Abstract
The features of configuring software and hardware of modern data acquisition systems as part of a digital substation to comply with the international standard IEC 61850 are considered. Given recommendations for energy efficient software and hardware configuration for 110 kV, 6-35 kV and 0.4 kV power consumption level which allow you to increase the reliability of the system by 1.5-2 times.
Highlights
A modern electrical substation is designed for distribution and conversion of electric power and combines both standard electrical devices of relay protection and power metering, as well as electrical automation and control devices
In this paper we have considered the features of control and data acquisition systems according to the IEC 61850 standard
Application of GOOSE protocol in combination with correct design and parameterization of information network and relay protection devices allows to refuse from using copper circuits for signals transfer, providing the required level of reliability and performance
Summary
A modern electrical substation is designed for distribution and conversion of electric power and combines both standard electrical devices of relay protection and power metering, as well as electrical automation and control devices. As the number of consumers and the number of recorded parameters is constantly growing, the number of simultaneously transmitted signals and data transmission channels is increasing. All this data needs continuous processing and analysis in modern ERP and SCADA systems. To program and operate such automation systems it is necessary to use clear standards and data transfer technologies. At the software level, such standards include the IEC 61850 standard [2,11], which describes the data transfer model
