基于IEC 61850的数字化变电站服务器端模拟系统及实现

Digital Substation Server Simulation System Based on IEC 61850

为了更好地对IEC61850客户端进行极限压力测试及网络负荷测试,同时对智能电子设备(IED)通信行为进行模拟,提出一种基于IEC61850的服务器端模拟系统及实现方法。系统以变电站配置描述(SCD)文件为信息源注入,虚拟出多个IED,为每个模型数据对象分配一个数据生成器,并提供数据变化编辑接口,通过数据生成器产生状态序列,实时反馈到IEC61850数据库。通过IEC61850与站控层设备进行通信,实现了全站IED的模拟预演,从而可提前暴露变电站内的互操作问题,有利于详细了解变电站网络的通信负荷情况。该系统具有可操作性强、效率高、配置灵活的特点,可大大缩短IEC61850的工程调试周期,促进IEC61850工程化的实施和推广。

In order to better carry out the critical test and network loads test for IEC 61850client and simulate the communication behavior of intelligent electronic devices（IEDs）as well,a server simulation system and its implementation method based on IEC 61850is put forward.The substation configuration description（SCD）file is treated as information source input of the system.And multiple IEDs are simulated.The system can assign a data generator to each model data object, provide data change editing interface,and produce the status sequence with the data generator,then real-time feed back the status to IEC 61850database.Through IEC 61850protocol communication with station control layer,the simulation preview of all IEDs in the substation is achieved.By early exposure to substation interoperability problems,it is in favor of fully understanding the situation of substation network communication loads.With enhanced workable,high efficient,flexible configuration features,the debugging cycle of IEC 61850related engineering can be significantly shortened,thus it will greatly facilitate implementation and promotion of IEC 61850related engineering.
