Principle Structure of FFTS Application Conclusion References INTRODUCTION HVDC system FACT( flexible AC transmission system) Fractional frequency transmission WHY FRACTIONAL FREQUENCY? Better voltage regulation Improved capacity Lesser voltage fluctuations Improved stability WHY FRACTIONAL FREQUENCY? Better voltage regulation Improved capacity Lesser voltage fluctuation Improved stability PRINCIPLE Factors limiting transmission capacity 1) Thermal limit 2) Stability limit 3) Voltage drop limit Stability limit Voltage drop limit APPLICATIONS FFTS is particularly applicable for transmitting electricity generated by renewable energy sources -Integrating wind farms via FFTS ADVANTAGES The investment in transmission system can be reduced Wind power generator will be simplified Gear ratio can be reduced Number of poles can be reduced Replacing converter of each variable speed wind generator by the cycloconverters of FFTS More wind energy can be trapped The voltage fluctuation induced by the wind power will reduced CONCLUSION It is an efficient approach to overcome inherent difficulties of conventional system: Voltage regulation Stability Voltage fluctuation etc. By the use of FFTS we can increase transmission capacity (3 times) The operating performance will be improved The economic profit will also increase
