摘要：

As more and more users require the microprocessor protection device has Ethernet interface based on IEC61850, a newly developed relay protection equipment based on DSP with Ethernet communication interface is introduced. The hardware circuit design, drive program and TCP/IP protocols are developed in detail to explain how to realize the Ethernet communication. We use DSP TMS320VC33 as the hardware platform and RTL8019AS as the Ethernet control chip. RTL8019AS is connected with DSP by (Complex Programmable Logic Device) CPLD. The Integral layer model for Ethernet communication is a seven layers model based on IEC61850. The transport layer uses UDP protocol to transport data, as it is faster and more efficient. It can finish the Ethernet communication task and switch to other tasks by sending out and releasing signals to DSP. Experiment shows that it can satisfy 110kV line and below voltage relay protection's technology requirement to Ethernet communication successfully.
