| 摘 要： | 分析了传统短路比/有效短路比、多馈入直流输电短路比/有效短路比,以及多馈入相互作用因子的内在关系.对长三角多馈入直流输电系统进行等值,计算了各直流系统的传统短路比/有效短路比、多馈入短路比/有效短路比、多馈入相互作用因子,以及工频暂态过电压,并对淮南-上海特高压交流线路投产的影响进行了敏感性分析.研究表明长三角地区各直流系统之间相互作用较强,考虑多馈入因素后长三角地区受端系统仍属较强交流系统.

| Abstract: | The relationships of traditional short-circuit ratio(SCR)/ effective short-circuit ratio(ESCR),multi-infeed SCR/ESCR and multi-infeed interaction factor were analyzed.Based on that,the power system of Yangtze River Delta region was used as an equivalent typical multi-infeed HVDC model,and the traditional SCR/ESCR,multi-infeed SCR/ESCR,the multi-infeed interaction factor,and the transient over-voltage were calculated.The influence of Huainan-Shanghai UHV AC line was also analyzed.The study results showed tha... |
