摘要
随着电网规模迅速扩大,电力系统运行参数数据也日趋复杂,利用数据库来统筹规划各项参数,方便管理和查询是一项非常重要的工作。建立短路电流计算数据库,需要对电网进行系统、全面的认识和了解,分析各项参数之间的联系,快速准确地获取所要数据并进行操作。这是一项复杂和经验性很强的工作,为此,提出了一种基于专家系统的电力系统数据库管理与优化查询的方法。该方法通过专家系统的决策机能,对参数处理给出经验性指导并有效解决问题。
With the rapid expansion of the electrical networks, the data of the electrical system become more and more complex day by day, and using database to classify various data to facilitate management and query is an important job. Creation of the database for short-circuit current calculation demands that the creators should have a systematic and full understanding of the electrical system, and it is a heavy job to analyze the relation among various data and acquire them quickly and accurately to serve operation. To solve this problem, the paper presents a method about electrical system database management and optimized query based on expert system. This method uses the expert system to give an experienced guidance to the data processing, thus effectively solving the problem.
