Low Voltage Distribution Network Line Loss Calculation Based on The Theory of Three-phase Unbalanced Load

摘要：

　　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 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.In this paper,combined with the structure and power consumption characteristics of the low pressure platform,a regional representative area is selected for the research.The regional and seasonal loads of the selected stations are analysed.Finally,a stage area of theoretical line loss calculation that takes into account the three-phase unbalanced load.
