“…An augmented method for voltage transformers calibration using synchrophasor measurement of ratio and bias errors is recommended [7]. The PMU calibrations are stipulated for enhancing the correctness of PMU measurements [8]. But due to less accuracy, it may be complicated to implement the PMUs across a wide area network.…”

Phasor Measuring Units (PMU) is considered as a feasible alternative for power system data communication and for the preparation of smart grid. To operate multiple PMUs in stable mode, synchronization is a much essential procedure. After examining the concise literature survey on topical PMU applications, this paper step ahead by considering prevailing objectives such as: extension of network topology and PMU calibration considering bias errors. The appropriate deployment of PMUs and intimidating situation influence the reliance on physical configuration. Hence, it is obligatory to extend the topology of the networks. Also, calibrating the PMUs in a definite trail is crucial as the phasor measurements will be corrupted by bias error. This paper proposes a novel framework for bias error detection and calibration of PMU while expanding the topology network. With a whale optimization algorithm based method to improve the accuracy of PMU measurements for enhancing power system state estimation, monitoring and control operations. Case studies on the standard test systems have been conducted to test the efficacy of the intended tool.

“…Seven unknowns appear in F and therefore the rank of H matrix has to be no less than seven which requires 3× ≥ 7 or ≥ 3, ( ∈ * ). Vector E is comprised of the difference between the true line impedance values and the calculated ones using (9)- (11). With the assumption that accurate line impedances are known, here are the steps for evaluating the bias errors in PMU measurements: -Step 1: calculate line impedance parameters R, X, and B according to (9) (19).…”

Abstract-Data quality of Phasor Measurement Unit (PMU) is receiving increasing attention as it has been identified as one of the limiting factors that affect many wide-area measurement system (WAMS) based applications. In general, existing PMU calibration methods include offline testing and model based approaches. However, in practice, the effectiveness of both is limited due to the very strong assumptions employed. This paper presents a novel framework for online bias error detection and calibration of PMU measurement using density-based spatial clustering of applications with noise (DBSCAN) based on much relaxed assumptions. With a new problem formulation, the proposed data mining based methodology is applicable across a wide spectrum of practical conditions and one side-product of it is more accurate transmission line parameters for EMS database and protective relay settings. Case studies demonstrate the effectiveness of the proposed approach.

With ongoing smart grid efforts, wide area monitoring and control requires advanced synchrophasor measurements based algorithms. However, testing and validation of these phasor measurement units (PMUs) are needed before integration into the physical grid. New procedures need to be developed for conformance testing of these devices. This work discusses an example testing tool PMU performance analyser (PPA) for conformance testing of PMU against standards. Number of related standards and other testing procedures have also been discussed. Example test results using PPA and associated test bed have been provided.
