摘要

针对电力线路在进行无功补偿时

投切电容器组产生的涌流和过电压的危害

提出了一种基于PIC单片机的同步关合技术。它采用PIC单片机作为主控芯片

进行数据处理和发出控制指令。功率因数的测量采用了CS5460A芯片。同步关合技术实现的关键是准确地预测合闸时间。笔者提出利用双线性插值法进行合闸时间的预测

且对数据进行了归一化处理

以降低单片机的数据处理量。最后给出了试验结果分析。分析结果表明

利用双线性插值进行合闸时间的预测是可行的。

Abstract

In order to decrease surge current and over voltage when the var compensation capacitors being plunged into power system

the synchronous closing technology based on PIC was described in this paper.The PIC as the CPU was used to deal with data and sends controlling order

and CS5460A was used to measure power factor in the synchronous closing technology system.Forecasting the closing time accurately was the key point of the synchronous closing technology system.Double-bilinear interpolation with forecasting the closing time was described in this paper.In order to simplify the CPU work

normalization was applied to the data.The result of experiment shows that double-bilinear interpolation with forecasting the closing time is practicable.
