摘要
针对普通晶闸管变流装置深控时功率因数以及谐波问题,本文介绍了6/12脉动双桥串联顺序控制的晶闸管变流装置。通过MATLAB仿真得到了该装置在典型触发角α下,输入电流,输出电流,输出电压波形和相应的功率因数。仿真表明:该变流装置在深控时,功率因数能够得到一定的改善,但浅控时对电网产生不容忽视的谐波危害。
Considering the problem of power factor and harmonic of a deep-controlled thyristor converter, a new approach based on double bridge serial connection sequential control thyristor converter is proposed in this paper. The waveforms of input current, output current, output voltage and correspondingly power factor are obtained using MATLAB simulation, when the converter runs at characteristic phase angle a. The results show that when the converter is deep controlled, power factor can be improved to some extent, but it would take bad effect on electric network during fleet control.
