| 摘 要： | 电弧炉对供电系统造成的电能质量问题主要是引起供电系统电压波动。建立了用于电压波动研究的电弧模型,新模型是将确定性电弧模型与弧长变化规则相结合来模拟电弧炉负荷的非线性和随机性。其中确定性电弧模型以能量守恒定律为基础,用非线性微分方程描述电弧电导、电流和弧长之间的函数关系;电弧弧长变化规则是在理想弧长基础上叠加带通白噪声。在Simulink环境下,将新的电弧数学模型作为一个等效电压源接入电弧炉供电系统进行仿真。通过与现场实测数据进行对比,证明新模型可用于仿真研究电弧炉引起的供电系统电压波动问题。

| Abstract: | The affect of electric arc furnace on power quality deterioration of power supply system appears as voltage fluctuation.An electric arc model for the research on voltage fluctuation is built,which simulates nonlinearity and randomness of arc furnace load by combining definitive electric arc model with variation rule of the electric arc length.The definitive electric arc model is based on the law of conservation of energy,and the functional relation among conductance of electric arc,current and the electric ... |
