| 摘 要： | 针对炼钢电弧炉电弧电流难测量的问题,在分析了变压器运行机理的基础上,通过建立电弧电流与电炉变压器一次侧三相负载电流、三相空载电流及三相功率因数之间的数学模型,提出了一种间接测量电弧电流的新方法.考虑到实际运行中变压器负载电流比空载电流大得多,在忽略变压器空载电流的前提下,导出了电弧电流与变压器一次侧三相电流、三相电压及三相总有功功率之间的简化模型.理论分析和计算机仿真验证了所提方法的有效性,为电弧电流的测量提供了新的途径. |

| Abstract: | To solve the problem that the arc current of electric arc furnace(EAF) is difficult to measure,a new method is proposed to estimate the EAF arc current by developing a relational data model between the arc current,three-phase power factors and primary three-phase load/no-load current of EAF transformer of which the operating principle is discussed.In view of that the load current is much higher than the no-load one during the actual transformer operation,the model is simplified to describe the relation betw... |
