IEEE 39-bus PMU measurements of 10 generators

The dataset contains PMU measurements of all ten generators of IEEE 39-bus transmission system model. The dataset was obtained by using RTDS power system simulator 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. 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. 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, which also affects the groups of slow coherent generators. Moreover, approximately 37 s after the fault, the line B2-B25 is reconnected to restore the initial topology (as in the use-case A) which also affects the generator coherency. It can be concluded, that the topology change (line disconnection) leads to coherency change, which returns to its initial configuration after the line is put back to operation (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节点输电系统模型中全部10台发电机的相量测量单元（PMU, Phasor Measurement Unit）测量数据。本数据集通过RTDS电力系统仿真器采集，并使用同步测量应用开发框架（SADF）Matlab库进行存储。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。 本数据集涵盖单次仿真中连续执行的以下三类应用场景的测量数据： A. 准稳态运行场景：以每200毫秒的频率对发电机G1的机械转矩进行随机调制，扰动幅值为额定值的±1%。 B. 拓扑变更场景：在母线B25处施加三相自清除故障，导致线路B2-B25永久性跳闸，由此引发两次拓扑变更；故障发生约37秒后，延迟恢复该线路的连接，以回归场景A的初始拓扑。该场景的拓扑变化会影响慢速同调发电机群的分组特性，而线路恢复运行后，发电机同调性将回到初始状态。场景A接续场景B执行。 C. 暂态扰动场景：由母线B14处的三相自清除故障引发的暂态扰动。最终，在场景C中，系统先恢复至场景A的准稳态运行条件，随后在母线B1处施加持续时长80毫秒的三相自清除故障。
