| 摘 要： | 文中提出了一种改进的保守功率理论的电流检测方法,其可以有效地分解出基波有功电流,消除了电压中谐波的影响。将此电流检测方法运用于单周控制的三相三线制有源电力滤波器系统中,搭建的系统仿真及实验结果验证了此方案的正确性,能消除谐波影响并能够对非线性负载产生的谐波电流进行有效的谐波抑制和无功补偿。

| Abstract: | A current detection method of improved conservative power theory that effectively decomposed the fundamental active current and eliminated the influence of harmonic wave on grid voltage was presented in this paper. The current detection method used in the one-cycle control of three-phase three-wire active power filter system, the simulation and experimental results validate the correctness of the scheme,that eliminated the influence of the harmonic wave in the power grid, suppressed harmonic current and reactive power of nonlinear load generated. |
