| 摘 要： | 低压配电网线损计算作为线损治理工作开展的基础,有必要对其进行深入研究。但是随着非线性负荷的不断增加,谐波对线损的影响也日益严重,而传统的等值电阻法计算低压配电网线损中,没有考虑到非线性负荷情况下集肤效应对线路损耗的影响。因此,首先分析集肤效应对导线电阻的影响,对考虑集肤效应的等值电阻法进行了详细推导,并以某台区为例验证了考虑集肤效应的等值电阻法计算线损的正确性。 |
| 关 键 词： | 低压配电网 线损 等值电阻法 集肤效应 谐波 |

| Abstract: | As the foundation of line loss management,it is necessary to conduct deep research on the line loss of low-voltage distribution network.With the increase of nonlinear load,the effect of harmonics on line loss is increasingly severe.However,with the traditional equivalent resistance calculating method,the impact of skin effect on line loss caused by nonlinear load has not been considered.In this paper,the impact caused by the skin effect is illustrated firstly,then,the equivalent resistance method upon the skin effect is derived.Finally,a line loss calculation example for a low voltage transformer area is presented,and the results verify the effectiveness of the method. |
| Keywords: | low voltage distribution network line loss equivalent resistance method skin effect harmonic |
