摘　　要：研制了一台基于高速运算DSP的高精度动态无功补偿装置。采用动态改变取样电阻,优化DFT算法以及软硬件抗干扰技术,实现数据的精确快速处理,使装置的滤波能力及信噪比有很大提高。实际运行表明,该装置可以快速准确检测并计算电网各项参数,实时控制电容补偿。A dynamic reactive power compensation device was presented, which was based on the high speed operational DSP. Changeable sampling resistance, optimum DFT algorithm and anti-interference technique were used to process the data accurately and quickly and increase filter discrimination and SNR. The operation of the device proves that it can measure the parameters of power system fast and precisely, and achieve real-time reactive power compensation.
