Research on Critical SVG Technology for Low Voltage High Power Load

Abstract:

impact loads, such as submerged arc furnace, are often used in the smelting industry, their features include high power, low voltage, high current, rated power is from several MVA to tens of MVA, rated voltage is less than 200V. Reactive and harmonic compensation scheme for such load is generally centralized compensation on high voltage side of the power grid, facts have proved that, the effect of such compensation mode is not satisfactory to customers. Therefore, people have designed a special low voltage high power SVG, which is installed on the low voltage side for compensation, it could perform reactive power compensation, and filter out harmonic, protect against grid voltage fluctuation and flicker caused by submerged arc furnace in different production periods effectively.Compared with common SVG project, how to guarantee safe and stable operation of the equipment under high current conditions is critical technical issue in the design. This paper takes an example of an actual project, designs water-cooled copper pipe bus as connecting bus of low voltage high power SVG. Rationality and feasibility of this design has been proved in actual equipment operation.
