Summary
This report contains a load set calculation and design variation calculations for the DOWEC 6 MW
wind turbine. The wind turbine is modelled in Phatas IV by ECN. The calculations of the “baseline”
wind turbine are performed with executable “phat6MW.exe” dated 020502. For the design variations
other executables were used. The load set is programmed by Stentec B.V. according ref. [2]
description.
The resulting fatigue and ultimate loads are presented in time response diagrams, extreme values
tables, statistics and VBC tables (1Hz equivalent signals), generated by Stentec B.V.’s post
processing program ADAP. All results are stored on CD C45.04/01.03/03. The results of the design
variation calculations are stored on CD C45.04/01.03/03 and are used to generate “cost of energy”
tables.
The decisive values can be used for optimalisation and design detailling.

1 Introduction
In order to calculate the strength of a wind turbine a set of loads and load combinations is prescribed
by the certification authority. This report describes the load set and results according to IEC2 class C
and DNV regulations for the DOWEC 6 MW wind turbine. It is the purpose that the fatigue and
ultimate strength of the wind turbine comply with this standard. The wind speeds and turbulence
intensities that are used for the load set are given by NEG Micon and ECN ref. [2].

2 Wind turbine
The DOWEC MW6 wind turbine is a three-bladed off shore wind turbine with a rotor diameter of 129
m. and a rated power of 6 MW. The turbine start up wind speed is 4 m/s and has a nominal wind
speed of 12.1 m/s. Rated rotor speed is 11.84 rpm. The blades on this variable speed wind turbine
are controlled by an active pitch control system. Normal pitching speed is 5º /sec. while emergency
speed is 10º /sec.
The hub height of the DOWEC is 91.4 m. above sea level. Total height of the tower is 110.2 m. from
the sea bottom.
A description of the DOWEC wind turbine can be found in ref. [3] and ref. [14].
2.1
Wind turbine modelling
The DOWEC 6 MW wind turbine has been modelled with the dynamic response program Phatas IV
by ECN. An overview of the used program and input files can be found in Appendix A.
For the simulation the DOWEC wind turbine with 21 meter foundation was used without
hydrodynamic loading.

3 Load set.
3.1
Introduction.
A loadset has been defined by NEG Micon and ECN, ref. [2]. The load cases are based on IEC2
class C regulations and DNV regulations for off shore wind turbines. According this load set
description Stentec B.V. made two series of input files for Phatas IV, one for the fatigue calculations
and the other for ultimate loads calculations. Stochastic wind models were generated with Swifti2.
3.2
Definitions of the quantities.
The definition of the quantities is according to the blade, hub and tower co-ordinate system of the
Terms of Reference ref. [4]. A short description of the used quantities in Phatas is given below.

4 Results
After the PhatasIV calculations the digital output files were converted in ASCI format with the Phatas
postprocessor PHPOST.exe. PHPOST can convert 128 variables maximum per postprocessing run.
Stentec B.V.’s post processor ADAP was used to generate extreme values tables, statistics and for
fatigue analysis 1Hz equivalent signals. The extreme values were extracted from all load cases of
the ulitmate and fatigue load set. For the fatigue analysis only load cases 12 a/b, 18a/b and 24a/b
were examined. These are considered to be the decisive load cases for optimalisation.
4.1
Maximum tower foot bending moment
According IEC 6.1 36 simulations are performed with the wind turbine idling at a windspeed
(stochastic model) of 41.5 m/s. Each load case is calculated with a different wind direction. To
improve the idling of the model, the pitch angle of the blades is set at 85º.
The maximum resulting tower foot bending moments are:

The load case E50335 generates the highest tower foot bending moment. This load case is repeated
8 times, but for each load case a different stochastic model is used. The maximum tower bending
moments are:

From these values it can be determined that the mean maximum tower foot bending moment
Mxt[01] is: 149333 kNm.
It has to be noted that this value is not the absolute highest value. When looking at the extreme
values tables load case GrEog1Voc generates the highest tower foot bending moment Myt[01],
which is -281560 kNm (with = 1.00) . For a plot of this loadcase see Appendix C.

1 Hz equivalent signals
Of the fatigue load set the following load cases are selected for the optimalisation process: 012,
018, and 024. The most important design parameters are analysed by rain flow counting the signal
for damage assessment and the determination of a 1 Hz equivalent signal. This procedure will be
repeated for design variations. By comparing values conclusions can be made about the
improvement of the design.
The results of the calculations of the base line are presented in the following table:

5 Design variations.
By altering Phatas IV input files and/or executables by ECN and Stentec, design variations are
created. These are compared with the baseline DOWEC turbine. Not the whole load set is used, but
just the load cases that have caused the highest loads. The following load cases are chosen to
calculate the design variations: 012, 018, 024, 1B-5Vo, E50025, E50335, EcdVrb, Eog50-12,
GrEog1Voc.
5.1
Cost of energy.
To clarify the results, the cost of energy per design is calculated according ref. [9], chapter 5.
The cost of a wind turbine can be broken down in cost per component. Important design (and cost)
drivers of a component are the extreme and fatigue loads it has to withstand. A further break down is
achieved by weighing the several loads. By comparing load changes with the baseline configuration
an estimation can be made about the change in cost of the wind turbine.

If the change in annual yield is known as well, the cost of energy can be calculated by dividing the
wind turbine cost by the yield:
Influence of design variation on cost of energy =
(change in wind turbine cost)
(change in annual yield)
It must be noted that these variations are one dimensional and therefore very crude. For example a
tip speed variation would be more effective with a blade design adapted to that speed. But in this
case the only change is the tip speed.
The results should not be judged for their values, but used as a guideline to further develop the 6MW
DOWEC.
5.2
Structural pitch.
By changing the position and rotation of the girders in the blades, the stiffness properties are
changed. The changed behaviour of the blades should result in smaller tip deflection and a decrease
of fatigue and extreme loads. 4 redesigns (ref [10]) are calculated :
• tr+5-5, girders 0.5o rotated, at tip girder suction side 0.5m to aft and girder pressure side
0.5 m forward.
• tt+5, girders 0.5o rotated, at tip girder suction side and girder pressure side 0.5 m aft.

•
tt+5-5, girders 0.5o rotated, at root girder suction side 0.5m forward and girder pressure
side 0.5 m aft.
• tt-5+5, girders 0.5o rotated, at root girder suction side 0.5m to aft and girder pressure side
0.5 m forward.
The modified turbine models are tested with load cases 008, 012, 018 and 024, 231 and 234. Load
case 231 is a stochastic windspeed of 12 m/s with –20o yaw, 234 a stochastic windspeed of 25 m/s
with –20o yaw.
To prevent interference of the blades with the turbine, the dynamic behaviour of the tower has been
switched off. Also the baseline loadcases have been recalculated with tower dynamics off.
This explains the difference in baseline loads in the table below, compared to the other
variations.The results of the simulations are stored on CD C45.04/01.03/03 . The extreme and
fatigue tables can be found in Appendix D as well.
5.2.1 Cost of energy.
The calculation of the cost of energy can only be based on the fatigue and extreme loads of the
blades. Gearbox loads, tower loads and energy production are not taken into account because the
aerodynamics of the blades are not changed and the tower dynamics are off. Therefore it is
assumed that these parameters have not changed.
Based on the changed loads the results in relative turbine costs are as follows:

Tower eigenfrequencies.
The influence of the tower eigenfrequencies on the turbine behaviour is investigated by creating 8
new tower models with the following eigenfrequencies: 0.150, 0.175, 0.200, 0.225, 0.250, 0.300,
0.350 and 0.400 Hz. The clamping stiffness and material properties of the baseline tower were
modified iteratively to alter the eigenfrequency. The frequencies were calculated with Phatas IV.
The results of the load case calculations can be found on CD C45.04/01.03/03. The extreme and
fatigue tables can be found in Appendix E as well.
5.3.1 Cost of energy.
Compared to the baseline gearbox loads and annual energy production have not changed. Only
blade and tower loads were used to determine the change in turbine costs. When comparing the
towers the following table can be made:

The influence of the design variations on the cost of energy is similar to the relative turbine costs.
What this table doesn’t show is a resonance of the tower with the 0.200 e.f. The 1P oscillation
happens at 0.200 * 60 = 12rpm. Since this is very close to the nominal rpm of 11.844rpm,
considerable fatigue damage is the result. The DOWEC wind turbine cuts out at 14rpm, so the
lowest possible tower e.f. should be above 14 / 60 = 0.233Hz.

Plots in Appendix I show the behaviour of several towers.
5.4
Turbine control.
Three alternative controls are modelled (ref. [11]) and calculated, a High Tip Speed (HTS), Low Tip
Speed (LTS) and a Peak Shave (PS) control. The HTS turbine runs with a nominal speed of 12.58
rpm at Vr=11.7 m/s. The LTS turbine runs with 10.36 rpm at Vr=12.3 m/s.
The first eigenfrequency of the tower of the HTS control turbine is increased from 0.242 to 0.257 Hz.
This will prevent undesired excitations due to the higher nominal speed.
The PS control does not change the rpm, but limits the maximum axial force on the hub in this case
by opening the blade pitch 2 degrees at Vr. The design of the PS control is based on ref. [15].
The results of the load case calculations can be found on CD C45.04/01.03/03. The extreme and
fatigue tables can be found in Appendix F as well.
5.4.1 Cost of energy.
For the cost of energy of the HTS and LTS control the average gearbox torque and the annual
production is calculated. The average gearbox torque is determined by calculating the average
torque of the generator power curve from the Phatas input file “DowecHTS.inp” and “DowecLTS.inp”.
Phatas IV is used to create a PV curve of the HTS and LTS control. Consequently with the Phatas
post processing program “Eprod” the annual production is calculated. The results are presented in
the table below.

For the PS control the generator torque table is not changed. Therefore only the blade- and tower
parameters and the annual production is taken into account for the calculation of the cost of energy.

It was expected that the PS control would give greater benefits. Analysis of the load cases and the
results show that the axial force (Fxn) is only reduced with 6.10% at loadcase 12PS, compared to
the baseline loadcase 12. When running a simple test loadcase with a linear changing wind from 4 to
25 m/s, the Fxn at Vr is even higher than that of the base line as can be seen in Appendix J.
It must be concluded that the present peak shave control for the 6MW DOWEC does not work
properly. It must be revised and tested prior to drawing conclusions.

Tapered blade.
ECN has designed a blade with more taper than the baseline blade, ref [12]. The cone angle is
changed to –2.4o. The input file “DowecR6.inp” is revised to reflect the new blade design. The
turbine control is the same as the baseline. The results of the load case calculations can be found on
CD C45.04/01.03/03. The extreme and fatigue tables can be found in Appendix G as well.
5.5.1 Cost of energy.
The blade- and tower parameters and the annual production are taken into account for the

Low Lambda control.
With the Low Lambda control (LL) the rated (wished) rotorspeed changes with the magnitude of the
wind. At high wind the rotorspeed is lower than for example at Vr. This will decrease fatigue damage,
but also makes it possible to keep the wind turbine in operation at windspeeds higher than Vo
(baseline). An other option is to investigate the effects of an increased rated rotorspeed from Vi until
Vr.
For this design variation no new turbine control is programmed, but output from the turbine control
variations (par. 5.4) has been used to create new load sets.
The following load sets have been created:

The standard load cases apply to a rotorspeed of 11.84 rpm, the LTS (Low Tip Speed) load cases
10.36 rpm and the HTS (High Tip Speed) loadcases to 12.58 rpm. For this Low Lambda analysis
load case 027LL was generated to assess the fatigue damage of a LTS turbine at a stochastic
windspeed of 27 m/s (wished rotorspeed at 10.36 rpm).
The occurrence of the load case is based on a Rayleigh distribution with a Vm of 9.2 m/s. The Pmean
is the average generator power of the load case and is used to calculate the yearly production.
The results of the load case calculations can be found on CD C45.04/01.03/03. The 1Hz equivalent
fatigue tables can be found in Appendix H as well.
5.6.1 Cost of energy.
The blade- and tower parameters and the annual production are taken into account for the
calculation of the cost of energy. The annual production is calculated by ADAP using the occurance
and mean power from table 18. The average gearbox torque could not be used, since the
rotorspeed-shaft torque table differs per loadcase. Also extreme values are not available because
the loadsets consisted only of fatigue loadcases. The results are presented in the table below.

Based on the simplified Low Lambda load sets and the cost of energy model, it can be concluded
that only LL1 has a reasonable decrease in fatigue damage. But because the annual production is
lower, the cost of energy increases. LL3 to LL5 even cause more fatigue damage than the baseline
while production is lower than the baseline.

6 Conclusion.
Based on the turbine description of ECN ref. [3] a PhatasIV load set has been generated. With the
results of this final load set the components of the turbine can be checked by NEG Micon or ECN for
ultimate and fatigue loads according to the IEC and DNV regulations.
From the results of the load cases it is shown that the turbine behaviour is conform the load set
description given by NEG Micon ref. [2]. But the extreme loads are not in accordance with the
expectations. When table 10 is compared with ref. [13] it can be concluded that the maximum tower
top tilt moment Myt[02] is 1.7 times higher than calculated statically. The highest tower bottom tilt
moment Myt[01] is 2.5 times higher than expected.
A possible cause for this large difference might be the ECN modelling that allows short generator
overshoots while originally the 6MW was considered to be an absolute highest value.
Key load cases are used to calculate DOWEC design variations. Of the most important parameters
tables with extreme values and 1Hz equivalent signals can be found on CD C45.04/01.03/03. To make
the large amount of data understandable, it has been used to calculate relative turbine costs and
changes in cost of energy.
It is shown that tower frequency and turbine control have the largest influence on the cost of energy.
An increase or decrease in tower frequency of more than 0.1Hz, a lower tipspeed or the use of peak
shaving will have a beneficial influence on the cost of energy of the 6MW DOWEC.
