摘要
电力系统低频振荡问题是互联电网广泛使用快速自动稳定装置后开始出现的,具有突发性和瞬时性,对电网安全稳定运行构成严重威胁。特别是近年来国内外频繁出现各种新的振荡模式,迫切要求对低频振荡进行深入了解并提出有效的解决措施。在相关文献的基础上,分析了低频振荡的机理和影响因素,介绍了现有的分析方法和抑制措施,并结合当前我国特高压智能电网背景列举了若干研究热点,为进一步研究系统低频振荡提供参考。
The problem of power system low frequency oscillation appears after automatic express stabilizers devices being widely used in interconnected power system,accompanied by sudden and transient characteristics,which poses a serious threat to the safety and stable operation of power grids.Due to a variety of new oscillation modes occurred frequently at home and abroad in recent years,in-depth understanding of low frequency oscillations and some effective resolution measures are urgently needed.Based on related literatures,this paper analyses the mechanism and influencing factors of low frequency oscillation,introduces several existing analysis methods and suprression measures,and lists a number of reserach focus on UHV smart grid,aiming at providing a reference for rurther study.
