Intelligent 10-kV line tripping false alarm judging implementation method

Abstract

The invention provides an intelligent 10-kV line tripping false alarm judging implementation method. The intelligent 10-kV line tripping false alarm judging implementation method comprises the following steps that 1, content that a tripping condition filling module needs to fill in is determined; 2, a 10-kV line tripping criterion and rule are determined; 3, interfaces for achieving resource sharing among distribution network monitoring systems are established and broken through, and related information of line tripping is extracted and matched and verified with filling information; 4, tripping information reported by units is judged according to the made judging rule, and in the tripping condition filling module, a system selects 'false alarms' and fills in 'false alarm types'; and 5, the intelligent judging system conducts judging according to the conditions such as a current curve acquired by the system, an SOE accident record uploaded by a protection device, the distribution transform outage condition and the like to enter an artificial intelligent assessment process, and the system obtains outage, cancellation, transmission testing and tripping through algorithm calculation and intelligent retrieval. According to the method, by calling related data of the systems for comparative analysis, subjective factors such as non-objectiveness, misjudgment and the like which are brought by artificial judgment are greatly reduced.

Description

technical field [0001] The invention relates to a method for realizing an intelligent judgment of 10kV line tripping false alarm, which belongs to the technical field of power grid fault evaluation. Background technique [0002] In recent years, due to the intensification of urban power grid construction, the level of the main grid structure has been greatly improved. However, due to the complex structure of the 10kV urban distribution network, the low level of distribution network automation, the quality of devices and external interference and other factors, the distribution network The line trip rate remains high, and the provincial companies have also increased the assessment of the 10kV line trip rate index, and included it in the benchmarking index of the same industry. The power supply units have made great efforts to reduce the trip rate, but it is inevitable There is a phenomenon that normal trips are artificially reported as false positives, resulting in more and m...

[0002] In recent years, due to the intensification of urban power grid construction, the level of the main grid structure has been greatly improved. However, due to the complex structure of the 10kV urban distribution network, the low level of distribution network automation, the quality of devices and external interference and other factors, the distribution network The line trip rate remains high, and the provincial companies have also increased the assessment of the 10kV line trip rate index, and included it in the benchmarking index of the same industry. The power supply units have made great efforts to reduce the trip rate, but it is inevitable There is a phenomenon that normal trips are artificially reported as false positives, resulting in more and more false positives. The quality of reporting through human judgment is huge, and it is easy to cause misjudgments due to subjective factors. Quickly and accurately judge the quality of the 10kV trip false alarm information and whether there is a false alarm in the information, which requires the design of a judgment principle and the use of intelligent algorithms to objectively evaluate the trip false alarm information
