Problems solved by technology

[0002] At present, transmission line fault diagnosis is mainly based on manual judgment based on the work experience of line operation and maintenance personnel. The judgment results vary from person to person. The diagnosis level is closely related to the work experience and business ability of the diagnosis personnel, and it is difficult to improve the judgment based on pure manual experience. automatic diagnosis level

Embodiment Construction

[0016] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 As shown, the automatic judgment method of transmission line icing fault includes:

[0018] Step S100, obtain the basic information of the transmission line fault according to the fault recording information, and the specific input parameters include: tripping line name, tripping time, protection action status, fault phase difference, reclosing action status, wave recording distance, pole number calculated by wave recording , Guidance line checking range, etc.

[0019] Step S200: Input the basic information of the transmission line fault into the processing device, the processing device stores the data that causes the icing trip, and the processing device compares the basic information of the transmission line fault with the data that causes the icing trip as follows : Judging whether it is an i...

Abstract

The invention relates to a method for automatically judging an electric transmission line icing fault. The method comprises the first step of acquiring basic information of the electric transmission line fault according to fault recording information; the second step of judging whether icing tripping exists or not according to the basic information of the electric transmission line fault, wherein if yes, the third step is executed, and if not, the fourth step is executed; the third step of judging the type of the icing tripping; the fourth step of determining fault reasons according to the type of icing tripping, wherein if the fault reasons can be determined, the sixth step is executed, or otherwise, the fifth step is executed; the fifth step of outputting fault line patrol guiding ideas, and the second step is executed after the patrolling information is obtained; the sixth step of outputting a diagnostic report. Compared with an existing people experience judging method, the method has the advantages that the speed and efficiency of judgment are improved, the judgment result is more objective and meets a criterion, and a favorable basis is established for electric transmission line malfunction judgment of a computer.

Description

technical field [0001] The invention relates to the determination of transmission lines in electric power operation and maintenance, in particular to an automatic determination method for icing faults of transmission lines. Background technique [0002] At present, transmission line fault diagnosis is mainly based on manual judgment based on the work experience of line operation and maintenance personnel. The judgment results vary from person to person. The diagnosis level is closely related to the work experience and business ability of the diagnosis personnel, and it is difficult to improve the judgment based on pure manual experience. Automatic diagnosis level. Therefore, it is necessary to study a method that can objectively, efficiently and automatically determine the icing fault of transmission lines. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a method for autom...
