基于MAS的变电站信息一体化嵌入式平台设计

由于缺乏统一设计和缺少有效的信息整合平台,变电站内"信息孤岛"现象及系统的异构化程度日趋加重,信息的有效利用受到很大限制。按照IEC61850标准及面向对象技术,设计一种变电站信息一体化嵌入式平台,给出兼容变电站遗留设备及IEC61850标准设备的分布式接入方案,并提出基于多智能体系统(MAS)的软件体系架构。多个智能体之间通过分布式的灵活组态方式及发布/订阅机制,较好地兼顾了嵌入式系统的稳定性和性能的平衡。所述方法具有较高的敏捷性和可扩展性,为数字化变电站工作的开展和全面向IEC61850标准平稳过渡提供了一种新的可行途径。

Design of Embedded Platform for Substation Data Integration Based on Multi-agent System

With the development of technology in substation automation,more and more information isolated islands and new application systems owned heterogeneous data have emerged.However,some information of these application systems cannot be utilized sufficiently by power enterprise management systems because there is neither design as a whole nor applied integrated platform of substation information.An embedded platform for substation data integration(EPSDI)and a compatible interface scheme for both legacy intelligent electronic devices(IEDs)and standard IEDs based on IEC 61850 are proposed.The software architecture based on multi-agent system(MAS)is realized.And the balance between the stability and the performance can be achieved through the agile distribution configuration and publish/subscribe mechanism among agents.The method can bring a new feasible approach to propelling substation smooth digitalization based on IEC 61850,due to its good application and expandability.
