配置SVC装置改善煤矿母线电压波动

文章通过分析非线性冲击负荷以及感应电动机对煤矿母线电压的影响,指出非线性冲击负荷和感应电动机是影响煤矿母线电压波动、闪变乃至稳定的重要因素。采取了在保持原有固定无功补偿不变的基础上,仅在电动机较集中的煤矿母线或接有一定数量的冲击性负荷母线上安装SVC装置,使其仅承担波动的那部分负荷。结果证明该方法能有效地改善煤矿电压波动、闪变的现象。

SVC Device Installed to Improve Voltage fluctuating of Mine Bus

With the analysis on the non-linear impact load and the induction motor affected to the mine bus voltage,the paper pointed out that the non-linear impact load and the induction motor would be important factors affected to the voltage fluctuation,flicker and stability of the mine bus.The solution would be that base on the original fixed idle compensation to keep no variation,a SVC device should be installed on the mine bus with a large number of electric motors or with certain number impact loads to take the...
