Embodiment Construction

[0018] A method for event-based monitoring and modeling of main and auxiliary equipment in a power system described in this embodiment is characterized in that it includes the following steps:

[0019] (1) For the devices produced by different manufacturers, the names of the signals reflecting the same event are different, and the text form is not conducive to the automatic judgment of the program. It is necessary to extract the features of the monitoring signal:

[0020] Obtain monitoring signals, decompose each monitoring signal into plant type, voltage level, and auxiliary equipment type characteristic attributes according to its representative power grid, equipment characteristics and logical results, and analyze the corresponding relationship between historical alarm information and practice. The specific description becomes structured and classifiable information, which is convenient for subsequent logical processing.

[0021] (2) For discrete event modeling, it is neces...

Abstract

The invention discloses an event monitoring modeling method for main and auxiliary equipment of a power system, which comprises the following steps of: (1) collecting monitoring signals, and decomposing each monitoring signal according to characteristic attributes; (2) refining each type of characteristic attributes, and carrying out classification modeling; (3) arranging the models after classification modeling, combining and splicing to form intermediate models, and screening the intermediate models according to a preset rule to obtain a monitoring information model; and (4) carrying out attribute solidification on the monitoring information model, so that the monitoring signal is completely matched with the monitoring information model. According to the invention, objectified modeling for power grid and equipment is realized for monitoring information on a platform layer, mapping from main and auxiliary equipment monitoring signals to a signal dictionary is realized, a main and auxiliary equipment integrated event monitoring information model is established, the working pressure of monitoring personnel is greatly reduced, and the monitoring effect is improved.

Description

technical field [0001] The invention relates to a modeling technology of power system equipment, in particular to an event-based monitoring modeling method for main and auxiliary equipment of a power system. Background technique [0002] The State Grid Corporation of China coordinates power grid dispatching and equipment operation resources, incorporates the operation information of substation equipment into the control platform for unified management, realizes the integrated monitoring of power grid load, power flow and equipment operation, and improves resource management capabilities and power grid operation efficiency. With the increasing frequency of multi-station monitoring, multi-station and multi-equipment operation, simultaneous accidents and abnormalities of multiple equipment, the impact on monitoring work and power grid security has become increasingly prominent. Monitoring personnel bring huge information monitoring pressure, especially when power grids and equi...
