| 摘 要： | 首先分析了某矿现代化改造后各设备所引起的电网谐波现象和谐波对矿井安全的危害。其次,在此基础上设计了采用三相并联型有源电力滤波器实现谐波治理和无功补偿的控制方案,并对该滤波器进行了数学建模。最后以该矿副井提升机作为非线性负载对象,对该控制模型进行了仿真。仿真结果表明,该控制方案可行,系统具有良好的动静态性能。

| Abstract: | First the source and the harm of harmonic of a coal in modernized transformation are analysed.Secondly,a parallel three-phase active power filters is designed to control the harmonics and reactive power compensation.Meanwhile,building the mathematical model of the filter.Finally,the control model is verified by simulation according to the mine elevator as a non-linear load and the results of simulation show the control scheme is feasible,and have good dynamic and static performance. |
