Abstract

The invention provides a network-based data processing system for protecting control equipment, which is applied to a digital substation. The system aims at the digital substation, follows IEC61850 standard, receives, records, analyzes and manages the data of the substation; the equipment supports XML, so that the equipment configuration by various means and tools becomes possible and information is more convenient to exchange and share between different systems and different platforms; the system adopts a standard substation configuration language SCL for equipment configuration related to communication; configuration tools of any manufacturer meeting IEC61850 can identify the SCL; the novel data processing system for the digital substation has the advantages of digitalization, openness, easy maintenance and convenient expansion; and data analysis and processing software can conveniently analyze and process the data and manage the received data.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to a data processing system and method applied to network-based protection and control equipment of an IEC61850-based data sharing digital substation. Background technique [0002] Digital substation and related technologies are hot issues in the field of power system automation in recent years. It is the result of the development of computer technology, network technology, and power system requirements. IEC61850 standard, multifunctional IED (Intelligent Electronic Device) and communication network are the key research contents. [0003] The IEC 61850 standard (substation communication network and system standard) was formulated by the TC57 working group of the International Electrotechnical Commission on the basis of summarizing previous communication protocols to realize seamless communication between devices from different manufacturers. Its core cont...
