IEEE 118-bus Transient Event Data

This is the simulated post fault voltage magnitude transient data from the IEEE 118-bus system. The data is collected from the TSAT software (DSATool). This transient data is used to mimic the PMU voltage measurements. This file has three folders. The first folder 'Train_Test' has the training and testing data. The dimension of the training data 'Pro2_train_v.pkl' and testing data 'Pro2_test_v.pkl' are (8000x25x20) and (2000x25x20), respectively. Here the number of training and testing samples is 8000 (4000 stable, 4000 unstable) and 2000 (1000 stable and 1000 unstable). 25 is the length of the data, representing 25 cycles of PMU voltage magnitudes after the clearance of the fault (It is assumed that the sampling frequency of the PMUs is 120 messages per second). 20 is the number of buses that are deployed with PMUs. Locations of the PMUs are written in the readme file. The other two files, i.e., 'Pro2_test_label_new.pkl' and 'Pro2_test_traini_label_new.pkl', are the label of the testing and training dataset. The dimension of these two files are (2000x2) and (8000x2). Here, we use the vector [0,1] to represent stable, and [1,0] as unstable. The stability of the transient is determined by the angle-based stability index. The second folder is different_location. 5 different locations are considered. Locations of the PMUs are given in the readme file. The third folder is different_number. 7 different numbers of PMUs are considered. Information of the number of PMUs is written in the readme file. Note, all the training and testing data files use the same label files, i.e., 'Pro2_test_label_new.pkl' and 'Pro2_test_traini_label_new.pkl'.本数据集为IEEE 118节点电力系统故障后的仿真电压幅值暂态数据，数据采集自TSAT软件（DSATool）。该暂态数据用于模拟同步相量测量单元（PMU）的电压幅值测量结果。本数据集包含三个文件夹：第一个文件夹"Train_Test"内存储训练与测试数据，其中训练数据文件"Pro2_train_v.pkl"与测试数据文件"Pro2_test_v.pkl"的维度分别为(8000×25×20)与(2000×25×20)。训练集与测试集的样本量分别为8000（4000个稳定工况、4000个不稳定工况）与2000（1000个稳定工况、1000个不稳定工况）。维度参数中，25代表数据长度，对应故障清除后PMU采集的25个周期的电压幅值（假设PMU采样频率为每秒120条报文）；20代表部署了PMU的母线总数。PMU的安装位置详见README文件。另外两个文件"Pro2_test_label_new.pkl"与"Pro2_test_traini_label_new.pkl"分别为测试集与训练集的标签文件，二者维度分别为(2000×2)与(8000×2)。本数据集采用向量[0,1]表征稳定工况，[1,0]表征不稳定工况，暂态稳定性由基于功角的稳定性指标判定。第二个文件夹为"different_location"，共考虑5种不同的PMU安装位置，相关位置信息详见README文件。第三个文件夹为"different_number"，共考虑7种不同的PMU部署数量，相关部署信息详见README文件。需注意，所有训练与测试数据文件均使用同一套标签文件，即"Pro2_test_label_new.pkl"与"Pro2_test_traini_label_new.pkl"。
