【摘要】：为了解决变电站常规状态监测设备或非变电站设备与变电站内部IEC 61850标准监测系统无法直接通信的问题,文中提出了一种Modbus到IEC 61850-8-1协议转换的设计方法。采用面向对象技术对Modbus进行了数据建模;分析了IEC 61850及制造报文规范(MMS)信息模型和服务模型,根据分层语义对等原则建立了Modbus,IEC 61850以及MMS间信息及服务模型的映射关系;基于已建立映射模型完成了Modbus与IEC 61850-8-1转换模块的设计;最后以间隔控制器为例,建立了其相应的映射模型,采用MMS-EASE LITE等相关技术实现了协议转换模块的主要功能,完成了其相电流等测量数据的读写服务,验证了上述设计方法的正确性和可行性。
[Abstract]:In order to solve the problem that the normal state monitoring equipment of substation or non-substation equipment can not communicate directly with the standard monitoring system of IEC 61850 in substation, a design method of Modbus to IEC 61850-8-1 protocol conversion is presented in this paper. The data modeling of Modbus is carried out by using object-oriented technology, the information model and service model of IEC 61850 and Manufacturing message Specification (MMS) are analyzed, and the mapping relationship of information and service model between IEC 61850 and MMS is established according to the principle of hierarchical semantic peer-to-peer. Based on the established mapping model, the design of Modbus and IEC 61850-8-1 conversion module is completed. Finally, taking the interval controller as an example, the corresponding mapping model is established, and the main functions of the protocol conversion module are realized by using MMS-EASE divide and other related technologies. The reading and writing service of the measurement data such as phase current is completed, and the correctness and feasibility of the above design method are verified.
