摘　　要：主要阐述了应用于配网静止同步补偿器(DSTATCOM)单电流控制方案及其改进策略,并对直流侧稳压问题进行了详细的分析,给出了控制直流侧电容电压稳定的PI参数整定方法,并引入了自适应模糊PI控制器,直流侧电容电压采用PI和自适应模糊PI 2种控制方式进行了对比。对采用所提电流控制策略的DSTATCOM进行了仿真研究,并制作了实验样机。仿真和实验验证了该控制策略应用于DSTATCOM的有效性和可行性,实验结果同时证明采用自适应模糊PI控制的DSTATCOM系统响应速度更快,而且没有超调和振荡,具有较强的鲁棒性。The improved compensation control of DSTATCOM（Distribution STATic synchronous COMpensator） based on independent source current control is presented and the voltage stability of DC side is analyzed in detail. The adaptive fuzzy PI controller is adopted for DC voltage stabilization and the setting of PI parameters is introduced. Comparison is carried out between general PI controller and adaptive fuzzy controller for stabilizing DC voltage. The simulative investigation of DSTATCOM with the proposed control strategy and the test of prototype prove its validity and feasibility,and show that,without overshoot and oscillation,the DSTATCOM system with adaptive fuzzy controller has faster response and strong robustness.
