Abstract: Applications of FACTS devices for line flow controls, active and reactive power flow controls, loss component control, flexibility in operation & control. To reduce this power quality problems of distribution system, there are no. of power quality solutions techniques by using FACTS controllers, by use of new available power electronics devices. There are no. of factors affect the over voltage. This is effect, which is the voltage value at receiving end of lines is greater than giving point. This occurs because of capacitance charging current resulting over voltage increase with respect to the increase line length. The project is design to implement FACTS with TCR (Thyristor Controlled Reactance).This method is used if low load is there or no load. Because of this, very low flow o current through line and shunt capacitance become dominant. This causes Ferranti Effect, that means receiving end voltage value may be becomes greater than sending voltage (generally for very long transmission lines). To reduce that effect, inductors are automatically connected across line.
