基于IEC 61850的就地化保护智能管理单元互操作

IEC-61850-based localized protection intelligent management unit interoperate problem analysis and treatment

就地化保护智能管理单元是伴随就地化保护装置出现的新产物,智能管理单元与就地化保护采用具备互操作性的IEC 61850协议通信。在互操作过程中,智能管理单元的功能受到了保护装置建模和实现差异性的影响,特别是在字符串类型数据的查看和定值互操作上。对这2个问题发生的原因进行了分析并提出了智能管理单元互操作的解决方案,在模拟试验环境和真实投运环境里验证了方案的正确性和可靠性。

Localized protection intelligent management unit generated with localized protection device. Intelligent management unit and localized protection adopted IEC 61850 protocol. During interoperation,function of intelligent management unit was influenced by protection device model and differences,especially the interoperation of reviewing and valuing of string type data.After analyzing these two problems,solution was provided accordingly. Correctness and reliability was proved in simulation and practical environment.
