Steadily improving performance of inertiai sensors necessitates significant enhancement of the methods and equipment used for their evaluation. As the nonlinearity of sensors decreases and gets close to that of' the exciters, new challenges arise. One of them, addressed in this research, is a superposition of errors caused by the nonlinearity of tested devices with noniinear distortions of excitation empioyedfor expérimentai evaluation. This can iead to a cancellation, at least partial, of the effects of both imperfections and underestimation of the actual distortions of the evaiuated sensors. We impiement and analyze several system architectures and evaluate components of applicable motion generation systems from the viewpoint of satisfying the relevant, often conflicting requirements posed by the evaluation of high performance inertiai sensors. Robust mechanical integration of the guidance, actuation, and measurement functions emerges as a key factor for achieving the needed quality of generated test patterns. We find precision air bearing stages, such as ABL1500 series (Aerotech) most suitable for implementing the needed experimental setup. We propose an architecture with two reciprocating stages, implement and evaluate its core components, and illustrate its performance with experimental results.

“…It is derived under the assumption that the input voltage is a pure sine wave. In this paper, in which a problem of power measurement is addressed, the distortion of input signals should be taken into account in the way as described in (2). The NTA algorithm belongs to the family of nonrecursive nonlinear estimators.…”

“…This creates the need for a more accurate method of measuring the power components in the presence of signal distortions. In [2], it is recommended to replace the existing solid-state energy meters with digital meters. The functionality of digital meters is determined by the quality of the input signals, the quality of the digital components, and the selection of the numerical algorithm for input signal processing.…”

Abstract-In this paper, a new two-stage Newton-Type Algorithm for the measurement of power components according to the IEEE Standard 1459-2000 is presented. To estimate their spectra and fundamental frequency, in the first stage, the current and voltage signals are processed, whereas in the second stage, the power components are calculated based on the results obtained in the first stage. The algorithm considers the frequency as an unknown parameter and simultaneously estimates it with the input signal spectrum. Through this, the algorithm becomes insensitive to frequency changes and the problem becomes non-linear. The algorithm performance is tested using computer-simulated and laboratory tests.

“…However, the switching feature of power converters, together with the intermittent and stochastic behaviors of renewable energy sources, challenge the power quality (PQ) of modern power systems [1][2][3][4][5][6]. Typical PQ issues, such as voltage sags/swells, reactive currents, voltage/current harmonics, and voltage/current imbalances, may cause undesirable power losses, equipment malfunction, and even blackouts [7][8][9][10]. As such, grid codes, e.g., IEEE Standard 519-2014 [11], set clear requirements on current and voltage qualities of grid-tied power converters.…”

Distributed static compensators (DSTATCOMs) are grid-connected power electronic equipment dedicated to compensating reactive power as well as improving voltage regulation in distribution networks. They eclipse conventional compensation approaches, such as capacitor banks, in terms of flexibility and effectiveness. Despite their identified advantages, STATCOMs with voltage droop are subject to weak grid-induced stability problems, as first revealed by this paper. Specifically, the voltage droop controller that couples the amplitude of point of common coupling (PCC) voltages to the reactive current reference creates a local control loop. Such a loop greatly deteriorates system stability in weak grids, which feature large and variable grid impedances. To address such stability problems, we propose a novel virtual resistance control scheme, which improves system stability through mitigation of local control loop gains in the low-frequency band. Experimental results obtained from a DSTATCOM prototype clearly demonstrate the correctness of stability analysis and the effectiveness of stability improvement.
