摘　　要：在线数据模型及电网参数是电网调度一体化运行计算分析的基础。考虑多源数据的特征,提出了基于多源数据的在线数据评估方法。采用动态智能映射策略方法进行在线数据模型评估,进而利用模型评估的结论结合SCADA/EMS的数据给出电网参数评估方法;最后利用电力系统高级计算的相关知识对在线数据进行调整。实际算例证明该方法能够对在线数据进行全面的评估及校核,并具有较高的计算精度,能为智能电网技术支持系统在线数据实用化分析提供一种可行的方法。Online data model and the power network parameter are the foundation of the integration analysis of the grid dispatching operation. Considering the characteristics of multi-source data, this paper proposes an online data evaluation method based on the multi-source data. This method adopted dynamic intelligent mapping strategy to evaluate the online data model, then combined the evaluation result with SCADA/EMS data to get the network parameter evaluation method. Finally it adjusted the online data by using the relevant knowledge of the electric power system advanced calculation. Practical examples prove that this method is capable of conducting a comprehensive assessment and checking on online data and has higher calculation accuracy. It can provide a feasible method for the online data＇s practical analysis of the intelligent power technology support system.
