This article researches the power system power flow calculation model under the environment of PC computers＇ calculation. By the network partitioning method based on the node-partition and the features of PC conputers＇ environment, it puts forward one kind of decomposition-coordination power flow parallel algorithm based on network mathematics segmentation. It divides the large-scale interconnected power system into several subnetworks, and by distributing the decomposition-coordination calculation between every subnetwork of every PC to gain the speedup. The result of power flow calculation test of this algorithm to IEEE standard system shows that this algorithm has the higher acceleration and calculation precision, which can be used in network computer environment.
