摘　　要：深入研究配电网中的无功补偿及谐波治理技术,提出一种结合静止无功补偿器(SVC)和有源电力滤波器(APF)的综合治理方案。该方案通过SVC提供动态无功支持,维持节点电压稳定,同时通过APF有效滤除谐波,提高电能质量。在实际配电网中的应用表明,该方案能够显著提升系统的功率因数,降低线路损耗,改善电网的电压波形,减少谐波对敏感设备的干扰。使用智能控制算法在无功补偿和谐波治理中的应用,通过仿真和实际运行数据验证控制策略的有效性和优越性,为配电网的优化运行和电能质量的提升提供有力支持。This article delves into the reactive power compensation and harmonic control technologies in distribution networks,and proposes a comprehensive governance scheme that combines static reactive power compensator(SVC)and active power filter(APF).This scheme provides dynamic reactive power support through SVC to maintain node voltage stability,while effectively filtering out harmonics through APF to improve power quality.The application in actual distribution networks shows that this scheme can significantly improve the power factor of the system,reduce line losses,improve the voltage waveform of the power grid,and reduce the interference of harmonics on sensitive equipment.This article applies intelligent control algorithms in reactive power compensation and harmonic control,and verifies the effectiveness and superiority of the control strategy through simulation and actual operation data,providing strong support for the optimization operation of the distribution network and the improvement of power quality.
