【Abstract】The harmonic and reactive power are two factors which affect the power quality of the Mine Hoist power system. Hoist is the main energy-consuming equipment of mines. As the load rectification equipment can produce reactive power and harmonic. In order to solve the power quality problem which is brought by harmonic and reactive power，and that effect other electric equipment and users. According to Hoists load characteristic, the paper proposed a harmonic suppression and reactive compensation scheme which is made up of SVG (Static Var Generator) and FC (Fixed Capacitor) .The paper has also introduced the compensation principle and capacity computing method of SVG. Whats more, this article has elaborated design principle and parameters setting method of FC filter branch. By analysis the advantages of SVG and the governance effect to power quality after implementing join compensation scheme. The result has proved that the SVG+FC join compensation scheme is effective.
