Analysis and improvement of the ‘5.26’ bipolar trip of Yun-Guang HVDC islanded operation


Islanded operation of HVDC sending system can reduce the influence of HVDC fault on the parallel AC system, enhance the security of the system and increase the transmission capacity. Due to relatively small system inertia and ESCR, there are difficulties of the frequency and voltage control in the islanded sending system. The conventional analysis are… (More)
