Abstract

The platform is designed based on optical fiber communication technique, and in conformity to IEC61850 standard ¿C unique international standard about communication network and system of transformer substation. The platform is composed of main control module, optical fiber hub module, analog input module, switching value I / O module, and man - machine interface module. Through own redundant optical fiber interface, the main control module, analog input module and switching value I / O module are connected to two sets of optical fiber hub module so as to constitute redundant optical fiber communication network, and realize distribution type protection and coordination control. Through RS-485 communication interface, man - machine interface module is connected to the main control module and exchanging interactive data, providing local display and operation interface. Through optical fiber interface, the main control module is connected to external devices in transformer substation layer.

Description

technical field

[0001] The invention follows the IEC61850 standard, the only international standard for substation communication networks and systems, and is a new type of fully networked digital protection platform designed based on optical fiber communication technology, belonging to the technical field of power system relay protection. Background technique

[0002] Since the emergence of substation automation technology in the early 1980s, a considerable number of substation automation systems of various voltage levels have been invested at home and abroad. The substation automation system is used to integrate the originally separated control, protection, monitoring, communication and measurement devices in a suitable form. The automation system is composed of a small number of multifunctional intelligent electronic devices (IED, Intelligent Electronic Device), and the information is realized through the substation communication network. Sharing not only reduces the use o...
