针对工作面供电系统电压波动大、功率因数低、线路损耗大、设备启动困难等问题,提出以SVG技术为核心的无功补偿技术路线,并介绍了一种基于SVG的矿用3.3 kV静止动态无功动态补偿装置的设计方案.工业性测试结果表明,该补偿装置响应速度快,补偿平滑准确,显著提高了工作面设备启动和运行时的功率因数,缩短了启动时间,提高了启动和运行电压的稳定性,有效抑制了谐波,并具有显著的节能效果.%For problems of large voltage fluctuation, low power factor, large line loss, difficult starting of device and so on of power supply system in working face, the paper proposed a technical route of var compensation which takes SVG as a core, and introduced design scheme of mine-used 3. 3 kV static var compensator based on SVG. The industrial test result showed that the compensator has performances of quick response speed and smooth and correct compensation, which improves power factor of power device in starting and running process, shortens starting time, improves stability of starting and running voltages, restrains harmonic wave efficiently, and has obvious energy-saving effect.
