在变电站建立符合IEC 61850和制造报文规范(MMS)的子站系统,将使调度端对变电站的数据获取面向对象、面向目标应用和面向点对点通信;其中,至关重要的是如何针对应用需求和接入的实设备建立相应模型。文中经分析认为,应该使用比开放式系统集成(OSI)更具普遍价值的虚拟制造设备(VMD)与对象映射接口(OMI)的设计方法,同时要强调符合 ISO设计和 IEC 61850下对实设备原理的理解、抽象、映射。文中以电网继电保护故障信息系统的子站系统为例,从其主站需求和子站所集成的变电站内保护装置和录波器的原理出发,描述了 IEC 61850在子站的建模过程,包括信息建模与服务(通信)建模,其方法对于现实中实施 IEC 61850具有普遍的参考价值。
The establishment of a substation system in accordance with IEC 61850 and the Manufacturing Message Specification (MMS) at the substation will enable dispatchers to obtain object-oriented, object-oriented applications and point-to-point communications for substation data; the crucial one is how to address the application requirements And access to real equipment to establish the appropriate model. According to the analysis, the design method of VMD and OMI, which is more common than Open Systems Integration (OSI), should be used. At the same time, Understand the principle, abstract, mapping. Taking substation system of grid fault protection information system as an example, this paper describes the IEC 61850 substation modeling process based on the requirements of its main station and the principle of protection devices and oscillographs integrated in substations. Including information modeling and service (communication) modeling, the method for the implementation of the IEC 61850 in practice has universal reference value.
