| Abstract: | Normally capacitor convergence compensation device is installed on the low-voltage side of a substation; power factor should not be less than 0.9 after compensation.In design process, however, the influence of medium voltage supply network and traction unit on power factor is often ignored, The article calculates and estimates the degree of influence caused by the ignoring through practical cases. |
