Abstract: Nowadays, reactive power control has been playing a vital role in a systematic study of maintaining a secure voltage limit in the transmission system. When large inductive loads are connected in the transmission line then the matter of poor power factor is faced because of lagging load current. Sometimes, due to a small load, very low current flows through transmission line causing in a leading shunt capacitance in transmission line result increase in voltage to the receiving end voltage may become twice of the sending end voltage (Ferranti effect), in a long transmission line. To minimize these issues we are using a parallel combination of thyristor switched capacitor (TSC) and thyristor controlled reactor (TCR). The microcontroller/ Arduino is used to vary the firing angle of thyristor then we get smooth current control range from capacitive to inductive value. This paper shows the study of FACTS devices (TSC-TCR) which are used to control reactive power n electrical power system to improve the power quality as well as enhance the power transfer capability.
