摘要
变电站通信网络和系统系列标准IEC61850目标在于提高产品间的互操作性和兼容性,建立无缝的通信体系,基于这一标准的嵌入式以太网技术成为变电站自动化系统发展的趋势。提出了基于Rabbit2000+DynamicC的嵌入式以太网在装置上实现方案,给出了基于嵌入式以太网的变电站通信网络结构,Rabbit2000的系统结构,以及该方案的硬件系统和软件设计。该方案满足了IEC61850对通信接口的要求和装置实时多任务通信的特点,同时提出了具有兼容性的嵌入式规约转换的思想。实际运行表明该方案可行。
The purpose of IEC 61850,the communication network standard of SAS（Substation Automation System）,is to enhance the interoperation and compatibility among SAS products for building a seamless communication system. The embedded Ethernet technology based on this standard is widely applied in SAS. The implementation of embedded Ethernet in devices based on Rabbit ＋ Dynamic C is introduced. The embedded Ethernet-based substation communication network structure and Rabbit 2000 structure are provided,as well as the system hardware and software designs. This scheme satisfies the requirements of both IEC 61850 communication interface and real-time multitask communication. Moreover,a new compatible method on embedded protocol conversion is also proposed. Practice shows that the proposed scheme is feasible.
