AI 中文摘要
采用电力变流器的低频交流（LFAC）传输系统正被考虑用于多种应用。本研究探讨由下垂控制策略控制的LFAC传输线的小信号稳定性，采用特征值分析确定控制器下垂增益、工作频率、传输线参数及工作点如何影响系统稳定性。结果表明，系统整体动态由AC/AC变流器的下垂增益之和决定，还给出了揭示不同系统参数如何影响临界稳定点的分析结果，显示系统稳定性受线路长度、线路R/X比值、工作频率和电压的影响。
英文摘要
Low-Frequency AC (LFAC) transmission systems employing power converters are being considered for a varity of applications. This work studies the small-signal stability of an LFAC transmission line controlled by the Droop Control Strategy. Eigenvalue Analysis is used to determine how the controller droop gains, operating frequency, transmission line parameters, and the operating point affect system stability. The results show that the overall system's dynamic is governed by the sum of the droop gains of the AC/AC converters. Analytical results that give insights on how the different system's parameters affect the critical stability point are presented. The results indicate that system stability is affected by the line's length, the line's R/X ratio, operating frequency and voltage.
