The demand of electricity is continuously increasing due to increase in population and urbanisation. Due to lack of generation and transmission facilities there is over exploitation of present resources. The existing transmission lines are overloaded which make the system prone to stability problems. In the proposed work the power flow is increased in the existing system after using FACTS device using five different methods. They are firing by TCR pulse generator, using control subsystem based on RS Flip Flop, using Synchronised 6 pulse generator, using Thyristor -6 pulse generator with PLL, and pulse generator block of MATLAB.TCSC is used to control the dynamic power flow and also to enhance the power quality of the system. The power quality of the system is polluted due to use of common harmonic loads like computers, motor drives, arc and induction furnaces, battery charges, rectifiers, induction heating equipment. So, power electronics-based device TCSC is used in the proposed work. increases the efficiency of the line and improve the stability and security of the system. The active power at the receiving end is enhanced using the above different methods and the various results of power flow enhancement and THD analysis is shown. The THD analysis of the system is done in the present work using all the different methods. There provide other benefits to the system like damping power system oscillations, mitigating sub synchronous resonance, providing voltage support, improving transient stability.
