目前,我国的电力电子技术正处在高速发展之中,高性能大功率器件随之得到了不断地发展与应用,这些器件在提高工业自动化水平以及生产效率的同时,也对电力网造成了谐波危害,分析传统LC滤波器性能的基础之上,文章从煤矿生产中的电网谐波的危害角度出发,研究谐波对于电网环境的危害,并进行了一定的改进,以期对煤矿生产的安全性提供理论性依据。
At present, China’s power electronics technology is in rapid development, high-performance high-power devices followed by continuous development and application of these devices to improve the level of industrial automation and production efficiency, but also on the power grid caused by the harmonics Based on the analysis of the performance of the traditional LC filter, the article studies the harm of the harmonics to the grid environment from the point of view of the hazards of the power grid harmonics in coal mine production, and makes some improvements to the safety of the coal mine production Provide a theoretical basis.
