摘　　要：本文对SVG的谐波抑制、变压器直流偏磁抑制等关键技术进行了研究,满足两段母线分列、并列运行的要求,成功研发出国内首套20kV配电网,集中-分布综合补偿静止型无功发生器(SVG)。在通过RTDS仿真验证了关键技术正确性的前提下,在工程现场进行调试投运,结果表明此SVG运行稳定、满足了苏州工业园区高电能质量的需求。In view of the problems such as harmonic, transformer dc bias, this paper has carried on the key technology research, satisfied the two bus respectively and the requirement of parallel operation, and then successfully developed the domestic first set of 20 kv distribution network - centralized distribution comprehensive compensation type static var generator (SVG). On the premise of verifying the correctness of the key technology through RTDS simulation, the debugging and commissioning of the key technology is carried out on the project site. The results show that this SVG runs stably and meets the user's requirements.
