论述了乒乓式转子一点接地保护的原理改进方案。通过叠加辅助的直流电源。
This paper presents the principle improvement of time sequence rotor one point earthing protection. With an auxiliary DC power over lapped, this protection is capable to detect the earthing fault of generator rotor winding, which occurs when the generator shuts down or rotates deexcitedly.
