嵌入式网络单片机及其在变电站自动化通信中的应用

随着变电站自动化技术从中、低压变电站系统向高压、超高压变电站系统发展,对变电站自动化通信网提出了更高的技术要求,从而使嵌入式系统在变电站自动化通信中倍受关注。介绍了在变电站自动化系统中实现嵌入式以太网的关键技术,指出采用由Ubicom公司的IP2022以太网协议转换芯片构成的嵌入式网络单片机是变电站自动化通信网的最佳配置方案,并对这种嵌入式网络单片机的软、硬件,及其在变电站自动化通信中的应用模式进行了深入的分析,认为嵌入式以太网是今后变电站通信网的热点和发展方向。

Embedded network single-chip computers applied in substation automation communication

With the development of the substation automation system from MV/LV to HV/EHV, higher technical requirements have been set on substation automation communication network, and the embedded system, which is applied in substation automatic communication, has attracted most attention. This paper describes the key technique for realizing embedded Ethernet in substation automation system, indicating that the optimal configuration scheme for substation automation communication network is to use embedded network single-chip computers based on Ubicom's IP2022 Ethernet protocol conversion chip. With a profound analysis of the software, hardware of the embedded network single-chip computer as well as its application mode in substation automatic communication, it is concluded that the embedded Ethernet will be a hot spot and development trend for substation communication network in the future.
