Embodiment Construction

[0021] The "power system simulation" here refers to the reproduction of the essential process that occurs in the actual system through the power system model and computer software algorithms.

[0022] The following is a basic introduction to the database structure of the simulation center. By swapping in and out the data in these tables with disk files, the currently required data can be kept in the database, and temporarily unnecessary data can be exported to disk files, reducing data The current number of records in the table improves the access performance of the database. These tables are only a part of the database of the power system simulation center, and the structure of the tables is also a part required for calculation, which cannot really meet the actual needs. It is only used to understand the method of the present invention, and does not affect the realization of the present invention.

Abstract

The invention provides an electric system simulation centre data processing method based on file and database exchange, belonging to the electric system simulation centre data-processing and data-storing field. The data-processing and data-storing method realized in the invention adopts different job shift-in and shift-out strategies, thus the stored data in the current database can be obvious reduced and the access performance of the database can be greatly improved.

Description

technical field [0001] The invention belongs to the field of data processing and data storage of a power system simulation center, and in particular relates to a data processing method of a power system simulation center based on file and database exchange. Background technique [0002] Due to the complexity and uninterruptibility of the actual power system operation, it is not realistic to conduct experiments and research directly on the basis of it, so physical simulation or computer simulation must be used. The power system has been simulated by computer for decades. The early electric power scale was relatively small, and one person can independently complete the maintenance and simulation calculation of the power grid model on one machine. With the formation of cross-regional interconnected power grids and the continuous expansion of scale, the operating characteristics and dispatching control of power grids are becoming more and more complex, and the calculation amount...
