摘要
现有智能变电站通信模型主要依据国际电工委员会发布的MMS通信基本数据模型和国网发布的“SGCC MODEL:2012”基本数据模型来创建,其数据模型主要面向继电保护设计,并不完全适用于测控等其他装置,若均使用上述基本模型来建立特殊变量的通信模型,会导致通信报文大幅增长,加重服务器负荷,并且对图像等可变数据长度建模完全无法实行。文中创新性地引入BitString可变长度数据类型作为基本数据模型,并使用这种基本数据类型对特殊类型的通信数据进行建模设计,然后对扩展后通信模型进行了测试。结果表明,BitString可以建立一种可变长度模型数据元,从而有效缩减了报文结构大小,增加了面对复杂通信数据结构尤其是可变长度通信数据结构体建模的灵活性。
The existing smart substation communication model is mainly based on the MMS communication basic data model released by the International Electrotechnical Commission and the“SGCC MODEL:2012”basic data model released by the State Grid.The data model is mainly for the design of relay protection and is not fully applicable for other devices,such as measurement and control.If the above basic model is used to establish a communication model with special variables,it will cause a substantial increase in communication messages,increase the load of the server,and make it impossible to implement variable data length modeling such as images.This paper innovatively introduces the BitString variable-length data type as the basic data model,and uses this basic data type to model and design special types of communication data,and then tests the expanded communication model.The results show that BitString can establish a variable-length model data element,thereby effectively reducing the size of the message structure and increasing the flexibility of modeling complex communication data structures,especially variable-length communication data structures.
