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 carry out the ultimate stress test and network load test of IEC61850 client and to simulate the IED communication behavior at the same time, a server-side simulation system based on IEC61850 and its implementation method are proposed. The system injects information sources with substation configuration description (SCD) files, virtualizes multiple IEDs, assigns a data generator to each model data object, and provides a data change editing interface that generates a sequence of states through the data generator and feeds back in real time IEC61850 database. By IEC61850 communication with the station-level equipment to achieve the whole station IED analog rehearsal, which can be exposed in advance substation interoperability problems, help to understand in detail the substation network communication load situation. The system has strong operability, high efficiency and flexible configuration, which can greatly shorten the IEC61850 engineering debugging cycle and promote IEC61850 engineering implementation and promotion.
