Problems solved by technology

[0004] There is no unified understanding of the overall structure of digital substations and the structure and functions of smart devices, especially in terms of process bus. The information sharing of the whole station realizes the functions of the substation system, which greatly restricts the development of digital substation technology

Abstract

The invention provides a centralized digital transformer substation system. By adopting various new technologies and new devices, a new level centralized multifunctional intelligent device and a system are realized, thereby laying the foundation for the construction of a digital electric network. Based on an IEC 61850 standard, high speed Ethernet exchange and a virtual local area network (VLAN) technology, the system constructs a digital transformer substation information model and a communication network, and realizes sharing of information of the whole substation. On the basis, function integration of a digital transformer substation is realized and a system structure is simplified. A bay level multifunctional intelligent electronic device, i.e. a system controller integrates the functions of protection, measurement and control, wave recording and the like into a whole, and greatly simplifies the bay level device and wire connection; a process level intelligent terminal integrates the functions of a merging unit and an intelligent operation box into a whole; and all devices of each level provide models and interfaces conforming to the IEC 61850 standard.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and particularly relates to digital substations and related technologies, such as the IEC 61850 standard, intelligent electronic equipment, network communication technology, etc., and provides a system based on total station information sharing by adopting various new technologies and new equipment. Centralized digital substation system. Background technique [0002] The traditional substation automation technology based on microcomputer protection and computer monitoring has gradually matured and improved after more than ten years of development, and has played a very important role in improving the automation level of the power grid and the reliability of power transmission and distribution. However, due to some defects in traditional substation automation technology, such as various automation devices and subsystems in the substation are independent, and there are many communica...
