Offshore wind farm collection grid with DC multiterminal internal fault analysis

The multi-terminal dc wind farm is a hopeful topology with a voltage source inverter (VSI) Connection at the onshore grid. This paper analyzes dc fault by using Differential Equation technique. The results are applicable for Voltage Source Converter(VSC)'s in the multi VSC dc wind farm collection grid and VSC based high voltage direct current (HVDC) cable transmission systems.
