EMS与DMS间数据交互的数据传输与安全控制操作方法研究

随着电力系统的发展,尤其受城乡电网建设与改造的影响,对配网管理系统(DMS)改善电能质量提出新的要求。能量管理系统(EMS)与配网管理系统间的数据交互越来越多,DMS通过EMS进行控制操作的需求越来越急切。基于IEC104规约在EMS与DMS间的扩展应用,并通过遥控信息冗余校验的概念,给出遥控信息冗余校验判断策略,提出了EMS与DMS间数据交互和安全遥控操作的方法,实现EMS向DMS转发遥测、遥信数据。华东地区的应用情况验证了该方法的可行性和实用性。

Research on data transmission and security control operation method of data interaction between EMS and DMS

With the development of the power grid, and especially influenced by the construction and transformation of power grid in urban and rural areas, it puts forward new requirements for power quality improvement in Distribution Network Management System (DMS). So the data exchanges between Energy Management System (EMS) and DMS are increasing, and the function of sending control signals between DMS and EMS is also becoming more and more urgent. Based on the extended application research of IEC104 protocol between DMS and EMS, the function of transmitting the remote measuring data and remote communication data to DMS via EMS is realized. Using the concept of remote control information redundancy check, the judgement strategy of remote control information redundancy check is given. Then, the method of data interaction and safety remote control between EMS and DMS is proposed. The application in East China has proved that the method is feasible and practical.
