-voltage and ultra-high-voltage transmission lines on the grid are very long, and some are hundreds of kilometers long. Some are even as long as thousands of kilometers, and they are distributed in a wide area. The insulators on the transm...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fast monitoring and alarm system for transmission line faults, which solves the problem that it is impossible to perform good fault monitoring on transmission lines in remote areas with sparse pole towers, and it is impossible to perform internal fault monitoring between each pole tower. Network communication and data transmission, and then sent to the main station for alarm processing through the tower fault monitoring unit closest to the main station, which cannot achieve the purpose of seizing the first emergency repair opportunity and shortening the power supply recovery time
