Problems solved by technology

The method of manual search takes a lot of time and the fault cannot be eliminated in time, which will cause a waste of resources and extremely bad social effects. If the fault is a multi-point fault, the efficiency will be even lower
In summary, the traditional manual method of directly finding the fault point is time-consuming, laborious, inefficient and wastes resources, and it is difficult to meet the requirements of the rapid development of modern industry

Embodiment 1

[0023] Follow these steps:

[0024] (1) Create a fault finding system: Install multiple fault indicators and multiple communication terminals on the power line. The fault indicators are used to find line fault information. Three fault indicators on three phase lines at the same detection position are combined into one group Fault indicator, the communication terminal is used to transmit the information of nearby fault indicators to the monitoring center, the signal output terminal of the fault indicator is connected to the signal input terminal of the communication terminal, the wireless communication connection between the communication terminal and the monitoring center, the communication terminal to The alarm information sent by the monitoring center includes the address information of the fault indicator and the fault type information.

[0025] (2) The monitoring center creates a software-based topology map. The fault indicator and communication terminal in the topology ma...

Abstract

The invention discloses an automatic monitoring method for a power system line fault. The method comprises the following steps: (1) a fault finding system is established: a plurality of fault indicators and a plurality of communication terminals are installed on a power line; (2) a monitoring center establishes a topological graph based on software, wherein the fault indicators and the communication terminals in the topological graph respectively have address information with the unique numbers; (3) the monitoring center establishes a set F[M][N] of all the fault indicators in the line; (4) the monitoring center establishes a branch warning information set B[D][E]; (5) an effective warning information set G[H] is established; (6) management personnel are informed of all effective warning information in the G[H], the steps (4), (5) and (6) are repeated, or the monitoring center waits, and the automatic monitoring of the power system lien fault is achieved. By means of the automatic monitoring method for the power system line fault, effective warning information of the power line is effectively monitored, and the management personnel is informed of the information, time and labor are saved, efficiency is high, social effect is good, false alarming is avoided, and the requirement for fast development of modern industries is met.

Description

technical field [0001] The invention relates to a method for finding faults in power system lines, in particular to an automatic monitoring method for power system line faults based on electronic equipment and software applications. Background technique [0002] In the power system, if a short circuit or a ground fault occurs, manual direct search for the fault point is adopted. Locating the location of the fault requires personnel to check each line on all lines to find the fault. The method of manual search takes a lot of time and the fault cannot be eliminated in time, which will cause a waste of resources and extremely bad social effects. If the fault is a multi-point fault, the efficiency will be even lower. To sum up, the traditional manual method of directly finding fault points is time-consuming, laborious, inefficient and wastes resources, which is difficult to meet the requirements of the rapid development of modern industry. Contents of the invention [0003] ...
