Access configuration method for realizing plug-and-play of an IEC61850 intelligent device

Abstract

The invention discloses an access configuration method for realizing plug-and-play of an IEC61850 intelligent device, which comprises the following steps that: (1) a monitoring system periodically scans a system network where the monitoring system is located, and when the intelligent device with a built-in ICD file is accessed to the system network, the monitoring system identifies the intelligentdevice and obtains the ICD file of the intelligent device; (2) the monitoring system performs automatic incremental configuration on the original SCD file by using the ICD file of the intelligent device to obtain a new SCD file; (3) the monitoring system uses the new SCD file to generate a CID file for the intelligent device and transmits the CID file to the corresponding intelligent device; and(4) the monitoring system and the intelligent device are reinitialized and establishes a communication connection. According to the method, plug-and-play in the true sense is achieved, the problem that the intelligent substation is difficult to reconstruct, expand, configure and debug is well solved, and the reconstruct, expand, configure and debug efficiency of the intelligent substation can be effectively improved.

Description

technical field [0001] The invention relates to a method for realizing plug and play of IEC61850 intelligent devices. Background technique [0002] Smart substations are based on IEC61850 protocol communication. At present, the way to connect smart devices to the monitoring system is to first provide the ICD file describing the capabilities of the device to the monitoring system integrator, and the monitoring system integrator uses the system configuration tool to add it to the system configuration description file of the whole station. In the SCD, after adding communication configuration and other parameters, send the SCD file to the smart device service personnel, and finally the smart device service personnel use the device configuration tool to analyze the SCD file and export the configured description file CID to the smart device through FTP or other methods and then restart to complete configuration process. [0003] The above-mentioned access methods have many interm...

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
