Problems solved by technology

[0003] In addition, after a fault occurs in the power grid, a fault analysis report is required. This report has always been filled in manually, and each department needs to report in a variety of formats. Manual filling greatly reduces work efficiency and is not standardized.

Embodiment 1

[0035] see figure 1 and figure 2 , the method for automatic generation of power grid fault location and analysis report based on multi-source data includes the following steps:

[0036] (1) Read real-time switch displacement information from EMS;

[0037] (2) Obtain the main equipment directly associated with the action switch through the network topology; the main equipment includes busbar, line, main transformer, high resistance and unit;

[0038] (3) Judging whether the master device has effective protection action information;

[0039] (4) Judging whether the action switch is overhauled;

[0040] (5) Judging whether the action switch is a fault trip;

[0041] (6) Carry out line fault identification in combination with EMS and credit information, and said line fault includes fault time, fault equipment, fault phase difference, fault loss load and reclosing action;

[0042] (7) For line faults, combined with the fault distance given by traveling wave ranging and the lo...

Abstract

The invention discloses a multi-source data based grid fault positioning and analysis report automatic generating method, which is characterized in that fault recognition and fault accurate positioning are performed by comprehensively utilizing EMS (Energy Management System) information, relay protection and fault information and travelling wave distance measuring information, visualized display and alarming can be performed on a grid fault, and the grid operation and maintenance personnel are notified timely through a short message alarm platform. Meanwhile, a detailed grid fault tripping analysis report is automatically generated by comprehensively utilizing a line lean system, a lightning monitoring system, an icing monitoring system, a multispectral mountain fire monitoring system, a typhoon monitoring system and the like. According to the invention, a grid fault can be positioned quickly and accurately, and fault information is automatically sent to the grid maintenance personnel through the short message platform, thereby saving the time for quick recovery of the grid fault, and improving the work efficiency of the grid maintenance personnel. The multi-source data based grid fault positioning and analysis report automatic generating method provided by the invention avoids time delay brought about by manual filling and reporting, and saves the labor cost.

Description

technical field [0001] The invention relates to the technical field of power grid operation and maintenance, in particular to a method for automatically generating power grid fault location and analysis reports based on multi-source data. Background technique [0002] In summer, as the temperature rises, the load demand is large. In order to ensure the electricity demand of users, the power grid operation management department has to increase the output of units as much as possible, increase the transmission capacity of the line, and increase the risk of power grid operation; , Rainfall, strong wind, winter icing and other natural disasters occur frequently, resulting in power grid equipment failures, especially line failures. Therefore, timely detection of grid faults and rapid and accurate location of faults are of great significance for assisting grid operation and maintenance personnel to solve faults in a timely manner and quickly restore power supply. [0003] In addi...
