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。
In the IEC 61850 standard, the abstract communication service model is a core of the standard. In this paper, a method of implementing abstract communication service is proposed. The design of a prototype system and its functional modules is also introduced. This paper focuses on the abstract of each class of service by abstracting it into a class by using object-oriented technology, describing the service related parameters and the state machine’s transformation through the properties and methods of the class, and implementing the transformation from abstract communication service to class instance. In addition, the establishment of complex services and the management of multiple service instances are simplified by class inheritance and polymorphism, respectively, and the special communication service mapping (SCSM) is implemented through the message mechanism between processes. Finally, through a simple example to verify the feasibility of the point of view.
