Phasor measurement units (PMUs) provide the basis for synchrophasor measurements, which are good data sources for capturing power system dynamic behavior. The recently published IEEE Standard C37.118.1-2011 characterizes the dynamic performance of synchrophasor measurements with two performance class filters: P-class and M-class. Practical implementation of a PMU to meet all dynamic requirements is...
This paper investigates the bad data detection issues in power system state estimation considering SCADA and PMU measurements. The traditional State Estimator (SE) containing only SCADA measurements, two One Phase SEs and one Two Phase SE are evaluated. The SEs are assessed by considering measurements containing gross and gaussian errors and two classical methods for measurement standard deviations...
The paper introduces a simple, fast and computationally efficient phasor estimation algorithm under dynamic conditions using convolution analysis. The performance of convolution based phasor estimator is effectively tested under different dynamic/noisy conditions as per IEEE C37.118.1-2011 standards. The results revealed that the proposed algorithm estimates the dynamic phasor accurately irrespective...
