Problems solved by technology

[0004] The manual fault location method is that when a fault is detected, the fault indicator will turn over and give an alarm, and the fault section will be located by manual line inspection. However, the manual line inspection is slow, resulting in long power outages;
[0005] The fault host location method is that when a fault is detected, the fault indicator turns over and gives an alarm, and the alarm information is transmitted to the fault location system through the communication network. The fault location system displays the fault information after receiving it. The fault location system is installed in the duty room , requires on-duty personnel to monitor it 24 hours a day, which is time-consuming and labor-intensive, and takes up human resources

Abstract

The invention discloses a fault positioning system and method for an overhead power distribution line. The fault positioning system comprises fault indication units, fault monitoring units and mobile intelligent fault positioning terminals, and is characterized in that the fault indication units are used for acquiring and monitoring load information and line fault information of the power distribution line and transmit the load information and the line fault information to the corresponding fault monitoring units through wireless local area communication networks; the fault monitoring units are used for receiving the load information and the line fault information which are transmitted by the power distribution fault indication units, and sends remote measurement packets and fault information short message packets to the corresponding mobile intelligent fault positioning terminals through a wireless wide area communication network; and the mobile intelligent fault positioning terminals are used for performing information interaction with the power distribution fault monitoring units, realize monitoring for the power distribution line, execute a fault positioning strategy so as to realize fault section positioning, carry out positioning according to topological graph and display fault information. The fault positioning system disclosed by the invention gives an alarm timely when a fault emerges and displays a fault positioning section, thereby reminding the maintenance personnel to process in time, being convenient for quick rush repair for faults, greatly improving the operation and maintenance efficiency, and having good application prospects.

Description

technical field [0001] The invention relates to the technical field of fault location for power distribution systems, in particular to a fault location system and method for overhead power distribution lines. Background technique [0002] In the power distribution system, especially for overhead distribution lines, when a short-circuit fault or ground fault occurs, it is necessary to accurately locate the faulty line section and disconnect the faulty section, so as to restore the power supply of the non-faulty section in time, which can save a lot of energy. Working hours, reducing outage time and outage range. [0003] At present, the existing fault location system is divided into two methods: manual fault location and fault location system, as follows: [0004] The manual fault location method is that when a fault is detected, the fault indicator will turn over and give an alarm, and the fault section will be located by manual line inspection. However, the manual line ins...
