摘　　要：对于电网电压调节和潮流模型匹配等许多应用场合,可采用基于节点类型扩展的潮流计算方法。研究节点类型扩展潮流计算方法在电网电压调节和潮流模型匹配中的应用。首先,分析节点类型扩展潮流计算在节点电压调节问题中的可用性,并提出具体实现方法。然后,在分析已有潮流匹配方法不足的基础上,提出基于节点类型扩展潮流的多区域电网潮流匹配方法。最后,通过算例分析验证了节点类型扩展潮流算法在电压调节和多区域潮流匹配问题中的应用是有效的。For many application cases, such as voltage adjustment and power flow matching, methods based on bus-type extended load flow calculation can be effective. The application for bus-type extended load flow in voltage adjustment and network power flow matching was studied in this paper. A voltage adjustment method based on bus-type extended load flow was presented firstly. After that, the deficiency in traditional network power flow matching methods was well analyzed. Based on bus-type extended load flow, an efficient power flow matching method was proposed to match boundary power flow between the intemal and external power networks. Numerical tests showed that bus-type extended load flow method could be used to solve the problems of power flow adjustments efficiently.
