摘要
目前,我国煤矿井下生产系统的供电距离更长、工作面电气设备容量加大,设备种类数量繁多、供电结构更复杂,往往井下供电会出现无功功率低、末端电压波动、谐波分量严重等问题,影响井下供电系统的电能质量。新一代的静止无功补偿技术SVG在井下的应用,不仅解决了传统的问题,如提高功率系数降低损耗,还能实现消除谐波、稳定末端电压等新功能,为越来越复杂的煤矿井下供电环境改善以及电能质量的提升提供解决方案。
At present,the power supply distance of our country coal mine production system is longer,the capacity of electrical equipment in the working area is increasing,the type of equipment is various and power supply structure is more complex. The new generation of static var compensation technology in the application of SVG, not only solve the traditional problems, such as improving power factor to reduce loss, but also to achieve the elimination of harmonic, stable end voltage and other new features, for more and more complex coal mine underground power supply environment imFrovement and power quality to provide solutions.
