Using Neural Network to Control STATCOM for ImprovingTransient Stability

Abstract

FACTS technology has considerable applications in power systems, such as; improving the steady state<br />performance, damping the power system oscillations, controlling the power flow, and etc. STATCOM is one<br />of the most important FACTS devices used in the parallel compensation, enhancing transient stability and<br />etc. Since three phase fault is widespread in power systems, in this paper STATCOM is used to improve the<br />transient stability of power system when three phase fault occurred. Neural Network has been used for<br />adjusting the gain of the supplementary controller of STATCOM. The simulation performed in MATLAB /<br />Simulink software. Simulation results showed when STATCOM combines with proposed Neural Network<br />based supplementary controller; the transient stability of power system improves.
