Power grid fault analysis device and method based on SCADA system

Abstract

The invention discloses a power grid fault analysis device and method based on an SCADA system. The analysis device comprises a data layer module, an analysis layer module, and a presentation layer module, wherein the data layer module is used for generating a real-time database and a historical database based on the SCADA system; the analysis layer module is used for receiving data of the data layer module for analysis to generate a fault information analysis result; the presentation layer module is used for receiving the fault information analysis result of the analysis layer module for carrying out data graphical presentation; and the data layer module is in communication connection with the analysis layer module, and the analysis layer module is in communication connection with the presentation layer module. According to the power grid fault analysis device, the problem that alarm source modes are numerous, and information is omitted when being uniformly reported to a real-time alarm window is solved; meanwhile, the problem that a real-time alarm window is single in alarm information display form, and the fault discrimination is insensitive is solved; and finally, the problem that a potential relation exists between important section indexes of a power grid and fault equipment when a fault occurs is solved.

Description

technical field [0001] The invention relates to a power grid fault analysis device and method based on a SCADA system, and belongs to the technical field of power system alarm analysis. Background technique [0002] With the construction of ultra-high voltage and energy Internet systems, the operation characteristics of the power grid have undergone profound changes, and the operation of the power grid has become more complex. The stable operation of the power grid is the first element for the operation of a strong and smart grid. Once the power grid fails, the huge amount of data will cause great trouble for the analysis of the regulators. [0003] Such as figure 1 As shown, the traditional power system fault analysis system uses the alarm as the main carrier, that is, the online operation and detection module in the SCADA system analyzes and detects the current, limit and other indicators in the power system in real time. The alarm module reports the fault details to the...
