摘要:

新能源汇集地区广泛使用的电力电子设备容易产生大量次同步谐波，引发电力系统次同步振荡现象。为了实时监测及收集次同步振荡信息以研究振荡产生机理和控制方法，提出基于次同步谐波传播通道的PMU、SMU子站部署原则，将子站与WAMS主站呈辐射型互联构建广域次同步振荡监测系统。最后，将系统应用于新疆哈密地区后能实时精准、有效地监测到大量次同步振荡信息，直观地展示了次同步振荡的动态发展过程，为后续研究提供数据基础。

Abstract:

The power electronic devices which are widely used in the dense new energy areas are easy to produce a large number of subsynchronous harmonic, which leads to the subsynchronous oscillation in the power system. In order to monitor and collect subsynchronous oscillation information in real time to study the generation mechanism and control methods of oscillation, this paper proposes the deployment principle of PMU and SMU substations based on the subsynchronous harmonic propagation path, and connects the substations with the WAMS main station to build a wide area subsynchronous oscillation monitoring system. Finally, when the system is applied to Hami area of Xinjiang, the system can monitor a large number of subsynchronous oscillation information accurately and effectively, and intuitively display the dynamic development process of subsynchronous oscillation, so as to provide data basis for further research.
