Embodiment Construction

[0032] In order to be compatible with the information of equipment from different manufacturers and at the same time consider the development trend of the latest international standards, the substation information of the embedded system is connected to the real-time database software platform (CSM-RTDB for short) based on the "general structure of application data" described in IEC60870-5-3 ” as a blueprint, and established an abstract model for the storage of remote signaling, telemetry and electrical quantities. This abstract model also describes some other basic information of domestic substations, including protection events, alarm information, protection setting values ​​and disturbance records, etc. This model has absolutely nothing to do with external physical interfaces, transmission media, and communication protocols, and even has nothing to do with any equipment in the station. Generally speaking, this modeling process is completely "information object-oriented".

Abstract

The software platform of real time database includes abstract model of information based on objects of a variety of message bodies in transformer stations and function library of application programming interface (API) providing application software for periphery devices. Application management method of using embedded system possesses low requirement on interfaces of hardware and software, and high real time performance, reliability and availability, applicable to process of protection information in automation of transformer stations conveniently.

Description

technical field [0001] The invention relates to protection information processing technology in substation automation, in particular, to an application management method for substation information access real-time database software platform (CSM-RTDB) based on embedded system. Background technique [0002] The software platform design based on the embedded system is applied to the integrated control system in the substation automation system. By building a real-time database software platform that does not depend on any protection device communication protocol, it can be used not only as a protection device protocol conversion device for the substation monitoring system, but also as a protection device management device for substations of the power grid relay protection and fault information processing system in the substation. , in order to realize the collection, upload and remote transmission of protection device information of various relay protection equipment manufactu...
