级联SVG控制系统设计与仿真

针对SVG模型的非线性,强耦合的特点,提出了一种采用以微分几何为基础,运用精确线性化的原理设计控制器,使SVG这个强耦合非线性的系统解耦,分别对有功电流和无功电流进行控制。对于SVG直流侧电容电压的控制,采用PI控制器来控制,通过调节PI调节器的参数来维持直流侧电容电压的稳定。最后,在MATLAB上建立了SVG的仿真模型,仿真结果验证了算法的正确性。

Design and Simulation of Cascaded SVG Control Strategy

Aiming at SVG model of nonlinear,strong coupling characteristic,this paper put forward a kind of use based on the dif- ferential geometry,using the principle of exact linearization to design the controller,what makes the SVG deCOUloling,the strong coupling nonlinear system respectively to control the active current and reactive current.For SVG DC side capacitor voltage control,using PI controller to control,by adjusting the parameters of PI controller to maintain the stability of the DC side capacitor voltage.Finally,the SVG simulation model is established on MATLAB,the simulation results verify the correct- ness of the algorithm.
