In view of such problem of general LC capacitor bank of the current traditional traditional reactive power compensation equipment as lag of response load variation

insufficient control accuracy and of Static Var Generator（SVG）with superior dynamic performance but excessive cost

in this paper

the hybrid compensation system based on SVG+LC is proposed with combination of the feature of original LC capacitor bank compensation equipment

which can coordinate and control LC and SVG to accurately compensate the load reactive power. At the same time

in view of the defects in conventional double closedloop PI regulation of SVG and of interaction with LC in coordination and operation

a kind of fuzzy-improved PI dual-mode controller and a synergic adjustment strategy between SVG and LC are proposed. It is shown by the Simulink simulation waveform that the hybrid compensation system based on SVG+LC has good compensation performance and can meet the requirements of reactive power compensation of power system.
