Abstract

This paper demonstrates the design of Permanent magnet Synchronous Generator (PMSG) suitable for offshore Wind farms and reviews the state-of-the art and highly applicable mechanical position/speed sensor less control schemes for PMSG-based variable-speed Wind Energy Conversion Systems. In these Voltage Source Converters (VSC) Multi Terminal High Voltage Direct Current (HVDC) transmissions technology is used to integrate with main grid. Due to enormous advantages of VSC system, it facilitates fast Active and Reactive power control and relatively lower losses. VSCs have a limited transmission capacity due to limitations on IGBT and capacitors ratings. For these reasons, a multi-terminal HVDC (MTDC) transmission system, which can extract and deliver power from and to several terminals and provide power to more than one terminal, is an attractive method for offshore wind power transmission. MTDC system and the results show that the system can operate effectively under a variety of operating conditions.
