| 摘 要： | PI是应用广泛的实时／历史数据库系统，在高效数据访问、海量数据存储等方面表现出关系数据无法比拟的优势．PI提供了比较完善的PI数据库访问工具，但没有提供数据分析和挖掘工具，实现数据分析和挖掘，需要利用第三方开发工具．研究了PI数据库访问的原理以及C～Builder利用Pl-API访问PI数据库的方法，并将该方法应用到电力负荷预测系统中，实现了PI中电力负荷数据的访问．实际应用说明该方法是正确有效的．

| Abstract: | PI,a real-time/historical database,had been extensively applied in plants information process which was superior in efficient access and large data storage to relational database.PI had provided many perfect tools to access PI,but had not provided tools for data analysis and mining.In order to implement data analysis and mining on PI,three-party tools should be involved.Currently,there were few works about how to access PI using the three-party tools.It was investigated the access principles of PI system,and the approaches to accessing PI database by C builder,and then applied the approach in power load prediction system to access power load data from PI.The practical application showed that the approach was correct and valid. |
