PMU measurements of IEEE 39-bus power system model
收藏资源简介：
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节点输电系统模型中全部10台发电机的同步相量测量单元（PMU，Phasor Measurement Unit）实测数据，测量点布置于各发电机机端。本数据集通过RTDS电力系统模拟器与基于GTNETx2的PMU采集得到，并使用同步测量应用开发框架（SADF，Synchro-measurement Application Development Framework）Matlab库进行存储。本次仿真累计时长86.6秒，每台发电机对应5197条PMU测量数据。 本数据集包含以下三类连续执行于同一次仿真中的场景对应的PMU测量数据： A. 准稳态运行场景：每200ms对发电机G1的机械转矩施加其标称值±1%范围内的随机扰动，实现转矩调制。 B. 准稳态运行+拓扑变更场景（共触发2次拓扑变化）：在母线B25处施加三相自清除故障，致使线路B2-B25永久跳闸；随后延迟恢复该线路的连接，完成拓扑复原。 C. 准稳态运行+暂态扰动场景：由母线B14处的三相自清除故障引发暂态扰动的准稳态运行模式。 本次仿真中场景A接续场景B执行。在场景B中，首先施加故障致使线路B2-B25永久断开，引发拓扑变更；故障发生约37秒后，恢复线路B2-B25的连接，以复原场景A中的初始拓扑结构。最后，在场景C中，先维持与场景A一致的准稳态运行条件，随后在母线B1处施加持续80ms的三相自清除故障。
