Research of energy efficiency evaluation parameters for power quality control device based on IGBT module

In this paper, the energy efficiency evaluation parameters for power quality control device based on IGBT modules have been discussed. First of all, energy consumption of the typical power quality control equipment, such as SVG, APF and MEC, under the rated conditions, have been analyzed to identify the main energy-consuming parts. Then, energy loss mechanism and energy saving path of IGBT module have been discussed. And the energy saving improvement direction of the power quality control equipment based on IGBT module is identified at the same time. At last, the applicable energy efficiency evaluation parameters for power quality control device have been selected, based on the research of the product performances for energy efficiency of power grid.
