摘　　要：针对地铁长大区间低压配电设计中大功率风机、水泵配电线路压降大、损耗高的现状,提出了一种应用动态补偿装置(SVG)就地补偿技术。在介绍了SVG装置功能、装置构成基础上,给出了等效电路计算公式。并结合某地铁工程实际算例,采用SVG装置后,可有效降低供电电缆截面,具有良好的经济效益,可在地铁类似工程中推广使用。In view of the current situation of large voltage drop and high loss of high power fan and water pump distribution line in low voltage distribution design of metro long section,a dynamic compensation device(SVG) local compensation technology was proposed. Based on the introduction of SVG device function and device structure,the equivalent circuit calculation formula was given. Combined with a practical example of a subway project,the SVG device can be used to reduce the cross section of the power supply cable. It has good technical and economic benefits and can be used in similar projects in the subway.
