摘要
针对矿井提升机调速性能不理想和对电网谐波污染大等问题进行研究,利用仿真技术搭建3种不同变频器的模型并对变频器相电流的波形和频谱进行比较,提出矩阵式交-交变频器将成为矿井提升机的理想调速单元。
It is a purpose to solve the problem that the unsatisiactory about speed pertormance and the harmonics pollution to power grid caused by the hoister using in coal mine. As reference models of three kinds of frequency convertors founded by simulation tools, comparing and analyzing about the waveforms and frequency spectrum of the frequency convertor output current is done. The result show that the matrix AC-AC frequency convertor would be the optimal speed performance cell of the hoister using in coal mine.
