为解决钢铁冶金企业大型轧钢机造成系统电压波动、功率因数降低和线路损耗增加等电能质量问题，在轧机供电系统的基础上，介绍了动态无功补偿技术在马钢中型材生产线高压配电网中的应用，并通过工程实例证明静止无功发生器SVG和无源滤波装置FC的混合补偿能够有效地消除冶金轧机等冲击性负荷对电网的不利影响，达到预期的滤波补偿效果和节能降耗的目的，同时，为电网提供了稳定可靠的电力资源，使电网的各项指标均达到国家标准要求，避免了供电公司的高额罚款，给钢厂带来了良好的经济安全效益。

Research and Application of Hybrid Reactive Power Compensation Device in Steel Rolling Production Line

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.
