Abstract：In the electronic-switching passing neutral section system, the dead time of no power supply for locomotive is very short. The phase of contact voltage must be measured should be accuracy and fast. In this paper, several common voltage tracking algorithm are research. Simulation results show that the zero crossing detection and phase-locked loop are not suit for the electronic-switching passing neutral section system voltage phase detector, meanwhile weighted least squares method detect the voltage phase and frequency fast and accuracy,even when there are harmonics in the voltage wave. This algorithm is used in experiment, the voltage phase detection methods, and results verify the analysis is effective in this paper.
