Embodiment Construction

[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] see figure 1 As shown, a differential synchronization method for power grid model data includes the following steps:

[0021] Step S101, analyze the grid model data of each data source system, generate a CIM XML file and save it in a temporary folder corresponding to the data source system (marked as: data_temp in this embodiment), and then enter step S102.

[0022] As a better embodiment, the process of analyzing the power grid model data of each data source system may specifically include the following steps: filtering out unidentifiable, redundant and erroneous data in the source system model data, and Convert the data whose format does not conform to the target data center to generate a CIM XML file consistent with the target data center schema. It should be noted that there may be one or more files gener...

Abstract

The invention provides a differential synchronization method and system for power grid model data. The method includes the steps of analyzing power grid model data of each data source system, generating a CIM XML (common information model extensible markup language) file and storing the file in a temporary file folder corresponding to the data source systems; subjecting files in the temporary file folder and files in a target data file folder to differential comparison to obtain differential data information including new data information, update data information and deleted data information; updating the corresponding power grid model data to a target data center according to the differential data information; clearing the files in a comparison target data file folder and cutting the files in the temporary file folder to the comparison target data file folder. Through the method and system, data synchronization efficiency is higher and data quality is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a differential synchronization method for grid model data and a differential synchronization system for grid model data. Background technique [0002] The power grid model is the basis for all kinds of informatization and automation systems of electric power enterprises to manage power grid related information. With the continuous development of power system informatization, the interaction of power grid model data between different systems is becoming more and more frequent, and more and more comprehensive data platforms based on data from multiple systems are being used. At the same time, XML (Extensible Markup Language, Extensible Markup Language) files based on CIM (common information model, public information model) have been widely used in data interaction operations, and most power grid systems support exporting grid model data to CIM-based XML document. [0003] At present,...
