摘要
研制了1套静止无功发生器(SVG)装置,使用基于瞬时无功功率理论的方法进行无功电流检测。首先分析了SVG的控制策略,采用直接电流控制三闭环控制结构,在此基础上利用SVPWM调制技术产生所需要的脉冲驱动信号。然后提出了SVG的软硬件设计方案,并介绍了SVG保护系统的设计方法。
A set of static var generator （SVG） device was developed, which uses a method based on instantaneous reactive power theory to detect reactive current. The article analyzed SVG control strategy; adopted direct current to control three closed - loop control structure, based on which used SVPWM modulation to produce the desired pulse drive signals. Then the article introduced software and hardware design scheme of SVG and the design of the protection system.
