摘要:
主要研究二极管钳位三电平静止同步补偿器中的控制策略问题,对于传统解耦控制策略中DQ轴都需要电感的准确值,而实际系统中电感量值会变化的问题,提出对传统解耦控制进行改进,得出无需电感值的解耦控制策略.然后就60°坐标系在虚拟SVPWM算法下直流母线电容电压的平衡控制方法进行了仿真研究.最后搭建了基于新型解耦控制策略的系统仿真模型进行仿真验证,并动手搭建以DSP2812最小系统为主控制器的实验平台,进行了基于新型控制策略的无功补偿实验,实验结果表明，理论分析和仿真结果的正确性.
Abstract:
This paper studies the control system of diode clamped three-level inverter in STATCOM. The vari-ation of inductance can affect a control method. The paper proposes a control method which can ignore the in-ductance and studies how to stabilize capacitive voltage difference in VSVPWM on 60° Coordinate Frame. Thesimulation verification is combined with simulation model. Finally,the simulation verification of the systemwhich is based on decoupling control is built with the system simulation model. The experimental platform usesDSP2812 as the main control chip of minimum system. The experiment results show the accuracy of the theo-retical analysis and simulation performance.
