HSR在第三代智能站中的实现技术
Implementation technology of HSR in the third generation intelligent station
The existing network redundancy schemes of smart substation mostly adopt A/B network scheme. The underlying links are deeply coupled with service protocols, which makes it difficult to use standard hardware modules for general processing. It also brings various problems such as heavy load, high cost and dependence of network reliability on core switch equipment. In IEC62439-3 standard, PRP and HSR are provided to solve these problems effectively in star network and ring network structure respectively. This paper focuses on HSR standard and implementation technology, and studies the implementation technology of HSR networking based on IEC62439-3 standard for the local module of the third generation intelligent substation. It mainly includes the interconnection technology based on software bottom driver and FPGA interaction, the implementation technology of IEEE 1588 pair-time standard in HSR loop network, and time-sensitive data synchronization scheme for HSR ring network based on delay measurement technology. This technology provides technical support for the implementation of high availability ring network of local module.
