摘要: 分析了静止无功发生器(SVG)的数学模型,基于无源性理论,提出了SVG非线性控制策略。分别在负载平衡与不平衡条件下对该控制策略进行验证,仿真与实验结果表明了该方法的正确性。该方法控制简单,稳态精度高,动态性能良好,鲁棒性强,补偿后谐波含量低,有工程应用价值。

Abstract: The mathematical model of static var generator (SVG) is analyzed. A nonlinear control strategy is proposed based on the passivity theory for SVG in this paper. The control method was validated respectively under the condition of unbalanced load and balance load. Simulation and experimental results show the correctness of the method. The method is simple in control and has better steady precision, dynamic performance, strong robustness, good engineering application value, lower harmonic distortion rate.

Key words: passivity theory; nonlinear control strategy; static var generator; unbalanced load
