Embodiment Construction

[0031] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0032] refer to figure 1 As shown, the power grid accident opening auxiliary analysis method of the present invention is characterized in that it comprises the following steps:

[0033] Step 1: Collect the original data of accident opening from multiple data sources, and build an accident opening database. The data sources include EMS database, PMS database and prefecture-city fault reporting database;

[0034] Step 2: Preprocessing the original data of accident opening in the accident opening database to obtain the accident opening data;

[0035] Step 3: Integrate and display the accident opening data with equipment as the center.

[0036] After the original data of accident tripping goes through the above three steps in sequence, the maturity and usability of the data are strengthened layer by layer. In order to solve the shortage of...

Abstract

The invention discloses a power grid accident opening auxiliary analysis method. The power grid accident opening auxiliary analysis method is characterized by comprising the following steps that step 1 accident opening original data are collected from multiple data sources, an accident opening database is built, and the data sources comprise an EMS database, a PMS database and a city fault reporting database; step 2 the accident opening original data in the accident opening database are pre-processed, and accident opening data are obtained; step 3 the accident opening data are displayed in an integrated mode with equipment as the center. By means of the power grid accident opening auxiliary analysis method, a complete power grid accident opening auxiliary analysis system is built, the power grid equipment with trip faults can be rapidly positioned, and the result is accurately judged according to the auxiliary information.

Description

technical field [0001] The invention relates to an auxiliary analysis method for power grid accident opening, in particular to an auxiliary analysis method for power grid accident opening with multiple data sources. The invention belongs to the field of power grid fault analysis of power systems. Background technique [0002] Power grid accident opening refers to the abnormal tripping of circuit breakers and other equipment during the operation of the power grid. It will not only endanger the production and operation of the power grid, but also may affect the normal power consumption order of the society. Quickly and accurately obtaining power grid accident opening information is an important supporting means to timely understand the operation status of power grid equipment, deeply grasp the level of equipment operation and maintenance, and comprehensively improve the reliability of power supply. [0003] At present, the analysis steps of power grid accident tripping are gen...
