摘　　要：提出一种基于变论域模糊控制的先进静止无功发生器设计方法。在该方法中,采用优化的比例指数型伸缩因子,对电流环的模糊变量论域进行变换,实现了电流环的自适应控制。利用S函数编程设计了先进静止无功发生器变论域自适应模糊电流控制器,并进行了仿真实验。结果表明,与传统的PID控制相比,基于变论域控制的先进静止无功发生器具有较强的抗扰性能和鲁棒性,改善了电力系统的可靠性并提高其输电能力。The design of ASVG based on variable universe fuzzy control is proposed. In this method, the varia- ble universe of the current loop fuzzy is converted by adopting optimized proportional exponential contraction- expansion factor. The adaptive control of current loop is achieved. The adaptive fuzzy current controller with variable universe of ASVG is designed by using S-Function programming. The simulation experiment of ASVG is done. The simulation results show that, compared with traditional PID control, ASVG based on variable uni- verse fuzzy control has the strong anti-interference performance and robustness. The reliability of the power sys- tem is improved, and its transmission capacity is increased.
