摘要
以矿井直流提升机供电系统为研究背景,对大功率直流电力传动装置,特别是串联12脉动整流电路进行了谐波特性分析。基于MATLAB软件,仿真研究了谐波源输入电流、输出电压及输出电流的谐波特性,为矿井滤波装置的设计提供了理论基础。针对矿井配电系统的特点,设计了适合矿井电网的LC滤波装置,通过仿真实验说明滤波器对电网频率波动具有较好的适应性。
With the hoist electric net in coal mine as the background, the harmonics characteristics of big DC electric power drives, especially 12- pulse serial converter is analyzed. Based on the MATLAB software, the harmonic characteristics of input current, output voltage and output current are simulated. Accordingly these results provide a theoretic basis for filter design. Presents a new approach for limiting harmonic and improves the reactive compensation using LC filter in power system. The simulation experiments validate the good adaptability of filter to the fluctuating of net.
