摘要(Abstract):
针对农村公用配电变压器低压台区线路的运行特点,提出了以三相负荷不平衡损失系数为主要因素的低压台区线路线损理论计算的数学模型和等值电阻计算方法,相对于传统粗估计算法而言,大大提高了低压台区线路线损理论计算的精度。
Based on the operation characteristics of the rural public low-voltage distribution transformer areas,this paper puts forward the theoretical calculation math model and the equivalent resistance calculation method of line loss in low-voltage transformer areas,in which the unbalanced three-phase load loss coefficient is considered as the main factor.Compared to the traditional estimation method,it greatly improves the accuracy of theoretical calculation of the line loss in these areas.
