Embodiment Construction

[0023] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the present invention provides a method for judging the tripping of line faults affected by meteorological disasters, comprising the following steps:

[0025] Step 1, integrate the line fault tripping information of the EMS system, the protection action and fault distance measurement information of the protection information system, the primary and secondary equipment action information of the equipment monitoring system, etc., to identify the line switch fault tripping, and exclude manual operation and line maintenance, etc. Misjudgment caused by fault trip; among them, the line fault trip information of EMS system, including fault time, fault equipment, fault phase, fault distance, reclosing action and other information;

[0026] In the above step 1, there is a possibility of misreporting if only the dis...

Abstract

The invention discloses a method for judging a line fault trip affected by meteorological disasters, including the following steps: identifying a line switch fault trip according to the line fault trip information of an EMS system, the protection action and fault ranging information of a protection information system and the action information of the primary and secondary equipment of an equipmentmonitoring system; analyzing the causes of the line fault trip according to the surrounding meteorological information of a line tower, the GIS space information of the line tower and the anti-disaster capacity of the line equipment; and automatically generating a fault report of the line fault trip by considering the primary equipment action, secondary equipment action, fault waveform, load loss, power flow transfer and equipment state information before and after the fault. Through the method, when a grid line has a fault trip, the fault can be located quickly, and fault trip misjudgment can be eliminated. Moreover, the causes of the fault can be preliminarily analyzed according to the meteorological disaster information and the anti-disaster capacity of the equipment, and a brief faultreport can be automatically generated according to various information of grid operation.

Description

technical field [0001] The invention relates to a grid meteorological information application system in the field of electric power system dispatching automation, in particular to a method for judging fault tripping of a line affected by a meteorological disaster. Background technique [0002] In the actual operation of the power grid, when the power grid line trips due to an accident, the power grid dispatcher hopes to locate the location of the fault as soon as possible, provide a preliminary analysis of the cause of the fault, and buy time for troubleshooting. [0003] In the conventional EMS system, only the remote signal displacement of the line switch of the EMS system, the accident trip information, or the protection action information in the credit information system are used to judge. There is a possibility of false alarms, and manual operations, line maintenance and other operations need to be excluded. Behavior. [0004] In the analysis of the cause of fault trip...
