摘　　要：针对小电源直接接入配网的特点,对配网线损的计算方法进行研究,结合等效电阻模型,对当前处理配电网小电源问题的等效容量法进行改进。改进方法考虑了配电网馈线和小电源运行方式的变化以及一日内可能的馈线潮流的双向流动。最后用生产实例验证了改进方法的准确性。In view of the character of the distribution network which was directly connected with small source, an improved method of equivalent capacity was proposed combining with the equivalent resistance model after analyzing several line loss calculation methods. This proposed method considered the complex situations of operating nodes changing in power distribution network on the representation day, and the situations including the two-way flow of power system tidal current between small source supply and distribution network. Practical examples were used to verify the improved method.
