1 Performance Evaluation of IEC 61850 Process

The paper presents the performance of a novel distributed bus differential protection scheme, which utilizes independent multi-principle advanced protection algorithms, including differential percent slope, delta phase directional comparison, rate of change of differential (ROCOD) currents, delta phase directional comparison on neutral current differential, and a check zone to secure the electr...

Real Time Simulation Testing Using IEC 61850

-As IEC 61850 becomes more widely accepted in the electrical engineering community, it is important that the testing tools keep pace with this development. IEC 61850 presents new challenges to real time simulation and closed-loop testing of protective relays. Electrical interfaces used for binary signaling and voltage/current amplifiers must be replaced by an Ethernet connection and an IEC 6185...

Synchrophasor Standards Development – IEEE C37.118 & IEC 61850

The concept of a phasor synchronized with the power system was introduced in the 1980s and standardized for the first time with the standard IEEE 1344. That measurement concept was further developed in the current synchrophasor standard, IEEE C37.118 that was completed in 2005. It is currently undergoing revision to fully define the measurement in all conditions including dynamic changes in the...

Switchgear Interlocking with IEC 61850-GOOSE

Understanding and Simulating the IEC 61850 Standard

The recent international standard IEC 61850 proposes a unified solution of the communication aspect of substation automation. However, the standard itself is not easily understood by users other than domain experts. We present our understanding of the IEC 61850 standard as well as the design and implementation of our simulation tool in this report. Also, we give suggestions on the implementatio...
