ANFIS based 48-Pulse STATCOM Controller for Enhancement of Power System Stability

Subir Datta and Anjan Kumar Roy

Abstract—The paper presents a new ANFIS-based controller for enhancement of voltage stability of a 500-kV, three-bus power system using a 48-pulse, ±100 Mvar GTO-based STATCOM. To study the effectiveness of the STATCOM in enhancement of voltage stability, the induced voltage of one of the generators is varied during simulation using programmable voltage source and the variations in voltage at the load end before and after the use of STATCOM is observed. The dynamic performance is studied using time-domain digital simulation of the complete system in MATLAB Simulink environment using its Power System Blockset (PSB). Control is carried out on a decoupled strategy using direct and quadrature components of STATCOM current. Operation of the STATCOM is validated in both capacitive and inductive modes. The complete power system, its PSB model and results of the investigations, showing the effectiveness of the proposed ANFIS-controller in voltage stabilization, have been presented with different figures. For the sake of comparison, time-domain simulation of the same system has been carried out with PI-controller and presented side-by-side. Analysis of the results and a conclusion are presented.

Index Terms—48-pulses GTO based STATCOM, Voltage Stability, Reactive power compensator, ANFIS and PI controller, Decoupled control strategy.
