IEC 61850标准中ACSI的原型设计与实现

Prototype Design and Realization of ACSI in IEC 61850 Standard

在IEC 61850标准中,抽象通信服务模型是标准的一个核心,文中提出了一种实现抽象通信服务的方法,并介绍了一个原型系统及其功能模块的构成设计。重点阐述了通过采用面向对象技术,将每一类服务抽象为一个类,通过类的属性与方法来描述服务的相关参数与状态机的转换,实现了抽象通信服务到类实例的转换。此外,通过类的继承与多态性分别简化了复杂服务的建立与多个服务实例的管理,并通过进程间的消息机制实现特殊通信服务映射(SCSM)。最后通过一个简单的实例验证了文中观点的可行性。

The abstract communication service model is one of the kernels of IEC 61850 standard. A method for realizing the abstract communication service is proposed. A prototype system and its infrastructure design are described. Based on obiectoriented technology, the abstract communication service is converted to a class instance. The attributes and methods of a class are used to reflect the service parameter and state-machine switch. Furthermore, the inheritable and polymorphism characteristics of the class can simplify the process of building complex service and the management of multi-class instances. Besides, the realization of specific communication service mapping （SCSM） is based on the messages between processes. Finally, a simple instance is used to verify the feasibility of the method proposed.
