Power System Transient Stability Assessment Simulations Dataset - IEEE New England 39-bus test case

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. A dataset is a collection of MAT files (.mat) which can be imported into the MATLAB® Workspace. The database consists of 9360 simulations (15x624 simulations) separated into ".mat" files. 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. 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.

本数据集包含源自IEEE新英格兰39节点电力系统测试案例网络的相量测量类（PMU，phasor measurement unit）信号，此类信号通过大规模系统性MATLAB®/Simulink机电暂态仿真语料生成。本数据集旨在构建便捷开源的数据库，用于开展各类机器学习（含深度学习）技术在电力系统暂态稳定评估（TSA，transient stability assessment）中的实验研究。

本数据集包含9360组仿真的时域信号。其系统性覆盖了新英格兰39节点基准电力系统的各类负荷与发电水平，同时涵盖了网络全区域内三种主要短路故障类型：三相短路、两相短路与单相短路。系统消耗功率设定为基准系统负荷水平的80%、90%、100%、110%与120%（针对不同系统负荷水平，发电与负荷均按相同比例缩放）。短路故障可发生于母线或输电线路（TL，transmission line）：若故障发生于输电线路，则假定其可出现在线路长度的20%、40%、60%与80%位置处。故障发生时刻需结合瞬时正弦参考电压的相位确定。每组仿真的观测时长设定为3秒，信号采样分辨率为1/60秒。

本数据集通过仿真获取了多种不同的电机电气与机械量（转子与定子相关物理量）以及网络量（三相电流与电压）的时域信号，采样分辨率符合PMU类标准。本数据集以MAT文件（.mat）格式存储，可直接导入MATLAB®工作区。该数据库包含9360组仿真数据（分为15组，每组624组仿真），每组对应一个“.mat”文件。每624组仿真的数据包拥有不同的昵称，该昵称为该组仿真所对应特定工况的缩写。文件名可体现网络工况：Load表示系统负荷水平（以百分比计），SC表示短路类型，其中1、2、3分别对应单相短路、两相短路与三相短路。例如，文件名Load_80_SC_1_OUTPUT.mat的含义如下：Load_80表示系统消耗功率设定为基准负荷水平的80%，SC_1表示发生单相短路故障。
