Hardware implementation and simulation of single phase TCSC at laboratory scale level

The aim behind writing this paper is to understand the significance of thyristor controlled series capacitor (TCSC) in the transmission line for the augmentation of active power and to reduce the transmission line losses up to a possible extent. The TCSC device (Member of FACTS family) is responsible for the enhancement of active power by compensating the need of reactive power, improving the transmission line stability, and reducing the heavy loading of the transmission line. TCSC is a series controlled device which is applied to the AC transmission in order to acquire smooth control of series reactance and direct control of power flow. In this paper simulation and hardware of single phase, TCSC has been described. Least square identification method has been performed to decide the value of inductor and resistor of a constructed air-core winding. Laboratory model for the single-phase TCSC system is implemented using Arduino Uno and it is further tested by loading the pulse generation programme in Arduino Uno. The Pi transmission line has been constructed and implemented for single-phase voltage level. The simulation of single phase TCSC has been compiled in MATLAB R2014a software. Finally, the validation was done by comparing the results of simulation and hardware.
