摘要:
目的：为实现直流牵引供电系统的信息快速共享，提高供电系统的可靠性，增强装置间的互操作性，在传统方案基础上提出了基于GOOSE（面向通用对象的变电站事件）通信技术的直流牵引供电系统跨所域网络化保护方案。方法：基于光纤点对点的间隔层组网模式，从系统可靠性、工程应用便捷性考虑，通过 GOOSE通信技术替代传统的硬接线实现变电所间的保护联跳、闭锁信息的传递。结果及结论：与传统方案相比，本方案在保证原有保护功能的基础上，扩展了直流区间网络化保护功能。测试结果表明，本方案能实现可靠的保护联跳、闭锁，具有较高的可靠性，为直流牵引供电系统跨所域信息传输提供一个新的选择。

Objective: To achieve rapid information sharing of DC traction power supply system, as well as improving reliability of the system and enhancing the interoperability between devices, a crosssubstation networking protection scheme for DC traction power supply system based on GOOSE (generic object oriented substation event) communication is proposed, building upon the conventional approaches. Method: Based on a fiberoptic pointtopoint interlayer networking model, considering system reliability and engineering application convenience, the GOOSE communication technology is employed to replace conventional hardwired connections for the transmission of protection intertripping and interlocking information between substations. Result & Conclusion: Compared to conventional approaches, this scheme extends the functionality of networking protection in DC interval while ensuring the preservation of existing protection features. Test results demonstrate that this scheme achieves reliable protection interlocking and intertripping, featuring higher reliability. It provides a new choice for crosssubstation information transmission in DC traction power supply system.
