电压波动的危害及应对措施探讨

On hazards of voltage fluctuation and its countermeasures

阐述了电网和电气设备在电压偏高或偏低条件下运行的危害性,对电压波动的原因及范围进行了分析,并结合铁路用电现场实际情况,提出了加强供电管理、合理补偿无功等调节电压的应对措施,以保证铁路运输的安全畅通。

The paper illustrates the dangers in operating grids and electronic equipment at higher or lower voltages,analyzes the reasons for the voltage fluctuation and scopes,and points out the countermeasures of adjusting voltages by promoting the power-supply management and reasona-ble compensation reactive power,so as to ensure the safety in the railway transportation.
