对多电源配电网三相潮流计算的探讨

摘要

To distribution system, this paper puts forward a new three-phase load flow calculation base on back/forward sweep and superposition theory. At first, the method makes use of topology technology to disposed of distribution system, then calculates circulation current of each other power point, separately. In succession, the every power point is equiva- lent to only one point in distribution system, then calculates branch current by use of back/forward sweep and superposition theory in whole system and voltage. At last the whole distribution system three-phase load flow is found.%针对配电网络的特点,提出利用叠加原理求解多电源配电网三相潮流的一种新的算法。该方法首先利用拓扑技术对配电网进行处理,分别计算各电源点之间的循环电流,然后把各电源等效处理为一个点,接下来运用前推回推法和叠加原理求出整个网络的支路电流,再回推整个网络的电压,最终计算出整个网络的三相潮流。
