Development of Intelligent Controllers for STATCOM

To study and analyze the dynamic performance of the flexible AC transmission system (FACTS) devices, modelling of the FACTS devices is needed. Reactive power compensation is an important issue in the control of electric power systems. Reactive power increases the transmission system losses and reduces the power transmission capability of the transmission lines. Moreover, reactive power transmitted through the transmission lines can cause large amplitude variations in the receiving-end voltage. This paper illustrates the effect of static compensator (STATCOM) in power system on reactive power control by proper modelling of simple power system and voltage source converter based STATCOM (Static compensator) using Simulink and Simpower system toolboxes in MATLAB. The proposed control structure is also verified via state- of- the- art dSPACE software.
