基于知识的多源异构信息一体化研究

RESEARCH ON KNOWLEDGE BASED INTEGRATION OF MULTISOURCE HETEROGENEOUS INFORMATION

为满足电网调度系统协同应用开发的需要,提出了一个多源异构信息集成框架。该集成框架借鉴CORBA规范, 采用面向对象封装技术和基于知识的自动映射机制,解决了不同应用对象系统的集成问题。并结合河南电网实际,详细分析了包括实现图形一体化、电网结构参数等数据信息资源共享的集成原理和实现技术,实现了DTS与EMS/SCADA系统的一体化,达到了DTS与异构系统的高度集成。该集成框架具有开放、通用、自动化程度高的特点,为异构型系统的一体化仿真建模提供了新的途径。

To meet the need of cooperative application development of power system dispatching system, a framework to integrate multi-source heterogeneous information, in which the specification of CORBA is used for reference and the knowledge based automatic mapping mechanism and the object oriented packaging technique are adopted, is put forward to solve the problem of integrating different application object systems. Combined with the practice in Henan power grid, the integration principle and its implementation approach to share the data information resources, including the integration of graphics and the structural parameters of power grid and so on, are analyzed in detail, and the integration of Dispatcher Training Simulator (DTS) with SCADA/EMS is achieved, so the high-grade integration of DTS with heterogeneous systems is realized. The presented integration framework is an open and versatile one with high-grade automation, so a new method to the modeling for integrated simulation of heterogeneous systems is provided.
