摘　　要：设计了一种基于DSP的配电静止无功发生器(DSTATCOM)控制系统。为改善DSTATCOM装置的无功补偿性能,系统采用了直流侧电容电压的闭环控制。介绍了控制系统的硬件、软件构成和功能,给出了DSTATCOM装置用于改善电压质量时的实验波形。实验结果表明,该装置能快速补偿因负荷无功功率引起的电压下降。A DSTATCOM control system based on DSP was designed. In order to improve reactive power compensation performance of DSTATCOM device, the voltage closed loop control of DC side capacitor was adopted. The hardware/software configuration and function of control system were introduced, and waveforms of experiment that DSTATCOM device was applied to improve voltage quality were given. The experimental result shows that the device can compensate the voltage drop caused by reactive power of load.
