| In order to solve the power quality problems such as system voltage fluctuation, power factor reduction and line loss increase caused by large rolling mills of iron and steel metallurgical enterprises, on the basis of the rolling mill power supply system, dynamic reactive power compensation technology is introduced in the high voltage power distribution of Ma Steel's medium profile production line. The application in the grid, and through engineering examples, it is proved that the hybrid compensation of static var generator SVG and passive filter device FC can effectively eliminate the negative impact of impact loads such as metallurgical rolling mills on the grid, and achieve the expected filtering compensation effect and energy saving. At the same time, it provides stable and reliable power resources for the power grid, so that all indicators of the power grid meet the requirements of national standards, avoiding high fines from power supply companies, and bringing good economic and safety benefits to the steel plant. |
