基于旁路技术的IEC 61968消息监管及交互测试方案

Bypass Technology Based Solution to Message Supervision and Exchange Test of IEC 61968

配电网业务量逐年扩展,相关应用系统的数据规模也在大幅提高,由于缺乏监管与检测手段而无法掌握已投运系统的信息交互情况,也未能分析面向业务的信息安全。利用网络旁路监听技术开展基于IEC 61968消息监管及其一致性测试研究,提出配电网信息交互在线一致性测试方法,支持生产控制大区与管理信息大区的业务数据汇总、整合与分析。通过交换机端口镜像旁路技术、IEC 61968消息对比技术实现对样本数据的采集和测试正确性判定,涵盖标准接口测试、交互场景测试及性能测试。整体方案面向配电网信息交互一致性测试的基本需求,结合项目研发的检测模块,验证测试样本数据是否符合IEC 61968标准的交互规定,最后给出测试结果。

The scale of data in correlative applications system is greatly improved along with the business volume extended in the distribution network each year.Since the lack of supervision and inspection method,it＇s difficult to get the information from the system which has already been in operation.In that case,it also cannot analyze the information security for business.Message flow supervision and conformance testing based on IEC 61968 series standard are studied through the bypass monitoring technology.The online conformance testing method of information interaction for distributed system is proposed to support the collection,integration and analysis of the business data for the large area of production control and information management.The use of switch port mirroring bypass and IEC 61968 message comparison technologies can realize the collection of sample data and the correctness judgment of test result,covering the standard interface test,interactive scene test and performance test.The overall plan aims to satisfy distribution network＇s basic requirements of the information interaction consistency test.Integrating with the detection module of project development,the consistence of the test sample data with IEC 61968 series standard is verified.Finally,the test result is given.
