随着煤矿机电设备自动化程度的不断提升,输送机、破碎机、工矿电机车等大功率电动机和大型综采设备、变频器等大量非线性负载不断投入,引起较大的无功功率消耗,导致煤矿电网功率因数、供电质量与稳定性下降,给煤矿安全生产及经济效益带来较大影响.静止无功发生器SVG(Static Var Generator)作为新一代高压动态无功补偿装置,响应速度快,配合滤波电容器FC(Filter Capacitor)兼具补偿无功、谐波和不平衡功能,对于提高煤矿电能质量具有良好的作用.对煤矿用SVG无功补偿装置系统参数进行了设计,并介绍了装置应用情况.
With the continuous improvement of the automation level of coal mine mechanical and electrical equipment,high-power mo-tors such as conveyors,crushers,industrial and mining electric locomotives,as well as large nonlinear loads such as large-scale compre-hensive mining equipment and frequency converters,are constantly being invested,causing significant reactive power consumption,lead-ing to a decrease in the power factor,power supply quality,and stability of the coal mine power grid,which has a significant impact on coal mine safety production and economic benefits.As a new generation of high voltage dynamic reactive power compensator,SVG(Static Var Generator)has fast response speed and both functions of compensating reactive power,harmonic and imbalance with FC(Filter Ca-pacitor),which has a good role in improving the power quality of coal mine.This paper designed the system parameters of SVG in coal mine and introduced its application.
