中文摘要:

随着风电场接入电力系统的占比增高，风电场内部或风电场与电网之间交互引发次同步振荡问题也日益突出。风电并网系统电力电子装置应用广泛、控制环节复杂多样、交直流混联输电，导致次同步振荡的监测和控制难度较高。基于数据驱动的方法根据风电并网系统运行数据之间的关联性挖掘次同步振荡的特征，从数据的角度实现次同步振荡在线分析，为保障电网的安全稳定运行提供了新的研究思路。文中梳理了近年来国内外的研究成果，从次同步振荡模态参数辨识、广域相量计算、系统运行状态分类、系统参数估计四个角度综述了基于数据驱动的风电并网系统次同步振荡在线分析方法的研究现状，对各种方法在风电并网系统次同步振荡监测、状态评估、预警、溯源、传播等多个场景的应用进行了归纳和分析，总结了各类方法在线应用的优势和局限性，针对现有方法在未来风电并网系统次同步振荡问题的研究和应用进行了展望。

英文摘要:

With high proportion of the wind farms connected to the power system, subsynchronous oscillation resulting from the interaction within the wind farms or between the wind farm and the power grid becomes increasingly prominent. It is difficult to online monitor and control subsynchronous oscillations due to broad application of the power electronics, complex and diverse control links and AC/DC hybrid connection in modern power grids. The data-driven method mines the characteristics of subsynchronous oscillation according to the correlation between the operation data of wind power grid-connected system, and realizes the online analysis of subsynchronous oscillation from the perspective of data. As a result, a new research idea for ensuring the secure and stable of power grid is provided. This paper reviews the research results both from China and foreign countries in recent years. From four aspects of modal parameter identification, wide-area phasor calculation, system operating state classification, and system parameter estimation, the research status of data-driven online analysis methods for subsynchronous oscillation in wind power grid-connected system are summarized. The application of various methods in multiple scenarios such as subsynchronous oscillation monitoring, state assessment, early warning, source tracing and propagation of wind power grid-connected system is summarized and analyzed. Based on the results, the advantages and limitations of online application of various methods are summarized. The research trends and application prospects of the existing methods on the subsynchronous oscillation of wind power grid-connected system are prospected.
