Abstract:This paper analyses zero sequence protection misoperation of Datang Lubei power plant and offers some anti-interference measures. Meanwhile, in order to avoid misoperation or refusing to move of the relay protection device, it analyses the zero sequence current transformer series-parallel of the secondary connection, when the motors are supplied with more than two cables through more than two above zero sequence current transformer.
