D-STATCOM MODELING AND SIMULATION APPLYING CONTROL SCHEMES FOR POWER QUALITY IMPROVEMENT

This paper focuses to design and analyze the Simulink model for the control of Distributed static synchronous compensator (D-STATCOM). It is important for a distribution system to have controllability, voltage stability and good power transfer capability. The voltage source converter based D-STATCOM achieves voltage regulation in the system by absorbing or supplying the required reactive power. The system is modeled using two control strategies, i.e., direct and indirect control which includes d-q transform. The comparative analysis of the control strategies has been done. The results of simulation are demonstrated and analyzed using MATLAB
