配电网无功优化软件中数据管理引擎的设计与实现

Design and Implementation of Data Management Engine in Reactive Power Optimization Software of the Distribution System

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。

When developing reactive power optimization software in the distribution system, a data management engine is designed and developed to provide data service instead of Database Management System （DBMS） for optimal calculation. As a module embedded in reactive power optimization software, the engine performs the key functions of parsing and processing SQL, data access, data organization and query management. The engine＇s static structure and idea of implementation of such crucial parts are introduced. It has the advantages of quick operation for data, convenient employ, easy extension and so on.
