电压跌落问题由来已久,但研究并不深入,尤其是煤矿电网的电压跌落问题得不到应有的重视。文章分析了煤矿电网电压跌落的原因以及带来的危害,给出了相应的防治措施,并着重介绍了以DVR装置为代表的动态补偿技术。希望引起相关单位的注意,做到防患于未然。 Voltage drop has a long history, but the research is not deep, especially the problem of voltage drop in the coal mine power grid should not be given due attention. The paper analyzes the causes of voltage sags in coal mine power grids and the harms brought about by them. The corresponding prevention measures are given, and the dynamic compensation technology represented by DVR devices is emphatically introduced. Hope to attract the attention of relevant units, so take preventive measures.
