在开发配电网无功优化软件时,没有采用以数据库管理系统作为后台数据管理工具的常规做法,而是自主设计和实现了一个数据管理引擎,以此来代替数据库管理系统为优化计算提供数据服务。该引擎作为一个模块嵌在无功优化软件中,主要完成解释执行SQL语句、数据存取、数据组织及查询处理等功能。文中着重阐述了数据管理引擎的静态结构及其关键部分的实现思路。该引擎具有操作数据快速、使用简便、易于扩展等特点。
In the development of distribution network reactive power optimization software, did not use the database management system as a background data management tools, conventional practices, but independent design and implementation of a data management engine, as a substitute for database management system to provide data for the optimization calculation service. The engine as a module embedded in the reactive optimization software, the main completion of the interpretation of the implementation of SQL statements, data access, data organization and query processing and other functions. The article focuses on the static structure of the data management engine and the realization of the key part of the idea. The engine has the characteristics of fast operation data, easy to use and easy to expand.
