摘　　要：实现智能电子设备(IED)间互操作是变电站通信网络和系统系列标准IEC 61850的重要目标,模型设计是实现这一目标的重要步骤。从互操作性支持条件分析出发,给出了IED模型通用设计方法,讨论了间隔层IED的模型实现。间隔层IED的信息模型以数据结构的形式实现。从互操作性角度分析了已有数据逻辑结构的优缺点,提出了抽象通信服务接口(ACSI)-功能约束(FC)结构,把FC引入数据结构且真实反映了信息模型的对象层次,从而更好地支持互操作性。另外,提出了基于二叉树形式的二叉和三叉链表数据存储结构,通过例子验证了这2种结构的数据查找和遍历的便利性,并给出了ACSI-FC结构在二叉或三叉链表存储结构下的FC过滤方法。Interoperability is the most important objective of IEC 61850. Model design and realization are critical steps to achieve the objective. Based on an analysis of interoperability support, a universal design method of IED model is given, and problems in realization of bay level IED model are discussed. Bay level IED is an embedded system, whose information models are realized in the form of data structures. The advantages and disadvantages of several data structures considering interoperability are examined. On this basis, a new data structure named ASCI-FC data structure is designed, in which functional constraints （FCs） are included while the hierarchical structure of information model is retained, thus better supporting interoperability. Data storage structures making use of the binary or ternary chain llst are given, Examples prove their advantages at object locating and data traversing. A FC filtering method for ASCI-FC data structure stored in binary or ternary chain lists is also given to show the advantage of this data structure.
