Mathematical modelling park of constant speed wind-power plants

The right choice of windmill type, connection place, power size and rate statistic and dynamic parameters of power system is the scientific, technical and technological problem. Existing systems with windmills measurement summation are using to tackle the problem. Mathematic models are using to calculation. The single lumped mass windmill drive train model is mostly used. But the simplified two-mass model with the 3-th -5-th number Thevenin mathematic model gives better results. The drive train model consists of the inertia of both the turbine and the generator. The connecting shaft is modeled as a spring and a damper.
