摘要
轨道交通运输过程中需要大量的变频设备,导致其电网中含有大量的谐波,这些谐波影响到电网供电稳定性,从而威胁到城市轨道交通运输的安全性和稳定性。有源滤波装置在城市轨道交通中的应用,可以消除电网中的谐波,确保电网运行安全性。
In the process of rail transit transportation,a large number of frequency conversion equipment are needed,which results in a large number of harmonics in its power grid.These harmonics affect the power supply stability of the power grid,thus threatening the safety and stability of urban rail transit transportation.The application of active filter device in urban rail transit can eliminate harmonics in power grid and ensure the safety of power grid operation.
