IEEE 39-bus PMU measurements of 10 generators

The dataset contains PMU measurements of all ten generators of IEEE 39-bus transmission system model, installed at the generators terminal. The dataset was obtained by using RTDS power system simulator and GTNETx2 based PMUs, and was stored by using Synchro-measurement Application Development Framework (SADF) Matlab library. Dataset constructs in total 86.6s of simulation and 5197 PMU measurements per generator. The dataset contains PMU measurements of the following three use-cases, executed consecutively in one simulation: A. Quasi-steady-state operation, where generator G1 mechanical torque is being modulated every 200 ms with a random perturbation within ± 1 % of the nominal value. B. Quasi-steady-state operation + change in topology (2 times) caused by the applied three-phase self-cleared fault on bus B25 with permanent tripping of line B2-B25 and the delayed line B2-B25 reconnection. C. Quasi-steady-state operation + temporal perturbation caused by the three-phase self-cleared fault on bus B14. Use-case A continues with the use-case B. In the use-case B, a fault is applied, leading to line B2-B25 permanent disconnection. This results in the topology change. Moreover, approximately 37 s after the fault, the line B2-B25 is reconnected to restore the initial topology (as in the use-case A). Finally, in use-case C, the quasi-steady-state conditions, as in use-case A, are followed by a three-phase 80 ms self-cleared fault on bus B1.

本数据集包含IEEE 39节点输电系统模型全部10台发电机的同步相量测量单元（PMU，Phasor Measurement Unit）实测数据，测点部署于各发电机机端。数据集通过RTDS电力系统模拟器与基于GTNETx2的同步相量测量单元采集得到，并采用同步测量应用开发框架（SADF，Synchro-measurement Application Development Framework）Matlab库完成存储。本次仿真总时长为86.6秒，每台发电机对应5197条PMU测量数据。

本数据集包含三类连续执行于同一次仿真中的应用场景：
A. 准稳态运行场景：对发电机G1的机械转矩每200毫秒施加一次调制，扰动幅度为额定值±1%的随机值。
B. 准稳态运行+拓扑变化场景（共2次）：在母线B25处施加三相自清除故障，引发线路B2-B25永久跳闸并延迟重连，由此产生两次拓扑变化。场景A接续场景B执行：场景B中先施加故障，导致线路B2-B25永久断开，引发拓扑变化；故障发生约37秒后，线路B2-B25恢复连接，以还原场景A中的初始拓扑结构。
C. 准稳态运行+暂态扰动场景：在母线B14处施加三相自清除故障，引发暂态扰动。最终，场景C以与场景A一致的准稳态运行条件为基础，在母线B1处施加持续80毫秒的三相自清除故障。
