Abstract

The invention relates to a method for realizing the remote configuration of a power distribution terminal by adopting a structured query language, belonging to the technical field of electric control. The method comprises the following steps of: replacing a configuration file as adopted by the traditional power distribution terminal with an embedded database of a database access language supporting the structured query language; realizing the transmission of an SQL (Structured Query Language) command by utilizing the communication format of an extensible markup language; and realizing the remote parameter configuration of the power distribution terminal by taking the embedded database as the configuration file and utilizing an XML (Extensible Markup Language) protocol as a carrier. A system for realizing the remote configuration of the power distribution terminal comprises an Ethernet data receiving and transmitting unit, an XML analyzing unit, an XML packing unit, an SQL language analyzing unit, an SQL executing unit and a database unit. The method and the system provided by the invention have the advantages of novel schematic design, clear process, stability, reliability, high extensibility, and capability of saving electricity and maintenance cost and can replace the traditional remote parameter setting system in the field of power distribution.

Description

Technical field: [0001] The invention belongs to the technical field of electric power automation control, and relates to a method for realizing remote configuration of power distribution terminals by using structured query language (SQL), which is suitable for remote parameter configuration of power distribution terminals in power transportation occasions, so as to automatically configure power consumption effect of the device. Background technique: [0002] The distribution automation terminal is a kind of electrical signal acquisition and switch control suitable for power distribution system 10KV and below column switch, ring main unit, switching station, power distribution room, transformer, etc., through communication with the main station SCADA system, It is a device to realize the measurement and control operation of power distribution automation. At present, the impact of power operation on the national economy occupies a dominant position, and the use and control o...
