niesymetria napięcia - Opis:
- This paper shows results of simulation investigations of wind turbine with doubly-fed induction generator operation in unbalanced electric power system. The aim of presented research was analysis of impact of network events on the wind power plant mechanical system. In order to realize the investigations a dynamic mathematical model of wind power plant has been created. The model allows for mechanical system of power plant, rotor-side electronic power converter, slip-ring machine and control system. The transmission and the turbine have been modeled as a six mass oscillator reduced to the generator shaft. The study results show that voltage unbalance and short-term voltage dips cause torque surge on the shaft and transmission of the wind power plant. A modification of method of active power control has been proposed in order to reduce the impact load of the mechanical system. The results of simulations of wind power plant transients with modified control system are quite promising: a reduction of impact load of mechanical system up to 72% has been reached.
