电网调度自动化实时信息分析与评估系统的研究

Research of real-time information analysis and assessment system for power network dispatching automation

介绍了一种分析电网调度自动化实时信息准确性的方案,通过对电厂、变电站的实时数据进行关联性分析,及时识别失准、异常信息,准确指引故障处理,并且采用信息准确率指标定量地评价出全网的自动化水平。该方案构建了一个基于CIM/XML模型的在线评估系统,不同型号的EMS系统的实时信息都能在该系统上进行分析与评估,因而具有推广性。实践结果证明了该方案的可行性和正确性。

A scheme to analyze the accuracy of real-time information for power network dispatching automation system is proposed in this paper, which identifies the incorrect telemetric data from power plant and substations based on the correlation analysis and guides troubleshooting. In addition, it justifies the automation level quantitatively by using the index of the accuracy rate of real-time information. Based on it, an on-line evaluation system based on CIM/XML is established, which is applicable for kinds of EMSs for real-time information analysis and assessment. The results show its feasibility and validity.
