The Study of VSC-HVDC System Simplified Model on Large Offshore Wind Farm

VSC-HVDC is one of the proven solutions to the transmission problem of offshore wind power and the study of converter is the key technology. Mean value model of converter is introduced. The paper puts forward a method that can simplify the complex converter which is based on IGBT into a mean value model to improve the simulation speed. Through the simulation in Mat lab, the accuracy and high efficiency of simplified model are verified. The results show that the simplified model is feasible.
