并联型有源电力滤波器在厂矿企业中的应用

Shunt-series active power filters application in industrial and mining enterprises

针对大型厂矿企业传统配电网谐波治理效果不理想,提出采用并联型有源电力滤波器滤除谐波的方法,同时兼顾补偿一定容量的无功功率,并给出并联型有源电力滤波器系统结构与数学模型,完成了基于Matlab的仿真分析和工程应用.仿真结果和现场试验结果验证了该并联型有源电力滤波器在厂矿企业应用的可行性.

Distribution networks of large industrial and mining enterprises are often unable to effectively deal with harmonics problems by traditional electrical filters.A shunt active power filter（SAPF） is proposed to filter harmonics as well as compensate reactive capacity in this paper.The SAPF system structure and mathematical model are presented.Simulations with matlab and applications are carried out.Simulation and on-site experimental results verify the effectiveness of the SAPF application in the distribution networks of large industrial and mining enterprises.
