Abstract

The brake amount of traditional longitudinal differential protection of motor is a fixed value, so that for special extremes the relay is prone to maloperation or refuse to move. According to the motor fault characteristics, I take out a motor longitudinal differential protection principle which is proposed based on the amount of floating threshold brake. It will improve the reliability of the longitudinal differential protection, and the influence affected by transition resistance is reduced. What’s more it can better remove the fault and prevent maloperation.
