Abstract

The invention relates to a broadband measurement data association relationship analysis method and system. The method comprises the steps: S1, a broadband measurement processing unit subscribing to multiple spaced broadband measurement data of multiple broadband measurement devices concurrently in real time; S2, calling an alarm action event report file and an event recording data file corresponding to the broadband measurement data; S3, analyzing the alarm action event report, and extracting alarm information; and S4, constructing a ternary association relationship among the alarm information, the event recording data and the synchronous phasor broadband historical data, establishing a broadband measurement data index, and providing multi-dimensional broadband measurement data associationquery. According to the invention, multidimensional query of broadband measurement data of a processing unit can be realized, associated query of a large amount of broadband measurement data can be carried out, and further analysis and application of the broadband measurement data are supported.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to a method and system for analyzing association relationship of broadband measurement data. Background technique [0002] With the construction and development of smart grids, power electronic equipment related to new energy, DC transmission, and AC flexible transmission are widely used in all aspects of the grid, and the non-power frequency electrical equipment such as harmonics, interharmonics, and subsynchronous oscillations brought by them The amount is also increasing day by day, endangering the safe and stable operation of the power grid. Traditional measuring devices have weak response ability to non-power frequency electrical quantities, and the measurement accuracy decreases when the waveform is distorted, which has been difficult to meet the needs of modern power grid operation monitoring. At present, the research and application of broadband m...
