Abstract
Phasor Measurement Unit (PMU) communication delays and data frame losses play a critical role in designing of wide-area damping systems driven by synchrophasor technology. While there are a plethora of simulation-based studies addressing this issue, empirical results from actual PMUs deployed in the field are rare. This paper provides important insights into the characterization of PMU communication delays and data frame losses based on empirical results collected from a utility IP network. Additionally, efforts are also made to elicit design requirements considering the above PMU data quality problems. Furthermore, three distinct delay-robust wide-area damping control schemes parameterized according to the proposed requirements are validated against the empirical delays and data frame losses. Time-domain simulation results suggest that the control schemes in question can effectively stabilize the power system in all of the tested scenarios.
