Abstract
In recent years the use of nonlinear loads in the distribution system has increased drastically. Due to these nonlinear loads, power quality problems occurs in the system. Distribution Static Compensator (DSTATCOM) is a voltage source converter based shunt connected custom power device, used in distribution system for performance improvement. DSTATCOM will maintain constant voltage at load terminals and limit the Total Harmonic Distortion (THD). This paper presents a case study on investigation of performance of DSTATCOM at different operating scenarios. IEEE 13 bus industrial system is used to study the performance of three leg DSTATCOM. Voltage control mode with PI controller is used to control RMS voltage at Point of Common Coupling (PCC). PSCAD/EMTDCTM tool is used to study the performance. From the study it is found that DSTATCOM is able to maintain voltage at 1 pu.
