Impact of Carrier Frequency in SSFC Controller with Grid Inter-Connected Wind System

This chapter presents the impact of carrier frequency in the proposed FACTS based Static Switched Filter Compensator (SSFC) scheme incorporated wind energy system with efficient power quality enrichment. With the increasing of population, the energy source demands are also increases. The amount of energy requirement is different between the countries around the world. The developed country need more energy compare to developing country. Analysis is done for the proposed system by varying Carrier frequency over a wide range and observed system performance at all 3 busses wise Grid bus, Generator Bus and Load Bus. In this paper analysis is done for different carrier frequencies at busses wise Grid bus Generator Bus, Load Bus of the proposed Grid connected wind system with FACTs –SSFC and it is observed in the range of 500Hz to 10000Hz. Two regulators are used to organize the FACTS SSFC-device, these are based on a tri-loop dynamic error obsessed inter-coupled input to VSC controller. It is clear from the analysis that carrier frequency is varied from 500Hz to 10,000Hz. There is very less variation in voltages and currents percentage THDs at all busses expect at load buses that too for current THDs. For this reason, the power lines besides communication lines are not affected by the noise signals and hence Power Quality is Improved.
