摘要
工程设计中单调谐滤波器各元件额定容量与额定电压的选取存在一定盲目性。为充分利用滤波装置额定容量增大带来的经济效益、降低成本,建立了目前煤矿典型的6 k V供电系统的谐波电路模型,推导出了模型中各主要元件参数的实用型计算公式,并对谐波电路模型进行阻抗扫描仿真,仿真结果验证设计的滤波装置的准确性,为滤波装置参数选择提供了理论依据。
In the engineering design of single tuned filter, selecting filter elements of rated capacity and rated voltage has some blindness. In order to make full use of filter device rated capacity added value producing economic benefits, reducing the cost, a harmonic circuit model is established in view of the present coal mine typical 6k V power supply system. And a practical calculation formula is derived for the harmonic circuit model, and taking a simulation for the model, to verify the accuracy of the designed filter device. It provides theoretical basis for selecting parameters of filter device.
