Distribution network model incremental storage method based on E language

Abstract

The invention relates to a distribution network model incremental storage method based on the E language. According to the technical scheme, the method comprises a first step of receiving outer net models, conducting model transaction detection and transferring the models into an off-line bank, a second step of examining and approving model transaction, and a third step of conducting increment synchronization on the distribution network change models from the off-line bank to an on-line mode bank on the basis of the E language. The method is reasonable in design. According to efficient mechanisms, standardly achieving information sharing with external systems on the basis of the models and graphs up to the IEC 61970 standard, and achieving inside model analysis and model incremental storage on the basis of the E language, of the method, strategies of model detection, examination, approval and storage of feeder granularity are provided, transaction mechanisms of distribution network model equipment are completed, results of model transaction are effectively improved, and the friendliness degree of software and practicality of programs are promoted. The method is suitable for model data information access of power distribution automation systems, and provides data foundation for on-line monitoring and static and dynamic safety analysis of power distribution networks.

Description

technical field [0001] The invention belongs to the technical field of distribution automation, in particular to an E-language-based distribution network model incremental storage method. Background technique [0002] The distribution automation system needs to have a complete distribution network model management function. The distribution automation master station system model covers the main network and the distribution network. In addition to providing its own graphics and model integration tools, the system usually also has modeling tools for importing models from external systems, including importing high-voltage power grids from the superior dispatching system. Model, import medium voltage distribution network model from GIS system or PMS system, import low voltage equipment model from marketing system, etc. Following the IEC61970 / IEC61968 standard is the basic principle for sharing model information between distribution network systems and applications. The sharing ...

Problems solved by technology

[0005] At present, the distribution network model access function usually analyzes and updates the offline model library and the online model library as a whole, which leads to three major defects in the implementation: 1. Low efficiency, slow storage speed, slow difference analysis, online Slow investment; 2. The operation concurrency performance is poor, and different users cannot import data of different feeders at the same time; 3. It does not support partial model update based on feeder granularity, and the model changes in the offline library can only be put into the online library as a whole
