Self-discovery and self-configuration method and device of universal substation IED based on UPnP

Abstract

According to the UPnP-based universal substation IED self-discovery and self-configuration method and device, aiming at the problems of low access and manual configuration efficiency, large workload and the like of a large number of IEDs in an existing intelligent substation, a UPnP protocol is adopted, so that the universal IED can be identified in a network, and automatic discovery of the IED isrealized through a substation UPnP network; automatic configuration of the equipment is realized through UPnP control; through self-discovery of the equipment, the equipment can be quickly discoveredand identified and is automatically configured, remote configuration of the equipment is realized, controllability of the equipment can be efficiently realized, and reliability and consistency are ensured while efficiency is improved.

Description

technical field [0001] The invention relates to an IED access configuration of an intelligent substation, in particular to a method and device for self-discovery and self-configuration of a general substation IED based on UPnP. Background technique [0002] Smart substation is an important part of the smart grid. There are many types of equipment involved in the field of smart substations, including smart terminals, protection devices, measurement and control devices, and telecontrol terminals. Due to the different types of devices, the functions of different devices are very different; the communication methods of devices of different device manufacturers are not uniform. Moreover, there are a large number of intelligent electronic devices (IEDs) in smart substations. When IEDs are connected to the substation network, a large amount of human resources are required for device access and manual configuration, and the accuracy and consistency of information are not guaranteed....

AI Technical Summary

Problems solved by technology

[0005] Therefore, the following problems exist in the transformation process of substations from traditional substations to smart substations: 1. The equipment communication in the substation has changed from traditional cable communication to network communication. The identification and approval of a large number of IEDs in the network still need manual confirmation. Confirm that the access efficiency of IEDs in the network is low; 2. Now the IED functions tend to be integrated and generalized, but the relative position and function of the IED in the substation system is relatively fixed, and its function configuration needs to follow the engineering configuration process of IEC 61850, from The corresponding IED instance configuration file (CID) is generated in the station-wide configuration file (SCD). Although the CID file can be automatically generated from the SCD file by software tools, the generated CID file also needs to be manually imported into the IED. For the function configuration of the IED, The workload of manual configuration and import is relatively large; 3. In the process of transforming traditional substations into smart substations, because traditional substations may adopt various industrial control protocols in various links, while smart substations have formulated a unified protocol under the IEC 61850 standard There is a problem that the new and old protocols are different for the IED
