摘　　要：为了探索建立配电快速仿真与模拟(DFSM)并行分布式计算环境的有效方法,将Agent和多Agent系统(MAS)的理论和方法应用于DFSM的研究;并以基于支路电流的配电网三相状态估计(DSE)为具体的研究对象,提出了Agent的八元素实现结构描述框架;详细阐述了配电网的分割方法和有偏序关系的配电子网状态估计迭代计算算法;设计并实现了基于MAS的DSE并行分布式计算环境(masDSE).算例分析表明:在实验系统中,masDSE可以使计算效率至少提高50%.Theories and methods of agent and multi-agent system（MAS） have been employed to study the effective way to establish distributed and parallel computing environment for distribution fast simulation and modeling（DFSM）.An eightelement computing framework based on agent technique has been presented for distribution three-phase state estimation（DSE）.Furthermore,distribution network division and iterative calculation algorithm for the distribution components with partial ordering relationship have been discussed.A parallel distributed computing algorithm for DSE based on MAS（masDSE）has also been presented.Case studies show that the proposed masDSE can reduce the time for distribution three-phase state estimation by at least 50%.
