摘要
进行配电网线损的计算方法有均方根电流法、平均电流法、等值电阻法、潮流前推回代法、电量法等,然而,由于配电网结构的复杂性、参数多样性和资料不完善以及缺乏实时监控设备,准确计算配电网线损一直是个难题。因此,根据不同情形,合理的选择适当的计算方法就具有一定的实际意义。首先对这些主要的计算方法进行介绍,然后根据实际算例对这些方法所求得的结果进行对比分析,得出各种算法所适用的情形。
There are lots of methods for distribution network loss calculation,such as the equation squared root method of currents,the average current method,equivalent resistance method,forward and backward substitution method of flow,coulometric method,and so on.However,it is difficult to calculate accurately the line loss because of the complexity of network structure and the imperfection of data information.Therefore,according to different circumstances,it is significant to select an appropriate method for line losses calculation.This paper first introduces the main calculation methods,and then uses different algorithms in the practical example.Finally the results are analyzed,and some conclusions are reached.
