静止无功发生器在青岛南京路变电站中的应用

摘要

文中介绍了静止无功发生器(SVG)装置在青岛南京路变电站的应用情况，分析了 SVG 的基本工作原理、补偿控制策略，并现场进行了无功补偿和谐波滤除效果测试。测试结果表明，该 SVG 可以有效改善南京路站接入点电网的电能质量、抑制电压波动并提高功率因数，具有较高的工程推广应用价值。%The application situation of SVG device in Nanjing Road substation in Qindao is introduced in this article. Basic operating principle and compensation control strategy of SVG are analyzed.Field tests in aspects of reactive power compensation and harmonic filtering are conducted,which shows that the SVG can effectively improve power quality,sup-press voltage fluctuation and improve power factor of grid access point of Nanjing Road substation,and therefore should have extended application in similar occasions.
