低压无功补偿装置在选煤厂的应用分析

摘要

选煤厂电动机等电力负荷大部分属于感性负荷，供电系统功率因数因此而较低；变频器、电子元件等仪器设备的使用更导致低压供电系统电流谐波问题严重，电能质量下降。为有效提高选煤厂低压供电质量，减少对设备的冲击，采用在低压分段进行无功补偿的方式进行功率补偿，确保供电系统功率因数及供电质量。%Coal motors and other electrical loads are inductive load most of the power supply system power factor therefore lower; inverter, electronic components and other equipment are more low-voltage supply system current harmonics cause serious problems, power quality. in order to improve the quality of coal preparation plant low voltage power supply, reduce the impact of the equipment used in low-voltage reactive power compensation segmented way to compensate for power, ensure the power supply system power factor and power quality.
