摘要
针对传统配电网线损计算方法的不足 ,在负荷曲线形状系数的确定、配变铜损计算、对配电网小 (或多 )电源的处理、支路和配变的线损率计算等方面对传统方法进行了改进 ;并通过算例将改进方法、传统方法及牛顿潮流法进行了比较分析 。
After analyzing the shortcomings of the current line loss calculation of distribution network, this paper presents some improved proposals on the determination of load shape coefficient, the loss calculation of transformer winding resistance and the treatment of small (or multiple) power sources in distribution network. As a supplement, this paper also brings forward the loss rate calculation method for branch and transformer. The correctness and practicability of the improved method is verified by the comparison with the current method and Newton method.
