摘要
本文提出了一种连续调节消弧线圈电感的新方法。通过改变与部分消弧线圈电感相并联的晶闸管的导通时间,就能够连续改变消弧线圈的等值电感。同时,采用增大电网脱谐度的方法来限制电网正常运行时中性点偏移电压不超过15%额定相电压。
A new control method for continuously adjusting the inductance of are suppression coil is presented in this paper. The equivalent inductance of are suppression coil can be adjusted continuously by varying the power on time of thyristor which is connected in parallel with a part of are suppression coil. In addition, during the normal operation of power system the neutral-to-ground voltage can be restricted within 15% of the rated phase-to-neutral voltage by this method.
