Abstract:High-availability seamless redundancy ring network is one of the important links in outdoor installation protection of smart substation, and its performance directly affects the normal operation of relay protection devices. Aiming at the problem that ordinary network test equipment cannot perform ring network performance evaluation, a hardware test platform based on field programmable gate array and multi-core digital signal processor is designed according to the working mechanism of high-availability seamless redundancy ring network. The test method is determined by analyzing the principles of throughput, time delay, packet loss rate and error frame monitoring. The software is implemented following characteristics of each processor. The verification results show that the test platform designed in this paper can realize the performance evaluation of the ring network and ensure the reliable operation of the outdoor installation protection equipment of the smart substation.
