数字化变电站IED互换性研究

The exchangeability study of digital substation intelligent electrical devices(IED)

受智能设备数据模型配置技术的限制,数字化变电站智能电子设备互换性还未能实现。在不改变IEC61850通信标准体系的前提下,提出了资源定义机制和基于需求激励的资源匹配机制,将IED的资源分为需求资源对象和生产资源对象。该定义机制在考虑IED拓扑关系的基础上,实现了变电站智能设备数据模型的自动配置,通过生产资源对象带语义的描述,屏蔽了IED内部的差异;通过该机制实现对IED资源的定义、激活、寻找、关联、交易和连接,以达到在数字化变电站内IED间互换性的实现。

Limited by the data model configuration technology of the smart device,IED exchangeability of digital substation has not been achieved.Following the IEC61850 communication system,this paper proposes resource definition mechanism and resource matching mechanism based on demand incentives,and divides the resource of IED into production resource object and demand resource object.The definition mechanism,considering the IED topology,achieves the automatic configuration of substation intelligent devices data model.Through the semantic description of production resource objects,the internal differences in IED are shielded.Through the mechanism,the resources of IED can achieve the definition,activation,search,association,transaction and connection,thus IED exchangeability in the digital substation is realized.
