Abstract:


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 state estimation of dynamic phenomena. Effects of IEC 61850-9-2 communication network and the time errors due to the Asynchrony between Merging Units on the performance of the estimated Phasor are evaluated and presented in the paper.
