摘　　要：为解决电力调度运行镜像系统中异构模型数据丢失问题,研究了异构模型数据映射的技术特性,分析了模型映射中遥测遥信数据缺失的原因。针对遥信数据缺失、母线中单一支路遥测缺失和环路中单个支路遥测缺失等情况,提出了拓扑搜索推导、节点功率推导和支路环路推导等基于逻辑推导的异构模型数据补齐方法;针对节点或环路中多支路遥测缺失等复杂情况,提出了基于独立环路功率方程和节点功率方程组成的多量测方程组,应用加权最小绝对值进行估计的数据补齐方法。该方法已经在南方电网调度运行仿真镜像系统中得到了应用。In order to solve the problem of signal missing in heterogeneous model in power system dispatching and operation simulation mirror system, the technical characteristics of data mapping of the heterogeneous model are researched in this paper. And the reason for remote measurement and remote signal missing during the data mapping is also analyzed. Aiming at the sitations of remote signal missing, remote measurement missing for a single branch of a bus node or power grid loop, the data complement methods based on logic derivation including network topology searching, nodal power balance equations and branch loop power equations are addressed. Aiming at the complex siuation of multi-branch data missing, a new data complement method of the weighted least absolute value state estimation based on the independent branch loop power equations and bus node balance equations is proposed. This method has already been applied to the power system dispatching and operation simulation mirror system of CSG.
