Impact of DC Grid Topology on Transient Stability of HVDC-Segmented Power System

• This paper compares the effects of ring, radial and interconnected DC grid topologies on the transient stability of a segmented 15 - bus electric grid for different HVDC schemes. For this purpose, three HVDC convertor technologies and four HVDC station configurations are considered. A three phase AC bus fault is applied and the rotor angle disturbance is analyzed. The results show that the transient stability is dependent on the topology for bipolar configuration of line commutated current source and capacitor commutated convertor technologies. For rest of the HVDC schemes, transient stability is independent of the topology used.
