文章介绍了一种数字化变电站间隔层与变电站层之间的嵌入式网络接口的设计。该设计遵循IEC61850标准,以ARM7微处理器LPC2210和实时操作系统uCOS-Ⅱ为开发平台,通过控制以太网控制器RTL8019AS来实现。该设计还可应用到过程层,实现过程层、间隔层、变电站层三者之间的通信,加快了变电站的自动化。
The article introduces the design of an embedded network interface between a digital substation compartment and a substation layer. The design complies with IEC61850 standard, ARM7 microprocessor LPC2210 and real-time operating system uCOS-Ⅱ as the development platform, through the control of Ethernet controller RTL8019AS to achieve. The design can also be applied to the process layer to achieve the communication between the process layer, the spacer layer and the substation layer, accelerating the automation of the substation.
