Synchronized Phasor Measurements in a Dual Layer Hybrid State Estimator
Original scientific paper The architecture of the proposed Dual Layer Hybrid State Estimator starts with the linear state estimator that only takes synchrophasors as inputs and calculates states of the buses with the deployed Phasor Measurement Units (PMUs) and their adjacent buses. These states are used to obtain the pseudomeasurements that are processed together with conventional SCADA measur...
متن کاملSynchrophasor Assisted Prediction of Stability/Instability of a Power System
This paper presents a technique for real-time predictionof stability/instability of a power system based on synchrophasor measurements obtained from phasor measurement units (PMUs) at generator buses.For stability assessment the technique makes use of system severity indices developed usingbus voltage magnitudeobtained from PMUs and generator electrical power. Generator power is computed using ...
متن کاملModel Validation Using Synchrophasor Data - - A Synchrophasor Success Story
Mathematical models – from models of individual transmission elements and power plant components to production cost models and system models -are used for every aspect of power system planning and operations. When a generator or system does not act in the way that its models predict, the mismatch between reality and the model-based expectations can lead to severe disturbances and costly equipme...
متن کاملA Hybrid Estimator for Selectivity Estimation
Traditional sampling-based estimators infer the actual selectivity of a query based purely on runtime information gathering, excluding the previously collected information, which underutilizes the information available. Table-based and parametric estimators extrapolate the actual selectivity of a query based only on the previously collected information, ignoring on-line information, which resul...
متن کاملExtracting Steady State Components from Synchrophasor Data Using Kalman Filters
Abstract: Data from phasor measurement units (PMUs) may be exploited to provide steady state information to the applications which require it. As PMU measurements may contain errors and missing data, the paper presents the application of a Kalman Filter technique for real-time data processing. PMU data captures the power system’s response at different time-scales, which are generated by differe...
