摘　　要：随着农村经济的快速发展,迅速增长的非线性负荷使谐波问题显现出来,对低压电网中无功补偿设备的安全运行构成很大威胁。根据农村电网中谐波问题的实际情况,提出利用调谐电抗器来抑制谐波的无功补偿。着重分析谐波的原理,讨论无功补偿电路中电抗和电容器参数的计算方法及主要元件的保护措施,并根据负荷的特点采用合理的补偿方式,以实现优化补偿。The harmonic problem appeared with the rapid increase of non-linear electrical load, which is a big threat on the safe running of the reactive power compensation devices in rural power grid. In the paper, the harmonic adjustment reactor was used to suppress the reactive power compensation based on the actual conditions of harmonic problems in the rural power grid. The principle of harmonic wave was analyzed in emphasize, and the calculation method of reactance and capacitor parameter and protection measure of main components were discussed, and then the reasonable compensation mode was used to optimize compensation based on the load characters.
