    <subfield code="a">&lt;p&gt;This dataset contains phasor measurements (PMU-type) signals from the &lt;strong&gt;IEEE New England 39-bus power system&lt;/strong&gt; test case network, which are generated from a large corpus of systematic &lt;strong&gt;MATLAB&amp;reg;/Simulink&lt;/strong&gt; electro-mechanical transients simulations. It was prepared to serve as a convenient and open database for experimenting with different types of &lt;strong&gt;machine learning&lt;/strong&gt; (including deep learning) techniques for &lt;strong&gt;transient stability assessment&lt;/strong&gt; (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.&amp;nbsp;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.&lt;/p&gt;

&lt;p&gt;A &lt;strong&gt;dataset&lt;/strong&gt; is a collection of MAT files (.mat) which can be imported into the MATLAB&amp;reg; Workspace.&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;The database consists of 9360 simulations (15x624 simulations) separated into &amp;quot;.mat&amp;quot; files.&lt;/li&gt;
	&lt;li&gt;Every database or packet of 624 simulations has a different nickname. Nickname is an abbreviation for a specific condition that has been observed (i.e. simulated) in that specific case.&lt;/li&gt;
	&lt;li&gt;Filenames reveal network conditions. Load denotes load level of the system in % and SC denotes type of short-circuit where 1, 2 and 3 are single-phase, double-phase and three-phase short-circuit, respectively. For example, Load_80_SC_1_OUTPUT.mat filename has the following meaning: Load_80 means that the consumed power was set to 80% of the basic system load level and SC_1 means that a single-phase short circuit has been observed.&lt;/li&gt;
&lt;/ul&gt;
