摘　　要：提出发输配全局潮流计算这一新课题，它以全局电力系统为研究对象，能计算出一体化的全局电力系统状态，弥补了传统潮流计算中发输电系统和配电系统完全独立进行的局限性，可满足全局控制决策的需要。建立了数学模型，构造了全局潮流主从分裂法，自然地将规模庞大的全局潮流问题分解成发输电潮流和一系列小规模的配电馈线潮流子问题，发输电和配电可用不同的潮流算法，满足了全局潮流在线分布式计算的要求。In this paper, a new topic of Global Power Flow Calculation(GPFC) is presented. By the GPFC, the united global power system state can be calculated, and the limitations of the traditional method, where the transmission network and distribution network are isolated, are overcome. In order to solve the difficult large scale problem of GPFC, the mathematical model and a new master slave splitting based method which fits for GPFC are proposed. In the new method, the large scale problem of GPFC is divided into a transmission power flow and lots of small scale distribution feeder power flows. Different iterative method can be used for solving transmission sub problem and distributed sub problems.
