摘要
设计了一套基于单绕组变压器隔离型多重化结构的静止无功发生器(Static Var Generator,SVG)系统,讨论了其多重化结构的主电路设计,同时介绍了双闭环控制以及多重化载波移相正弦脉宽调制技术。试验和实际工程应用表明,该装置系统设计合理、可移植性强、补偿速度快、控制精度高、输出谐波含量低,完全满足工程化应用的要求。
Multiple SVG isolated by single-winding transformer is presented in this paper. The main circuit of the system and the double closed-loop control are discussed. The multiple carrier phase shift sine pulse width modulation technology is illustrated. Test and engineering application show that this device is of rational design and with high degree of portability, fast compensation speed, high control accuracy, low harmonic content, fully satisfied the requirements in application.
