| 摘 要： | 利用正弦函数和余弦函数的正交性求出基波参数，进而可测量出谐波电流和无功电流；利用正弦和余弦的对称性可减少计算量；用递推运算可进一步减少计算量。文中对方法进行了仿真，仿真表明该方法具有很高的精度。

| Abstract: | Harmonics current and reactive current measurement are needed for APF. Fundmental parameters can be calculated by the orthonormal character of sine function and cosine function, harmonics current and reactive current can also be measured. Calculation can be decreased by the symmetry of the sine function and cosine function, as well as the step operation. Simulation shows that the method has high precision. |
