【摘要】：通过理论分析环形配电网的谐波放大原理,对比安装在线路中点且阻抗匹配的阻性有源电力滤波器(RAPF)和对称安装在不同位置的分频调节RAPF的抑制效果,提出了一种适用于环形配电网的分频调节RAPF的位置策略。若线路长度小于谐波波长的1/2,靠近线路中点的对称位置为最优安装位置;若线路长度大于谐波波长的1/2,距谐波源1/4波长的对称位置为最优安装位置。与安装在线路中点且阻抗匹配的RAPF相比,安装在最优位置的分频调节RAPF,当其电导增益≥匹配的电导时,均能有效地衰减谐波,获得更好的抑制效果;且电导增益越大,谐波抑制效果越好。同时,该方案对线路参数的改变具有更好的适应性。仿真和实验结果验证了该方案的有效性。
[Abstract]:The harmonic amplification principle of ring distribution network is analyzed theoretically, and the suppression effects of impedance-matched resistive active power filter (RAPF) installed at the middle point of the line and frequency division RAPF installed symmetrically in different locations are compared. In this paper, a position strategy of frequency division RAPF for ring distribution network is proposed. If the length of the line is less than 1 ~ 2 of the harmonic wavelength, the symmetrical position near the middle point of the line is the optimal installation position, and if the line length is greater than 1 ~ 2 of the harmonic wavelength, the symmetrical position of the distance harmonic source of 1 ~ 4 wavelength is the optimal installation position. Compared with the impedance-matched RAPF installed at the middle point of the line, the frequency-division RAPF, installed in the optimal position can effectively attenuate the harmonics and obtain better suppression effect when the conductance gain is 鈮，
