摘要：
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. © 2019, Power System Technology Press. All right reserved.
