The demand distribution profile in per unit values is presented in Fig. Between 20 m and 100 m both methods can produce reasonable predictions of mean wind speed in neutral atmospheric conditions.
Wind speed profile neplan generator#
Permanent magnet synchronous generator (PMSG. The permanent magnet machine dynamic model used for this study is the one embedded in Neplan simulation tool and has the parameters of Table 6. The generator is a permanent magnet synchronous generator designed for low speed.

The cut-in profiles have the same wind speed at roughly 80 m, which is the kite height at the start of the reel-out phase for the minimum elevation. The log wind profile is generally considered to be a more reliable estimator of mean wind speed than the wind profile power law in the lowest 1020 m of the planetary boundary layer. Rotor and generator shafts are mounted to the same shaft without gear-box. 3 Gov TUR Exiter GVVIK P= MW Q= Mvar VVIK02VVIK P= MW Q= Mvar I=0.548 ka Ploss= MW Qloss= Mvar VVIK1 Q= Mvar P= MW Q= Mvar I=0.643 ka Ploss=0.000 MW Qloss= Mvar TR2_VVIK Tap=0 VVIK2 Q= Mvar P= MW Q= Mvar I= ka Ploss=0.000 MW Qloss= Mvar P= MW Q= Mvar I=0.700 ka Qloss= Mvar Wik Fir.= deg Ratio=0.000 Cntrl= P= MW Qloss= Mvar DC P=0.001 MW P= MW Qloss= Mvar DCLine1 P= MW Ploss=1.013 MW Shunt DCLine2 P= MW Ploss=1.012 MW P= MW Qloss= Mvar Ynged Fir.= deg Ratio=0.000 Cntrl= CFC_VVIK CCA_VVIK COL_VVIK MC_VVIK CFC_YGNE CCA_YGNE DC P=0.001 MW P= MW Q= Mvar I=0.699 ka Qloss= Mvar P= MW Qloss= Mvar COL_YGNE P= MW Q= Mvar I=0.699 ka Ploss= MW Qloss= Mvar TR2_YGNE Tap=1 P= MW Q= Mvar I=1.141 ka Ploss=0.000 MW Qloss= Mvar YGNE1 Q= Mvar G14 P=0.895 MW Q= Mvar P= MW Q= Mvar I= ka Ploss=0.024 MW Qloss=0.486 Mvar P=0.919 MW Q= Mvar I=0.142 ka Ploss=0.024 MW Qloss=0.486 Mvar YGNE2 Q= Mvar Gov T1 Tap=0 TUR LoadY P= MW G12 Q= Mvar Q= Mvar I=0.684 ka Ploss=0.015 MW Qloss=0.308 Mvar P=0.015 MW Q= Mvar I=0.113 ka Ploss=0.015 MW Qloss=0.308 Mvar T2 Tap=0 3(9) HVDC-Example designed by STRI () and BCP (Switzerland) Turbine and Governor Turbine and Exiter Rectifier Inverter NG kv u=93.14 % Uang=0.00 NG kv u=91.70 % Uang=0.09 VVIK0 135 kv u= % Uang=0.00 VVIK 135 kv u= % Uang= VVG2AC kv u= % Uang= GDC1 u= % GDC2 u=99.37 % GDC3 u=98.62 % YGG2AC kv u=93.74 % Uang=7.02 GDC_E1 u=-0.00 % GDC_E2 u=0.00 % YGNE 75 kv u=99.96 % Uang=0. These data contain wind speed values at six-hour (6-h). Scaling each wind profile shape such that the wind speed at 100 m equals the previously determined cut-in and cut-out wind speeds yields the respective absolute wind profiles, shown in Fig.
