Low Frequency Ac Transmission System for Offshore Wind Farm by Using DC/AC/AC Converter

K. Jaghannath


The possible solutions for transmitting power from wind farms are HVAC, Line commutated HVDC and voltage source based HVDC (VSC-HVDC). In this paper Low Frequency AC (LFAC) transmission system is used for interconnecting the offshore wind farms for improving the transmission capability and also the dc collecting system with series connected wind turbines are used at the offshore to reduce the cabling requirement. A method to design the systems components and control is set forth. Simulation results are provided to illustrate the systems performance.
