Abstract:
Doubly-fed induction machines (DFIMs) are widely used for wind power plants and variable-speed drive pumped-storage hydro stations. Ensuring the proper response from machine protection systems is paramount to prevent unplanned shutdowns and to reduce damage during internal faults. This paper introduces a novel DFIM model specifically designed for real-time digital simulation. The model exhibits high flexibility, accommodating a diverse array of electrical and mechanical parameters. Moreover, it can simulate a wide range of internal faults on both the stator and rotor. This paper shows how the model can be used for protection testing of stator and rotor phase faults, ground faults, and turn-to-turn faults.
