基于IEC61850标准的电力参数监控模型设计

Design of Monitoring Model for Power Parameter Based on IEC61850 Protocol

IEC61850是电力参数监控系统自动化功能的服务标准而非功能标准,针对变电站内IED之间的互操作性差、难以实现信息交互的问题,探讨了基于IEC61850标准的电力参数监控模型设计。分析了IEC61850标准的技术内涵、技术特征与IED信息化过程,讨论了面向对象的信息与设备模型,研究了设备管理模块的构成与电力参数监控系统数据模型设计。研究表明,该监控模型不仅可满足不同自动化功能对通信过程、通信性能和可靠性的不同要求,而且有利于采用最新通信技术实现对电力参数的监控,为系统拓展预留了广阔的空间。

IEC61850 protocol is the service standard of automation function in power parameter monitoring system,and not the function standard,aimed at that it is poor in interoperability among intelligent electronic devices（IED） in the substation and difficult to realize the information interaction,the paper explored the design of power parameter monitoring model.It analyzed the technology connotation,technical feature and informatization process of intelligent electronic devices,discussed the object oriented information model,built the device model,researched the constitution of device management module,and designed the data model of power parameter monitoring system based on IEC61850 protocol.The research shows that the monitoring model not only can satisfy the different demand of different automation function in process and performance as well as reliability of communication,but also it is propitious to adopt up to date communication technology to realize the monitoring for power parameter,and it obligates a wide space for system prolongation.
