Embodiment Construction

[0035] In order to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0036] After the line fault trips and directly transmits power without processing, it is the line strong power transmission. The probability of transient faults on transmission lines is relatively high, and strong power transmission can quickly restore the power supply of faulty lines, protect the grid structure from damage, and improve the transient stability of the grid. Therefore, after the line fault trips, the on-duty dispatcher should comprehensively consider the fault information and the location of the fault point to determine whether to send it by force.

[0037] At present, the power grid dispatching regulations of each grid province have detailed regulations on the forced transmission conditions of the line. For example, the "Shandong Power Grid Dispatching Control Management Regu...

Abstract

The present invention provides an intelligent processing method for a transmission line fault and an apparatus thereof. The method comprises: 1) according to information sent by an EMS system, determining whether to start an analysis program; 2) calling data of the EMS system, a fault recording and ranging system and a line parameter library; 3) comparing the information called in step 2) with data in a determining rule library, and determining whether to perform forced energization, and performing step 4) if yes, and proceeding to step 5) if no; 4) determining a force energization terminal by means of the information in the line parameter library; and 5) outputting a result. The apparatus comprises the EMS system, the fault recording and ranging system, an intelligent system main station, a line database, the determining rule library and a client. By using the apparatus, intelligent processing of transmission line faults can be realized.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an intelligent processing method and device for transmission line faults. Background technique [0002] After the failure of the transmission line, when the conditions for forced transmission are met, the dispatcher should immediately order a forced transmission. For transient faults, forced transmission can restore faulty lines to operation, effectively improving the steady-state and transient stability of the power grid. Traditional processing methods rely on manual experience analysis, long judgment time, high labor intensity, low work efficiency, and cannot meet the requirements of fast and accurate processing of power grid faults. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention proposes a transmission line fault intelligent processing method and its device, which can realize the intelligent process...
