摘要(Abstract)：

宽频测量装置可有效实现电网宽频振荡实时监测，但在具体工程部署时缺乏针对性的指导方法，无法全面监测振荡及其传播，难以为振荡源定位提供参考。论述了当前振荡监测布点方法存在的缺陷，分析了PMU（同步相量测量单元）最优化配置方法与振荡监测布点方法的差异，提出了基于电网拓扑可观的振荡监测布点改进方法。对该方法的总体原则、总体思路和具体流程进行了论述，并结合典型拓扑案例验证了其可行性，最后给出了工程实施建议和思路。该方法能够为新型电力系统宽频振荡的监测、传播路径展示和振荡溯源提供参考。
Wide-frequency measurement devices can monitor wide-frequency oscillations in the power grid in real time. However, during practical engineering deployment, there is a lack of targeted guidance methods, making it difficult to comprehensively monitor oscillations and their propagation, and challenging to provide reference for oscillation source location. This paper discusses the flaws in current oscillation monitoring point distribution methods, analyzes the differences between optimal phasor measurement unit(PMU) configuration methods and oscillation monitoring point distribution methods, and proposes an improved oscillation monitoring point distribution method based on observable power grid topology. The overall principles, approach, and specific process of the proposed method are discussed, and its feasibility is verified with typical topology case studies. Finally, engineering implementation suggestions and ideas are provided. This method can serve as a reference for monitoring wide-frequency oscillations in modern power systems, displaying propagation paths, and tracing the source of oscillations.
