Evaluation of IEC 61850-9-2 samples loss on total vector error of an estimated phasor

This paper evaluates the performance of proposed phasor estimator at different operating conditions within IEC 61850. The estimator relies on the Unsented Kalman Filter which is employed for computing the Phasor based on IEC 61850-9-2 Sampled Measured Values casted by the substation merging units. The criterion for evaluating the estimated Phasor is the Total Vector Error as define in IEEE C37.118 standard. The Total Vector Error is analyzed for the effects of the IEC 61850-9-2 samples loss, operating conditions at different Nodes Number and IEC 61850-9-2 frame size.
