摘　　要：研制了±50kV.A的配电网静止同步补偿器(Distribution Static Synchronous Compensator,简称DSTATCOM)。其硬件主电路以IGBT功率模块为开关器件,采用PWM整流器结构。通过检测电路采集电流电压信号,利用TMS320F2812型DSP处理器进行算法处理和PWM脉冲输出。为提高系统的动态性能,采用直接电流控制策略,通过矢量变换消除静态误差,提高PWM开关频率等措施来减少输出谐波。实验结果验证了该方案的正确性。The paper introduces the realization of ±50 kV.A distribution static synchronous compensator（DSTATCOM）.The PWM rectifier topology structure with IGBT module is used in hardware circuit design.The measurement circuit sam-ples current or voltage signal.The algorithm and PWM output are implemented with the high performance DSP TMS320F2812.The direct current control strategy is used to improve the DSTATCOM dynamic performance and the static error is eliminated by vector transform,the methods to improve the PWM frequency can reduce harmonic,and the correct-ness of design is verified by the experimental results.
