- Abstract:
-
The implementation method of induction motor model in EMTP (Electromagnetic Transient Program) and the simulation method of rotor broken strip fault are introduced. The faults of broken bars with different numbers of rotors are simulated, and the changes of rotor current and stator current side frequency components are analyzed. The following conclusions are drawn: after the rotor guide strip is broken, the rotor guide strip current increases; The more broken strips, the more obvious the increase in rotor guide strip current; The closer the guide strip is to the fault location, the greater the current increase, and the farther away the increase is smaller. The edge frequency component in the stator current increases with the increase of the number of broken bars, but the number of broken bars increases to a certain number, but decreases.
