| 摘要: |
| 针对静止同步补偿器（STATCOM）电压控制问题，提出了一种基于多模型PI的STATCOM控制方法。该方法将多模型方法和PI控制方法相结合，控制器采用PI控制器结构，具有结构简单、计算时间短、易于实现等优点。同时利用多模型的方法，来适应不同冲击性负载下接入点电压幅值降低的不同给PI控制器造成的影响，从而满足接入点电压控制的精度与速度。仿真研究表明，多模型PI控制器相比一般PI控制器，具有更强的对于接入点电压变化的适应能力和更高的补偿精度，证明了所提方法的有效性。 |

| Abstract: |
| A multi-model PI controller is proposed for the voltage control of STATCOM，which applies multiple models to PI controller. The PI controller has simple structure，short computing time and easy realization，while the multi-model strategy is applied to ensure the accuracy and speed of voltage control at connecting point for different impactive loads. Simulative results show that，compared to traditional PI controller，the multi-model PI controller has better adaptability to the voltage variation at connecting point and higher compensation precision. |
