可视化继电保护整定综合软件的数据库管理

目前的继电保护整定软件虽然计算功能比较完善,但多在复杂电网数据建模、数据组织和管理、数据格式的兼容性、定值文件输出的直观性、通用性及与其它相关软件的数据共享和集成等方面存在一定不足,给软件开发者和用户造成诸多不便。本文介绍了在VisualBasic6.0的开发环境下,结合关系型数据库系统Mi crosoftAccess可视化管理继电保护整定计算各种原始参数信息及保护定值的方法,文中论述了该方法的具体实现方案,并指出了其应用于电力系统继电保护领域的前景及实用价值。

Database management of visual integrated software for relay protection setting

Though the current software of the setting of relay protection has perfect calculating functions, it still exists some problems such as data modeling, organization, management of complicated power network, compatibility of data format, directional output of setting files, universality, and data sharing and integration,which have brought so many negative effects to software-users and software-desigers. In view of that, an effective method of visual database management is introduced. Under the development circumstance of Microsoft Visual Basic 6.0, it utilizes the relational database system-Microsoft Access to manage the various original data of setting calculation and setting value in relay protection. The paper provides the concrete implementation scheme in detail, and also describes the future and practical value in application in relay protection field of electric power systems.
