Automatic detection system and method for distribution line fault indicator

Abstract

The invention provides an automatic detection system and method for a distribution line fault indicator. The system is composed of an information acquisition module, a detection control module and a detection work module. The information acquisition module identifies and collects basic attribute information of a detected fault indicator automatically and transmits the collected to the detection control module; the detection control module configures a detection use case, generates a control instruction of the detection work module, and generates a detection report according to the basic attribute information, transmitted by the information acquisition module, of the detected fault indicator; and the detection work module receives the control instruction issued by the detection control module, outputs a detection signal in real time, injects the detection signal into the detected fault indicator automatically, and transmits operation information and response information of a distribution line fault indicator to the detection control module automatically according to a detection result. Therefore, batched detection of fault indicators is realized; the item is detected comprehensively; and the detection efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the detection of a distribution line fault indicator, in particular to an automatic detection system and method for a distribution line fault indicator. Background technique [0002] In the distribution network system, there are many branches and complex operation conditions. When a short circuit or ground fault occurs, it is difficult to determine the fault section (location), which brings great difficulties to the maintenance work. The distribution line fault indicator is a device installed on the distribution line to monitor line operating parameters, detect and indicate various short circuits and ground faults, and send monitoring information and fault detection data to the main power distribution station. When a line fault occurs, the fault section is determined in time, which greatly shortens the time for finding the fault section, and provides a strong guarantee for quickly troubleshooting and restoring normal power supp...

Problems solved by technology

At present, for the detection of various types of distribution line fault indicators, the degree of automation is low. The existing detection systems and methods mainly include RTDS simulation, protection devices, and true type detection systems. However, the use of RTDS simulation tools has poor load capacity. It is easy to be distorted, the number of batch detection is small, and the efficiency is low; the use of protective devices cannot accurately simulate the transient characteristics of ground faults, especially the detection ability of single-phase ground faults in small current grounding systems is poor; the use of primary equipment is directly built The experimental environment covers a large area, has few testing items, poor flexibility and high risk
