| 摘 要： | 掌握矿井直流提升系统交流侧电力谐波情况,对了解供电的可靠性十分重要。文章首先在Matlab/Simulink下对直流提升系统进行建模和仿真,旨在从理论上了解直流侧的负载变化对交流侧谐波的影响;其次对一个实际的矿井直流提升系统进行谐波实测和分析,实测结果表明,在大胶带满载运行时,11次谐波电流超标,但谐波电压不超标;最后给出了影响交流网侧谐波的因素和应采取的措施。

| Abstract: | It is very important for mine power supply system to know the level of power harmonic in AC side of mine DC hoisting system.In this paper,firstly,modelling of DC hoisting system was built and simulated under Matlab/Simulation in order to know the influence of load change in the DC side on harmonics in AC side theoretically.Secondly,the harmonics of a practical mine DC hoisting system was measured and analyzed.The measurement result showed that the harmonic current of the eleventh exceeds allowed value but harmonice voltage does not exceeds the allowed value when large bell run in full load.Finally,the factors of AC power side harmonics and suitable measurement were given. |
