新型电力系统宽频振荡监测布点方法研究OA

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 os-cillation 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 imple-mentation 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.
