Simulation of transient processes at operation of stand-alone wind turbine with backup power source
Keywords:
wind power engineering, wind power facility, mathematic modeling, transient processes, power regulationAbstract
The paper presents the mathematical simulation of operation of the stand-alone system composed of a wind turbine, induction generator, synchronous condenser, diesel engine as a backup power source and a variable control load. The non-standard model is used to set the wind speed; it considers random fluctuations, gusts and calm periods. Results of the simulation at nominal output of 275 kW and 380 V line voltage prove that frequency variations during regulation do not exceed 1 Hz, whilst voltage fluctuations are less than 15 V.
