Power quality improvement in transmission systems using facts devices

摘要

Normally the power is generated by conventional form of energy either by non-conventional form of energy. The generated power can be transmitted by different types based on the type of transmission network preferred. while transmitting the power due to some power quality problems like sag or swell will arise and there will be a drop in voltage that produces the oscillating waves that results in low power factor. In earlier days to overcome this mechanical circuit breakers are used as solver where it is made up of relays and contractors that compensating is not reliable. To inject voltage or current in a transmission network FACTS devices are more popular to solve the problems. In this paper the performance of different types of devices have been used to solve the drawbacks by injecting the voltage and to control the power flow and other parameters.
