摘要: This paper presents a digital network analyzer technique to actively monitor the proposed MVDC distribution system for US Navy's all-electric ship by using existing power electronic converters make wideband measurements of small-signal transfer functions and impedances. The themselves become excitation source analysis tool detecting changes in converter dynamics information can be used fault detection localization, stability performance improvement adaptive control, distributed control. correlation-based is examined its application obtaining several converter-level system-level terminal characteristics. A scheme an control platform described that able correct multiple information-rich frequency response data obtained through identification procedure. Simulation results are provided realistic scenarios, which targeted adaptation prevents instability improves performance.
