AI 中文摘要
抑制电力系统机电振荡最有效的方法之一，是通过附加在电力系统不同设备上的辅助控制器实现，具体为同步电机中的电力系统稳定器（PSS），或电力变流器设施中的电力振荡阻尼（POD）控制器。近年来，人们已对采用网侧跟随（GFL）控制的电压源变流器（VSC）中POD控制器的应用展开研究。尽管POD控制器在抑制电力系统区间振荡方面潜力巨大，但其正确实施并非易事，因为其有效性与参数设置密切相关。本文为实际电力系统应用场景下，电力变流器中POD控制器的实施提供指南。本文采用合成测试系统及西班牙监测合规性技术标准（NTS）中使用的系统方法，结合实际考量，提出POD控制器的合规性标准。文中还包含合成测试系统中POD控制器合规性标准的数值算例，分析采用具备网侧跟随（GFL）控制的通用电力变流器，通过仿真对采用有功功率注入调制的POD控制器（POD-P）、无功功率注入调制的POD控制器（POD-Q），或同时采用两者的POD控制器（POD-PQ）展开分析，相关结果已在大规模电力系统中得到验证。本文结论指出，通过采用合适的合成系统、方法及合规性标准，电力变流器中的POD控制器可有效抑制大规模电力系统的机电振荡。
英文摘要
One of the most effective ways to damp electromechanical oscillations in power systems is by means of supplementary controllers attached to the different devices in the power system is by means of power system stabilizers (PSS) in synchronous machines or by means of power oscillation damping (POD) controllers in facilities with power converters. In the recent years, the use of POD controllers in voltage source converters (VSCs) with grid-following (GFL) control has been investigated. Although the potential of POD controllers to help to damp inter-area oscillations in power systems is enormous, their correct implementation is not trivial, because their effectiveness is strongly linked to their settings. This paper provides guidelines for the implementation of POD controllers in power converters for application in real-world power systems. The paper proposes compliance criteria for POD controllers using a synthetic test system and a systematic methodology used in Spanish technical standard for monitoring compliance (NTS), considering practical considerations. The paper also includes numerical examples to illustrate compliance criteria for POD controllers in a synthetic test system. A generic power converter with grid-following (GFL) control is used for the analysis by simulation and POD controllers using modulation of active-power injection (POD-P), reactive-power injection (POD-Q) or both simultaneously (POD-PQ) will be analysed. Results were validated in a large-scale power system. The paper concludes that by using appropriate synthetic systems, methodologies and compliance criteria, POD controllers in power converters could be effective to damp electromechanical oscillation in large-scale power systems.
