ABSTRACT: Aiming at the characteristics of the application of relay setting calculation and the thoughts of employing componentized design, the truss project and system structure of relay setting calculation software, which are based on COM technique, are put forward. And in this paper, relay setting calculation component and basic calculation component of power system are also exploited and realized. Under the GUI exploited by VB and the circumstance of SQL database and the independence to programming language and the adaptability to different applying condition of component are validated.
KEY WORD: component software; relay protection; setting calculation; component techniques
Windows DNA是微软致力于分布式网间应用的直观体现,其结构示意图如图4所示。其中涉及到许多技术细节和通用服务。而在各层都有所体现的、最为重要的技术就是COM和COM+。COM是所有DNA(Distribute Internet Application)三层系统使用的核心技术,可简单的理解为快速的、面向对象的、可以打包的技术。4.2.2继电保护整定计算软件的体系结构
