Problems solved by technology

The use of different analysis programs has brought a lot of complex and repetitive work to grid dispatchers in terms of data integration, data splicing, data conversion, and analysis and comparison of calculation results.
In the process of network computing, these tasks greatly reduce the work efficiency of dispatchers, prolong the calculation cycle, and are not conducive to timely response to power grid accidents

Embodiment Construction

[0072] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0073] The present invention proposes a unified data model scheme based on PSASP and PSD-BPA by comparing the differences between PSASP and PSD-BPA basic data models, and on this basis, develops a unified computing platform basic database that supports PSASP data and PSD -Storage and management of BPA data, supporting PSASP and PSD-BPA calculation applications. The unified data model research technology roadmap provided by the present invention is as follows: figure 1 shown.

[0074] Since the data models of the two power grid simulation software, PSASP and PSD-BPA, are very different, the core calculation program requires different parameters for the same type of components during calculation. The database needs to host different data models of the same type of components at the same time. In order to import data in...

Abstract

The invention relates to an interface method in the field of electric power system dispatching, in particular to a standard data exchange interface method of a parallel cooperative system. Data transmission between a database in the parallel cooperative system and an external data source is carried out through a data exchange interface; transmitted data adopt standard data formats; standard data adopt power grid data in E-language formats. The standard data exchange interface method comprises the following steps of (1) initializing an Oracle database; (2) reading a file in the E-language format to a memory; (3) copying in a list-to-list way; (4) writing the data to the Oracle database. According to the standard data exchange interface method disclosed by the invention, the problem of importing the data in different formats to the database is solved, and the defects such as manual data conversion and repeated operation which are caused by discrete of a daily traditional mainstream algorithm can be eliminated.

Description

technical field [0001] The invention relates to an interface method in the field of power system dispatching, in particular to a standard data exchange interface method for a parallel coordination system. Background technique [0002] At present, there are many types of system analysis programs used by dispatching organizations at all levels of power grid companies, including PSASP, PSD-BPA, and PSSE. The difference in the calculation results of the program has a great impact on the quality of power grid dispatching work and even the safe and stable operation of the power grid, and has hindered the advancement and implementation of the national networking work. The reason for the difference in the calculation results is the difference in the program itself, but the inconsistency of the original data model is the main factor leading to the difference in the calculation results, such as the difference in the load model and the difference in the generator control system. The u...
