Performance Evaluation of Phasor Estimator within IEC 61850-9-2 Communication Network

This paper presents performance evaluation of a new architecture for phasor estimation within IEC 61850 substation Process-Bus. To benefit from the raw IEC 61850-9-2 Sampled Measured Values streamed with high sampling rate from various Merging Units at substation bay level, Unsented Kalman Filter is proposed to be utilized in the computation of Phasor at substation process level to enhance the ...

T Implementation Issues with IEC 61850 Based Substation Automation Systems

International Electro-technical Commission (IEC) has developed a new global standard, IEC 61850 for communication systems in power substations. This standard provides interoperability among the all communication devices within the substation. This paper presents basic features of communication systems proposed by IEC 61850, such as functional hierarchy, OSI-7 layer based communication, and proc...
