Overview of IED Data Application in Substation Ｒelaying Protection

摘要:

分析了智能变电站的 IED 装置特性，包括其通用的针对对象的建模方法和流程。概括总结出 IED 数据的应 用情况、应用方法和应用过程并对其数据的应用情况进行了分类，包含利用 IED 中的算法和数据进行故障区域判别 与故障定位、变电站事故自动分析。分析了特定 IED 装置的数据传递过程。最后，提出了以广域继电保护思想为基 础，建立 IED 数据在线自适应调整和自动有效分析的数据处理方案，并对其发展做出了展望。

Abstract:

The characteristics of IEDs in smart substation are analyzed，including its general object － oriented modeling methods and processes． The application of IED data is generally summarized and classified as well as the application method and process，which consists of carrying out faulty area identification，fault location and automatic analysis of substation events by using the algorithm and data in IEDs． Specific data transferring process of IED is also analyzed． In the end，on the basis of wide － area relaying protection，the IED data processing program with on － line adaptive adjustment and automatic analysis is proposed，and its future development is discussed．
