1、天津大学工程硕士学位论文中文摘要在工作实践中,汽车工厂供配电用电负荷,特别是冲压和焊接生产线上,由于大量的单相、冲击性、低功率因数及整流电源等用电装置的使用,从而导致电能质量下降,不能满足生产需要,主要体现在功率因数低,谐波含量高,电压降大。本文在从无功功率补偿和谐波抑制基础理论分析入手,对汽车工厂供配电用电负荷质量,特别针对低压配电网中电压不稳问题,解决一汽集团二厂区电压的频繁波动,论述TSC—A双向动态无功补偿装置的工作原理及其控制部分的核心内容,采用晶闸管控制电容器组和自动投切电抗器的方案,运用现代电子技术的理论成果,实现无功功率的双向
2、动态补偿,稳定配电网电压,在晶闸管触发电路的设计上,运用光电零电压触发技术,从而对电力系统提供感性、容性两种无功功率,实现了电压的双向调整,能够最大限度地提高负载的运行功率因数,本文主要分三个部分阐述了无功补偿的基本理论,TSC.A的总体设计结构和原理,TSC.A的关键技术。l关键词】:无功功率补偿;动态无功补偿(TSc);自动投切;零电压触发。天津大学工程硕士学位论文ABSTRACTIntheworkpracticeofautomobilefactories.especiallyatthestampingandweldinglines,th
