Design of static synchronous compensator statcom based on neuro-fuzzy logic control

الملخص EN

One of major issues involved in power transmission are enhancing the capability of transfer the active power through the existing transmission system and flexible control of power flow through these transmission lines.

To achieve these goals the use of solid-state devices for reliable operation and faster control.

The power electronics devices are utilized to control the flow of power these are classified under the flexible ac transmission systems (FACTS).

Static synchronous compensator (STATCOM)is a FACTS device, STATCOM is designed by solid state device based on voltage source inverter(VSI), provide a controllable compensating voltage over the identical range of inductive and capacitive independent of the line current.

In this study, a design scheme of STATCOM by utilize Neuro-Fuzzy logic controller is proposed, Sugeno type fuzzy logic, by using off-line rules are trained, also, d-q theory was used to calculate the parameters of power system due to its less computation and high accuracy.

The simulation results show the proposed controller is reliable and robust compared to the conventional controllers where it needs less than cycle to reach the steady state and also less oscillation
