基于IEC61850的故障录波器服务端模型设计

Design of server model for fault recorder based on IEC61850

为了实现传统故障录波器兼容IEC61850通信协议,增加故障录波器通信方式,采用面向对象的建模方法,结合模块化设计思想,建立服务端模型,并对模型中的主要类进行设计。根据传统故障录波器采集模块的特点,选取IEC61850-8-1中的特定通信服务映射(SCSM)映射到报文制造规范(MMS)作为服务端模型通信协议。基于IEC61850通信协议的调度软件对该模型进行测试。测试结果表明,根据故障录波器监测对象的特点建立相应的逻辑节点,有利于服务端模型的设计与实现。

In order to make the traditional fault recorder compatible with IEC61850, the communication modes are added. By using the modeling technique of object-oriented programming, combining with the idea of module, the server model is established. According to the features of the data aequisitioning module of traditional fault recorder, the specific communication service mapping （SCSM） from IEC61850-8-1 is mapped to MMS, which is for the com- munication protocol of server model. The server model is tested by the scheduling software based on IEC61850 com munication protocol. Experimental results show that some suitable logical nodes are designed according to the fea tures of objects that are monitored by fault recorder, which are effective in the design of server model.
