A plug-and-play access configuration method for iec61850 smart devices

Abstract

The invention discloses an access configuration method for realizing plug-and-play of IEC61850 intelligent devices. The steps are: (1) a monitoring system periodically scans the system network where it is located, and when an intelligent device with a built-in ICD file is found to be connected to the system network, The monitoring system identifies the smart device and obtains its ICD file; (2) The monitoring system uses the ICD file of the smart device to automatically incrementally configure the original SCD file to obtain a new SCD file; (3) The monitoring system uses the new SCD file to generate Aim at the CID file of the smart device and transfer the CID file to the corresponding smart device; (4) The monitoring system and the smart device are re-initialized and a communication connection is established. The method realizes plug-and-play in the true sense, better solves the problem of difficult configuration and debugging of smart substation reconstruction and expansion, and can effectively improve the configuration and commissioning efficiency of smart substation reconstruction and expansion.

Description

technical field [0001] The invention relates to a method for realizing plug-and-play of IEC61850 intelligent devices. Background technique [0002] The smart substation communicates based on the IEC61850 protocol. At present, the way of accessing the monitoring system for smart devices is to first provide the ICD file describing the device capabilities to the monitoring system integrator, and the monitoring system integrator uses the system configuration tool to add it to the overall station system configuration description file After adding parameters such as communication configuration, send the SCD file to the smart device service personnel. Finally, the smart device service personnel use the device configuration tool to parse the SCD file and export the configured description file. configuration process. [0003] The above access method has many intermediate links, and relies too much on the participation of monitoring system integrators and intelligent device service p...

Problems solved by technology

However, this solution cannot solve the plug-and-play access to smart devices that do not exist in the SCD, and does not support the automatic incremental configuration of the SCD, and cannot be applied to the monitoring system based on the IEC61850 communication protocol of the SCD

[0005] Patent CN107231257A discloses a system and method for automatic configuration of process-level network equipment in intelligent substations, which mainly generates configuration files by analyzing the information obtained from SCD files and the obtained network topology information, and uses distributed subsystems to automatically configure the configuration files It is suitable for the initial commissioning stage of smart substations, but it cannot solve the plug-and-play connection of new smart devices for subsequent reconstruction and expansion, and does not support automatic incremental configuration of SCD
