摘要
加热炉在运行中,会产生大量谐波、负序,产生无功冲击并导致电压波动和闪变,冶炼功率因数低等电能质量问题,降低供电系统的可靠性,并危害其他设备安全。本文从分析莱钢供电系统及电网情况入手,结合现场设备实际运行参数,系统进行静止无功补偿装置各参量参数计算,各次滤波器设计选型,并初步介绍了SVC静止无功补偿计算机控制系统的设计组成、具备的技术特点及应用效果。
In the operation of the Heating furnace,can produce a large number of harmonics,negative sequence,shock of reactive power and voltage fluctuation and flicker,smelting low power factor of power quality problems,reduce the reliability of power supply system,and endanger the safety of other equipment.This article obtains from the analysis of power supply system and power grid in lai steel case,combined the actual operation parameters,equipment system for static reactive compensation device of each parameter calculation,parameter all filter design selection,and introduces the SVC static reactive power compensation of computer control system design,the technical characteristics and application effect.
