摘要
受端系统电压支撑强度因子(receive-end-systemvoltagestrengthfactor,RVSF)是受端系统的电压支撑强度的评价指标,可以计及受端系统中不同电力系统元件特性和运行方式。首先提出了在柔性直流输电系统不同控制方式下受端系统RVSF的解析计算方法;然后在混合多馈入系统中对比分析了RVSF、有效短路比、多馈入有效短路比等评价指标,表明RVSF具有相关性强且临界值明确的优点;最后应用解析计算方法计算RVSF值,并分析归纳VSC-HVDC对LCC-HVDC受端系统强度的影响规律。研究结论可用于混合多馈入系统的规划和运行。
The effect of receiving-end-system voltage strength factor (RVSF) on characteristics and operation modes of different power system components in end-to-end system can be used as a index of the strength of the receiving system to study the effect of VSC-HVDC on strength of LCC-HVDC end-to-end system in a hybrid dual feed system. In order to facilitate research, analytical calculation method of RVSF under different control modes of VSC-HVDC is proposed. The RVSF values of VSC-HVDC in different control modes, and active power and reactive power of different transmission and different drop points are calculated, and the influence of these factors on the strength of LCC-HVDC receiving end system is analyzed. The conclusion can play a guiding role for planning and operation of hybrid multi-infeed system containing VSC-HVDC and LCC-HVDC.
