摘要
分析了煤矿供电系统主接线、运行方式、主要用电设备的特性,以及各支路非线性负荷的变化规律,明确了各支路的主要谐波源。利用电能质量测量仪器对煤矿供电系统中各支路进行测量,获得各电气参数的变化曲线图,并论述各支路谐波的随机变化特性。
By analysis the main connection,operation mode,the characteristics of main electrical equipment and the change law of branch nonlinear load in mine power supply system,the author suggests measuring the branches in mine power supply system with power quality measuring instrument to determine the main harmonics sources and stochastic characteristics and obtain change curve chart of electric parameters.
