IEC61850到IEC60870-5-101/104映射的关键技术研究

变电站通信系统若采用基于IEC61850通信结构的通信信息模型,必然要解决新系统兼容老设备的问题。目前的变电站通信中采用IEC60870-5-101/104的老设备还很多,而从IEC60870标准过渡到IEC61850是一个渐进的过程,在很长时间内使用IEC60870-5-103/104标准的老设备也会大量存在,必须保证使用IEC60870通信标准的装置在通信上与新系统相互兼容。比较了IEC61850与IEC60870标准两种不同标准体系的特点,依据变电站通信功能的特点和IEC61850的映射原则,提出了将IEC61850的数据模型和控制模型映射到104规约的映射方法和思路,将采用101/104规约的老装置纳入新的变电站通信体系。以使采用两种不同通信标准的装置可以实现互联和互通。

Research of maping IEC61850 to IEC60870-5-101/104

The application of IEC61850 in substation communication can enhance the automation level of substation management.However,to solve the problem of compatibility between device applying IEC61850 protocol and device applying 101/104 protocol,communication information model in substation communication system should be considered.There are many devices applying IEC60870-5-101/104 in substation at present.How to make these devices compatible with new standard needs to be solved.This paper compares the IEC61850 with IEC60870,provides the methods of mapping the communication model of IEC61850 to IEC60870-5-101/104.This mapping makes the devices applying the two different standards connect and exchange information with each other,and is a reference to IEC60870-5-103 based on the network map to IEC61850.
