Abstract:

This Paper concentrated on the static compensator utilizing a two level cascaded multi level inverter implemented for reactive power compensation. The technique consisting of two level designed inverters are integrated in cascaded manner with help of open ended windings from the three phase transformer. The capacitor acts as a dclink capacitance which is used to control the generation of voltage from the STATCOM. Here fuzzy logic controller which is used to control and regulate the generation of voltage levels from the STATCOM by the fuzzy rules and conditions. The simulink models are tested and verified within the MATLAB/SIMULINK. The implemented models are controlled and compensated the abnormal conditions to normal conditions. The presence of Fuzzy controller the disturbances normalized which enhances system performances.
