摘　　要：基于两机系统模型分析提出大区互联系统区域间振荡频率特性变化主要受互联系统总容量、互联子系统容量比、互联系统间的交换功率、互联系统间联系电抗等因素的影响,并基于WAMS的实测数据,应用理论分析的结论对华中-华北1000kV特高压联络线运行两年以来的频率变化情况进行了分析。Based on two-source system model analysis,this paper proposes the major factors that influence oscillation frequency characteristic variation of inter-regional interconnected system as the total system capacity,sub-capacity ratio,power exchange between interconnected power grids,reactance between the grids,etc.Based on the WAMS measured data,above conclusion is applied in analyzing the frequency variation on Central China-North China 1000kV UHV link line in two years of operation.
