摘　　要：电气参数是电力系统自动控制和保护的重要依据。基于虚拟仪器和电气参数测试的技术特点,提出基于频谱校正的电气信号测量算法,该算法适用于多种电气参数测量。在 Lab VIEW 软件开发平台上对算法的仿真表明,算法具有计算量小,响应速度快,计算结果精确性和稳定性高的特点。Electric parameter is an important basis for the automatic control and protection of the power systems. This thesis, based on the technical characteristics of virtual instrument and electric parameter testing, puts forward a digital algorithm for the electric signals by DFT spectrum correction. The algorithm is suit for measurement of various electric parameters. Simulation on the LabVIEW software de velopment platform shows that this algorithm features itself in low calculating volume, quick response, high accuracy and stability in the final results.
