摘　　要：在建立新型电力系统的大背景下,海量的新能源和电力电子器件并入地区电网带来了新的稳定性挑战——宽频振荡。通过介绍近年来新能源机组并网引发的振荡事件,从宽频振荡产生原因、分析方法和抑制措施阐述了由大规模电力电子设备接入电网引起的振荡稳定性问题。In the context of establishing new-type power systems,the integration of massive new energy generations and electronic devices into regional power grid has brought about new stability challenges,i.e.,broadband oscillation.This paper outlines the oscillating incidents caused by new energy generation connection in recent years,and summarizes oscillating instability caused by large-scale electric equipment to power grids.
