Abstract

Electrical power generated in an offshore wind farm is transmitted to an onshore grid through submarine cables, in which there are two transmission methods, that is, high voltage alternate current (HVAC) and high voltage direct current (HVDC) transmission systems. HVAC transmission system has already been adopted in many offshore wind farms. HVDC transmission system is suitable for long distance power transmission. This paper presents a comparative analysis on the transient stability of the offshore wind farm connected to an onshore grid through HVAC or HVDC system for a ground fault on the onshore grid.
