摘要
在分析了现有配电网线损计算方法优缺点的基础上,提出了一种改进型配电网理论线损计算方法。该方法充分利用可获取的配电网运行参数,利用功率平衡的原理来计算配电网的线损,并以15节点10 kV配电网的线损计算为例,验证了该方法的有效性。该方法采用的配电网运行参数数据量越大,计算精度越高,可以广泛应用于各供电公司、大型工矿企业和高等院校的理论线损计算与节电指标考核。
This paper puts forward a modified method of line-loss calculation in the medium voltage distribution system based on an analysis of advantages and disadvantages of the existing line-loss calculation methods for the distribution system. This method makes full use of available operating parameters of the distribution system by using the power balance principle to calculate the line-losses of distribution system, a line-loss calculation example for a 10kV distribution system with 15 nodes is presented, and the results verify the effectiveness of the method. The precision of this method depends on the amount of the run parameters of the distribution system. It can be applied to the line-loss management and the power-saving assessment of all power supplying enterprises, large industrial and mining enterprises and universities.
