The paper deals with hardware-in-the-loop (HIL) laboratory setup consisting of the arbitrary waveform generator (AWG) and the device used for grid voltage fundamental harmonic amplitude and frequency real-time (RT) estimation. The device under test (DUT) is realized as desktop target PC with Phar Lap RT operating system using NI PCIe 6251 DAQ card. On the other hand, the AWG serves as a three-phase or single-phase grid disturbance simulator. The algorithm based on the linear Kalman filter and the frequency-locked loop has been used as robust and accurate estimation technique. Both AWG and DUT have been driven from the host PC. Furthermore, LabViewallows user to configure and perform remote online monitoring of the DUT, i.e., to track amplitude and frequency changes point-by-point on the host PC over Ethernet TCP/IP protocol. The AWG allows various real-time case study analysis to be performed in accordance with up to date power quality standards. For a selected case studies, the DUT is verified by comparing experimental results against IEEE and IEC standards for power quality analysis. An example of grid voltage amplitude and frequency online monitoring is also presented. Moreover, proposed HIL laboratory setup can be used for comparison of various estimation techniques for control and protection purposes in microgrids.

This dataset contains phasor measurements (PMU-type) signals from the IEEE New England 39-bus power system test case network, which are generated from a large corpus of systematic MATLAB®/Simulink electro-mechanical transients simulations. It was prepared to serve as a convenient and open database for experimenting with different types of machine learning (including deep learning) techniques for transient stability assessment (TSA) of electrical power systems. A dataset contains time-domain signals from 9360 simulations. Different load and generation levels of the New England 39-bus benchmark power system are systematically covered, as well as all three major types of short-circuit events (three-phase, two-phase and single-phase faults) in all parts of the network. The consumed power of the network was set to 80%, 90%, 100%, 110% and 120% of the basic system load levels (for different system load levels, both generation and loads are scaled by the same ratio). The short-circuits are located on the busbar or on the transmission line (TL). When they are located on a TL, it was assumed that they can occur at 20%, 40%, 60%, and 80% of the line length. Timing of the fault occurrences takes into the consideration a moment on the instantaneous sinusoidal reference voltage. The observation period of each simulation was set at 3 seconds and signals are sampled at 1/60 s resolution. Many different machine electrical and mechanical (rotor and stator quantities), as well as network (three-phase currents and voltages), time-domain signals are obtained from simulations with a PMU-type resolution.
