Abstract

VSC based Multi-terminal HVDC transmission is employed for the integration of offshore wind and wave farms. Flexibility, reliability and reduced transmission losses are the main/primary reasons for preference of MTDC networks. The transmission layout still suffers from some drawbacks, of which the most prominent is fault ride through capability in terms of its response to either a temporal or permanent loss of converter station(s). This paper presents the simulation analysis of hysteresis based and PI- based DC grid voltage control techniques for fault ride through capability of a 4 terminal HVDC network (MTDC), which consisted of a wind farm, wave farm and two onshore converters. The analysis showed that the PI method resulted in a faster response time as well as smaller overshoots and dips when a three phase to ground fault occurs. A detailed electromagnetic transient (EMT) study was performed using MATLAB/Simulink.
