摘要
为了解决当前智能变电站自动化系统内网络冗余存在的问题,提出了一种变电站内新型网络冗余的设备(双网冗余接口盒及双网冗余接口卡)软硬件实现方法,将变电站内部保护测控等装置通过双网冗余接口设备接入符合IEC62439-3规范的PRP/HSR网络实现新型双网冗余。采用FPGA+CPU的硬件构架,通过利用在FPGA设计出以太网通信控制MAC模块、PRP/HSR模块、存储控制模块、多路报文转发控制模块协同完成变电站系统内以太网报文冗余处理。试验证明,所研制的冗余设备满足电力系统保护装置对于速动性的要求,在智能变电站自动化系统内具有较好的实用性。
In order to solve the problem of network redundancy in substation automation systems, a new network redundancy device(double network redundant interface box and double network redundant interface card) is proposed to implement. The devices of the substation internal protection and control are connected to the PRP/HSR network which conform to IEC 62439-3 specification through the redundancy connection equipment. By using the hardware architecture of FPGA+CPU, the Ethernet communication control MAC module, PRP/HSR module, storage control module and multiple message forwarding control module are designed by using the Ethernet communication control module, and the redundant processing of Ethernet message in the substation system is completed. The test proves that the redundant equipment developed meets the requirements of the power system protection device for quick action, and has good practicability in smart substation automation systems.
