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] Set up a memory real-time library in the platform layer of the power dispatching automation system, and expand the overall database environment of the system to be composed of the memory real-time library and the commercial library. 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 commercial library fault isolation method of the present invention is as figure 1 As shown in , the interface for acce...

Abstract

The invention discloses a commercial base fault isolation method applicable to a power dispatching automation system and achieves effective isolation of commercial base faults in the power dispatching automation system. A memory real-time base and special historical database service are arranged in a platform layer of the system, the memory real-time base is operated in a memory and is real-time mapping of a power grid model and static parameters in a commercial base, and a synchronization program is in charge of synchronization of content in the memory real-time base and the content in the commercial base. The historical data base service is in charge of all read-write operation relevant to the commercial base. The memory real-time base and the commercial base are packaged uniformly so as to guarantee that the outside of an access layer is transparent. Under the condition of commercial base faults, basic functions of the dispatching automation system are not affected, and monitoring can be conducted normally. After the commercial base returns to normal, historical data in a fault period can be smoothly recovered, and continuity and completeness of historical information are guaranteed.

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...
