Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] When applying the commercial library fault isolation method proposed by the present invention, it is necessary for the scheduling automation system to support the mixed environment of the commercial library and the real-time memory library.

[0016] A memory real-time library is set in the platform layer of the power dispatch automation system, and the overall database environment of the system is expanded to consist of a memory real-time library and a commercial library. The memory real-time library consists of the grid model in the commercial library and the static parameters in memory The real-time image is composed, and the synchronization program is responsible for the synchronization of the content in the memory real-time library and the content in the commercial library. A typical database environment for implementing the commerc...

Abstract

The invention discloses a commercial library fault isolation method suitable for an electric power dispatching automation system, so as to realize effective isolation of commercial library faults in the electric power dispatching automation system. The present invention sets a memory real-time library and a special historical database service in the platform layer of the system. The memory real-time library runs in the memory and is the real-time image of the power grid model and static parameters in the commercial library, and the synchronization program is responsible for the memory real-time library Synchronization of the content in the database and the content in the commercial library; the historical database service is responsible for all read and write operations related to the commercial library. The memory real-time library and the commercial library are uniformly packaged to ensure that the access layer is transparent to the outside world. The invention realizes that the basic functions of the scheduling automation system are not affected in the case of a failure of the commercial library, so that the monitoring can be carried out normally, and after the commercial library returns to normal, the historical data during the failure period can be restored smoothly, ensuring the continuity of historical information sex and integrity.

Description

technical field [0001] The invention relates to a method for fault isolation of a commercial library, and belongs to the technical field of power system scheduling automation. Background technique [0002] Early electric power dispatching automation systems did not use commercial databases (commercial databases are relational databases), and their historical data were stored in a private file format for management. The main problem with this data management method is that information retrieval is difficult. In addition, Because there is no open interface, it is difficult to carry out the work of information reuse. With the maturity of commercial database technology and the development of scheduling automation systems, domestic scheduling automation systems have begun to use commercial databases, and the data storage and retrieval capabilities have been greatly improved. However, one more link means one more point of failure. Sometimes it malfunctions and does not work prope...
