Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and tables. The implementation of the method of the present invention includes five parts to realize fast and static database building of the communication device.

[0024]The first part is the formation of "basic classification rules". In the IEC61850 model, each data object (DO) is composed of multiple data attributes (DA), and the data attributes belong to different functional constraints (FC). Data objects are defined by corresponding Common Data Classes (CDC). Use the three options of FC, CDC, and DA to determine the specific application of a measuring point. For convenience, use the method of character strings to combine these three items. The format is: "FC$CDC Name$SDO ID Name[$SDO ID Name[$…]]$DataAttributeName”, where the SDO ID Name part can be nested, for example: “MX$WYE$phsA$cVal$mag$f”.

Abstract

The invention relates to a configuration method for a database of a communication device in a digital substation. The configuration method comprises the following steps: forming an independent middle text, namely, a rule file, according to an IEC61850 standard and a mapping rule for the database of the communication device; automatically generating data of a measuring point according to an engineering requirement and inputting the data of the measuring point into the database of the communication device, for an imported ICD (Interface Control Document) of the device during the configuration process of the communication device; and configuring through configuration software. According to the configuration method, the middle text is supplied to the database of the communication device and the database of the communication device is statically generated according to the corresponding rule in the middle text after the configuration software is imported into the ICD of an IEC61850 device, wherein the rule in the middle text comprises three parts: a basic classifying rule, a prior rule and a shielding rule. According to the configuration method, the database for the measuring point can be flexibly and automatically generated for the imported ICD of the device according to the engineering requirement, so that the process of manually selecting the point by an engineering configuring person is omitted, the possibility of configuration fault is eliminated and the efficiency of engineering configuration is increased.

Description

technical field [0001] The invention relates to the field of power system automation, in particular to the IEC61850 device model mapping and communication device database building method in a digital substation. Background technique [0002] At present, the main function of the communication device operated by the power system plant (power plant, substation) is to forward the information of the secondary equipment in the plant to the remote main station, and the function is positioned as the gateway in the station. The communication protocols used by the communication device and the remote master station are commonly used, such as IEC 101 / 104 / 103. Currently, these standards organize data in the form of a list, and the data classification is relatively clear. For example, the information exchanged with the dispatching master station is determined as six remote data. (Remote signaling, telemetry, remote control, remote adjustment, remote pulse, gear position). For the substat...
