基于Delphi平台平滑曲线的算法实现

为了便于观测与分析电力系统的运行情况,配电测控中心需要将采集的电能数据通过软件输出显示为平滑曲线图.在Delphi软件开发环境下,采用三次样条插值算法程序在原数据点之间插入适当节点,通过其自带图表控件DBChart输出理想的平滑曲线图.结果表明,直接应用算法程序比另行安装第三方图表控件更为简便.

Realization of smooth curve algorithm based on Delphi

To facilitate the observation and analysis of the operation of power system,the power distribution measurement and control center need to output and show smooth curves through software according to energy data collected.In Delphi,using cubic spline interpolation algorithm to insert appropriate nodes between the original data points,and output ideal smooth curve through its own chart control of DBChart.The results indicate that the direct application of algorithm program is simpler than installment of third party control.
