微机控制TCR动态无功补偿的研究

The Research of Dynamic Reactive Compensation of TCR Controlled by Microcomputer

本文分析了TCR(Thyrister CpntroL Reactpo)动态无功补偿之原理,提出了采用微机控制TCR动态无功补偿装置的设想及不检测相角而完成无功补偿的新思想;对电容支路的电流采用了选频网铬滤波的合理解决办法;采用双向晶闸管使控制电路得以简化;设计了采用TR801单板机控制的单相TCR动态无功补偿装置之硬件电路及软件程序;通过调试运行;能在1.5ms之内完成各项计算任务。

The paper analyses the principle of dynamic reactve compensation of TCR. (Thyrister Control Reactor), and pnts forward new ideas about dynamic reactive compensation based on microcomputer and the phase angle being not tested in reactive compensaion. A new method of the application of selective frequency network in capacitance circuit are adopted. The hardware and software of TCR controlled by TP801 single board computer (SBC.) have been given out. All calculations can be completed in 1.5 ms. The power factor of the system is stabilized over 0.9.
