The Protection Setting for 110kV Line Connects to V/V Traction Transformers

Abstract:

In 110kV railway traction the V/V connection transformers are common used. The distance protection performance for 110kV line connects to V/V traction transformer is analyzed in detail. Then some new advices on setting method for such kind of line protection calculation are proposed. This method is applied to several protection devices in Shandong power supply system. The operating result shows the accuracy of this method.
