一种基于δ算子的 SVC 自校正控制器

A SELFTUNING SVC CONTROLLER USING δOPERATOR

文章利用自校正控制理论设计了一种基于δ算子的ＳＶＣ滑动极点配置自校正控制器。在普通带变化遗忘因子的辨识算法中，采用给被辨识参数规定活动上下限及当出现大干扰时停止辨识等措施，提高了辨识能力。滑动极点配置方案具有适应能力强的特点。对输电线上装设ＳＶＣ的单机无穷大系统进行了数字仿真。仿真结果表明：在不同工作点，相对于传统的ＰＩ控制，该控制器均能更好地平息系统振荡，具有更好的动态性能及适应能力。

A selftuning SVC controller with poleshifting technology based on δoperator is presented in this paper. Assigning the moving upper and lower boundaries to the identified parameter values and turning on or off the control algorithm to protect estimated parameters from large disturbance enhance the parameter tracking under both transient and dynamic conditions. The use of poleshifting control increases the adaptability. A single machine to infinite system in which the SVC is installed in the transmission line is digitally simulated, the results of simulation show that compared with normal PI controller this controller has better damping characteristics and good robust.
