Problems solved by technology

At present, the traditional methods for building power grid models in each dispatching center are independent modeling, external network equivalents, and multi-pole model splicing. In the actual operation of the new process, there are some problems such as untimely exchange of local models, mismatch between models and real-time data, and low efficiency of model merging. question

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as Figure 1-Figure 5 , a method for storing and traceable management of a multi-version power grid model, the method includes the following steps:

[0037] Step 1: Create model library tables in the distributed database and maintain model library table information;

[0038] Step 2: Import the initial model of the region and the initial model of the whole network into the distributed database;

[0039] Step 3: If the regional model is changed, generate a SQL incremental file, use the batch SQL statement interface provided by the distributed database to execute SQL operations, and store the new version of the regional model and the whole network model in the distributed database;

[0040] Step 4: Traceable management of multi-version grid models.

[0041] In the step 1, a model library table structure is created in the distributed database accor...

Abstract

The invention provides a storage and traceable management method for a multi-version power grid model. The storage and traceable management method comprises the following steps of: establishing a model base sheet in a distributed database and maintaining information of the model base sheet; leading a local initial model and an initial model of the whole network into the distributed database; if a certain local model is changed, generating a structured 1uery language (SQL) increment file, executing SQL operation in batches to store the new version local model and the whole network model into the distributed database; and traceably managing the multi-version power grid model. By the method, the multi-version power grid model can be effectively managed, and only increments are stored, and redundancy is not stored; and furthermore, due to data distributed storage, when the data amount of the model base sheet is increased, the query access speed can be obviously increased.

Description

technical field [0001] The invention belongs to the technical field of power system control, and in particular relates to a storage and traceable management method of a multi-version power grid model. Background technique [0002] The grid model reflects the connection status of the physical equipment of the grid, and the model needs to be modified accordingly when the physical equipment changes. In the production environment, offline modification is usually performed, and the legal model and its corresponding database, screen, index table, etc. are put into online operation after a series of verifications are completed. The production process will generate many versions of the model library. The traditional method is to export the model library table into a file and then name it according to time. However, this method is prone to confusing versions on the one hand, and has a large amount of data redundancy on the other hand. [0003] In addition, according to the requireme...
