摘要
随着调控中心的规模不断扩大,越来越多的数据被送至调度,用于调度智能告警的分析。上传数据的规模和冗余性会影响调度智能告警的效率和准确性,因此提出了一种基于拓扑的调控中心全局故障分析方法。电网故障后,由变电站自动生成准确、简洁、无冗余的故障分析报告,通过调度数据网上传至调度中心。调度中心利用电网的拓扑关系分析并生成全局故障分析报告,有助于更加准确地定位和处理电网故障。
With the expansion of the scale of the control center,more and more data are sent to the dispatch for the analysis of intelligent alarms. The scale and redundancy of the uploaded data will affect the efficiency and accuracy of intelligent alarm. Therefore,a global fault analysis method based on topology for control center is proposed. After power grid failure,the substation automatically generates accurate,concise and non-redundant fault analysis reports,which are sent to the dispatching center through the dispatching data network. The dispatching center uses the topological relationship of the power grid to analyze and generate the global fault analysis report,which is helpful to locate and deal with the power grid fault more accurately.
