A data construction method and system suitable for power grid dispatch calculation

Abstract

The invention provides a data construction method and system suitable for power network dispatching calculation. By use of the method, data for power network dispatching calculation is constructed through establishing a calculating data project, importing provincial dispatching data, and splicing dispatching data. The system comprises a project management module, a data management module, a data verification module, and a calculation analysis module. By use of the method and system, power network dispatching calculation with provincial dispatching data and local dispatching data is realized, wherein the provincial dispatching data and local dispatching data can be managed uniformly, maintained separately, and spliced for use as required; the system is flexible and effective; data source end maintenance and global sharing are realized; mutual influence of data modification is effectively prevented to help data analysis and verification of each area; By use of the method and system, calculating data can be flexibly constructed as calculation required, the uniqueness and accuracy of power network dispatching are guaranteed.

Description

technical field [0001] The invention relates to the field of power system security, in particular to a data construction method and system suitable for power grid dispatch calculation. Background technique [0002] The power grid calculation data of the dispatch center can be divided into online data, offline data, etc. according to the application type. The power grid dispatching operation mode department usually has the offline operation mode data of the power grid, which is generally expressed as several typical mode data up to a certain planning time point. Offline data is characterized by a relatively complete typical power grid structure, models and parameters of power grid equipment, and typical or bad operating modes of the system, which is suitable for detailed and in-depth analysis of the physical characteristics of the power grid. Mode operators use these off-line mode data to perform extensive normal mode and maintenance mode checks to determine section limits w...

Problems solved by technology

[0004] Multi-level scheduling and coordination are required to form network-wide data, which is inefficient and easy to repeat work

Data modification is carried out independently at all levels of scheduling, and the review, integration, uploading, and distribution of scheduling data at all levels require manual coordination. The data formation cycle is long, and it is difficult to check for errors in the data. Some errors in the data may cause maintenance and correction. It will be relatively lagging behind, and it is easy to lead to inconsistent data model versions of scheduling at all levels; once the infrastructure project is put into production, there are changes or multiple ground survey data are incorrect, it will lead to repeated work and prolong the data formation cycle

[0005] The offline data of the whole network generally only maintains a few typical data, and the data uses are limited
