基于设备网络服务框架的微网监控构架与自适应服务方法

摘要

针对传统的基于客户机/服务器(C/S)模式的微网监控系统缺乏对动态网络的适应性支持和Multi-Agent 安全性不足的问题，提出了基于新一代网络中间件———设备网络服务框架(DPWS)的微网分布式监控架构和自适应服务方法。根据微网的特点和要求建立了微网系统的网络监控模型。利用 DPWS 的“即插即用”机制解决了设备入网的自动识别、自动入网问题，通过服务调用和事件订阅服务实现了对目标数据和状态的实时观测，运用 HTTPS 方法确保了数据传输的安全性和完整性。软件开发与仿真证明该系统具有良好的动态性和自适应能力，能够实现对微网监控设备的智能化管理。%In view of the traditional microgrid monitoring system based on the client/server (C/S) mode lacking adaptive support for the dynamic network,plus the problem of insufficient multi-agent safety,a kind of distributed monitoring network for the microgird based on a new network middleware-device profile of web service (DPWS) and the self-adaptive service method are proposed.A network monitoring model of microgrid system is developed according to the characteristics and requirements of the microgrid.The plug-and-play mechanism is used to solve the problem of auto-recognition and auto-netting of equipment.Through service invoking and event subscription,real-time observation of the target data and status is achieved. HTTPS ensures the security and integrity of data transmission.It is proved by software development and simulation that this system is capable of realizing intelligent management of the monitoring devices of the microgrid with its good dynamic performance and adaptive ability.
