A method for sharing historical status data of power grid

Abstract

The invention provides a power grid history state data sharing method. The method includes that a model exporting module acquires a model from a power automatization system to form an E language model file; a data exporting module acquires history state data corresponding to the model file from the power automatization system and converts the history state data to be of a history state data structure to form a history state data file; a power grid model base and a history state database respectively acquire and store the model file and the history state data file; a model importing module reads and analyzes the model file and imports the model file into a target power automatization system; a data importing module reads and analyzes the history state data file and imports the history state data file into the target power automatization system. By the method, the history state data closely related to a specific power grid model file are taken as an independent text file to be stored and issued, correlation characteristics, of the history state data, with corresponding models are retained, and sharing of power grid history state data is realized.

Description

technical field [0001] The invention relates to a method in the field of electric power system and automation thereof, in particular to a method for sharing historical state data of a power grid. Background technique [0002] The power grid model is the basis for the application of various power automation systems. In order to standardize and efficiently save and publish the power grid model, various researches have been carried out at home and abroad. "Q_GDW215-2008_ Power System Data Markup Language - E Language Specification", "Q / GDW_216-2008 Power Grid Operation Data Exchange Specification", "CIM / E Power Grid Physical Model Description and Exchange Specification (Trial)" and other standards and specifications. The above specifications have laid the foundation for sharing and exchanging models between various power automation systems, especially between dispatching automation master station systems at all levels. [0003] However, the sharing and exchanging of historica...

AI Technical Summary

Problems solved by technology

[0004] 1) The historical state data of the power grid is closely related to a specific model, and the historical state data is meaningless without the corresponding model; the historical state data of the power grid must be closely related to a specific power grid model, and both parties to the exchange of historical state data must understand each other’s power grid model

[0005] 2) The historical state data is massive, which is manifested in the fact that there are many sampling points, the sampling period is different, and the sampling volume is large

[0006] 3) Various types of power automation systems save historical state data in various ways, and there is no unified method

[0008] The above problems have resulted in low efficiency in the exchange and sharing of historical state data between power automation systems. The information itself cannot be self-explanatory and must be accompanied by a lot of other information. The information redundancy is high; the solution is relatively specific, and it is difficult to adapt to various Model and data storage requirements specific to an automated system
