Single-Phase Series Compensator Circuit for Mitigating Voltage Sag or Swell in the Power System Networks - Methodology and Modelling

Nowadays, power quality becomes an essential concern in the field of power system networks due to the use of sensitive devices. The problem associated with power quality is voltage sag, damage to power equipment, product quality degradations, voltage swell, etc. But one of the severe disturbances in the power system is the problem of voltage sag. To mitigating these disturbances, the use of custom power devices or FACTS devices with the help of power electronic devices is presented. Hence an economical and proficient power device called as the Series Compensator Circuit (SCC) is employed in power distribution networks. This device helps in injecting the voltage in synchronism with the standard system voltage to compensate the voltage influences in the situation of voltage disturbance. This article deals with modelling, methodology and simulation of a Series Compensator Circuit (SCC). A simulation is modelled using MATLAB/Simulink. The simulation results are presented, which validates the functionality and the concept effectively.
