摘　　要：研制了一套基于数字信号处理器DSP的发电机电压扰动量采集系统,采用TMS320F2812型号的DSP芯片,设计了电压扰动采集和分析系统硬件电路。根据瞬时无功功率理论,提出一种计算瞬时电压有效值的方法,并采用C语言编制了相应的系统软件,能够实时采集发电机定子三相电压、电流和转子电压、电流,并且能够实时进行三相电压扰动量的提取。最后通过三相标准电能表校验装置(XL803)进行了采集精度校验,达到了预期目标。This paper developed an acquisition system of generator voltage disturbance based on DSP. Firstly, the type of TMS320F2812 DSP chip was adopted, and the hardware circuit of voltage disturbance acquisition and analysis system were designed. Then according to the theory of instantaneous reactive power, a method of calculating the effective value of transient voltage was proposed, and the corresponding system software was programmed by C language, which can real-time acquire three-phase voltage and current of generator stator, voltage and current of rotor, and can real-time carry out the fluctuation extraction of three-phase voltage. Finally the three-phase voltage and current were acquired by three-phase standard energy meter（XL803） to verify the acquisition accuracy, and achieved the expected target.
