Its purpose is to provide the appropriat e level of protection against damage from hazards from these systems during their planned lifetime. This part of IEC 61400 is concerned w ith all subsystems of SWT such as protection mechanisms, internal electrical systems, mechanical systems, support structures, foundations and the electrical interconnection w ith the load. While this part of IEC 61400 is similar to IEC 61400-1, it does simplify and make significant changes in order to be applicable to small turbines. This part of IEC 61400 applies to w ind turbines w ith a rotor sw ept area smaller t han 200 m 2 generating at a voltage below 1 000 V a.c. or 1 5 00 V d.c. . This part of IEC 61400 should be used together w ith the appropriate IEC and ISO standards. 2.- REFERENCES Basis reference “ IEC 61400-2 Design requirements for small w ind turbines” 3.- WIND TURBINE DESCRIPTION The EPRO70 w ind turbine is a w ind turbine of 3,5 kW in nominal pow er, w ith a permanent magnet generator and a passive variable pitch syst em to control the pow er output and it can w ork as in isolated installations as in grid connected.

This is useful to get t he real forces that appear in the w ind turbine. For certain turbine configurations, the loads can be derived using simple, conservative equations for a limited set of load cases. If the turbine configuration does not meet those configuration requirements, the simple equations cannot be used, instead the alternative aero elastic modelling or load measurements shall be used. In Table 3 there are w ritten all the necessary data to initialize the equations. All the parameters are about the geometry of the w ind turbine and the operational behavior. The Drag, Lift and Thrust coefficients are obtained according to t he IEC 61400 -2. Along the overall process the equations used have been gotten from the IEC 61400 -2 and each one is named before its use.

The IEC 61400-2 consider eight different load cases. Load case A: Normal operation. The design load for “ normal operation” is a fatigue load. The load case assumes constant range fatigue loading for the blade and shaft, these ranges are given below . The ranges are to be considered in the fatigue assessment as peak-to-peak values. The mean values of the load ranges can be ignored. The fatigue loading on the blade w ould be considered to occur at the airfoil – root junction or at the root – hub junction, w hichever is determined to have the low est ultimate strength. The calculated stresses are the combinat ion of the centrifugal loading (FZB) and the bending moments (M XB and M YB). The fatigue load on t he rotor shaft shall be considered at the rot or shaft at the first bearing (nearest to t he rotor). The range of the stress shall be calculated from t he combination of the thrust loading (Fx-shaf t ), t he torsion moment (M x-shaf t ) and the bending moment (M shaft ). Load case B: Yawing For this load case, the ultimate loads (gyroscopic forces and moments) shall be calculated assuming t he maximum yaw speed ωyaw ,max occurring w ith n design. Load case C: Yaw error All turbines operate w ith a cert ain yaw error. In this load case, a yaw error of 30° is assumed. Load case D: Maximum thrust The SWT can be exposed to high thrust loads on the rotor. The thrust load act s parallel to the rotor shaft and has a maximum value. The trust coefficient is equal to 0,5 by normative. Load case E: Maximum rotational speed The centrifugal load in the blade root FZB and the shaft bending moment M SHAFT due t o centrifugal load and rotor unbalance shall be calculated. The maximum possible rotor speed is directly relat ed to the maximum rotational speed revolutions. Load case F: Short at load connection In the case of a direct electrical short at the output of the SWT or internal short in the generator, high moment is creat ed about t he rotor shaft due to the short circuit torque of the alternator. In the absence of any values proven to be more accurat e, tw o times the QDESIGN is to be taken as the short circuit torque acting on the generat or shaft. In the absence of any values proven to be more accurate, G shall be 2,0. ENAIR ENERGY S.L. CIF- B54483656 C/Campello,19 Castalla (Alicante) +34 96 556 00 18 ENAIR ENERGY S.L. info@enair.es - www.enair .es Load case G: Shutdown (braking) In the case of w ind t urbines w ith a mechanical or electrical braking system in the drive train, the braking moment can be greater than the maximum driving moment. In these cases, the braking moment M brake, derived from testing or calculations, shall be used in the design calculations of the SWT. The maximum shaft torque is assumed to be equal to the brake plus the design torque (thus assuming that the brake is applied w hile t he generator still delivers design torque). Mbrake shall be multiplied by the gearbox ratio if the brake is on the high speed shaft. Load case H: Parked wind loading In this load case, the w ind turbine is parked in the normal w ay. The loads on t he exposed parts of the SWT shall be calculated assuming w ind speed of V e50 The maximum tow er bending moment shall be calculated using the thrust force. The drag or lift force on t he tow er and nacelle need to be t aken int o account as w ell. For free standing tow ers the maximum bending moment w ill occur at the tow er base. For guyed tow ers, the maximum bending moment w ill occur at the upper guy w ire attachment. Load case I: Parked w ind loading, maximum exposure In the case of a failure in the yaw mechanism, the SWT can be exposed to the w ind from all directions. Thus, for design purposes, the forces on the SWT blades, nacelle, tow er, and t ail (if applicable) shall be calculated for all possible exposures including w inds from the front, side or rear of the rot or. Load case J: Transportation, assembly, maintenance and repair The manufacturer shall consider loads on the turbine system caused by t he transportation, assembly, installation, and maintenance and repair of the system. Examples of such loads are: – gravity loads on turbine during transportation in other than upright position – loads caused by special installation tools – w ind loads during installation – loads introduced by hoisting the turbine onto the foundation – loads on a tilt up tow er during erection – load on a support structure from climbing it ENAIR ENERGY S.L.

According to IEC 61400-2 safety factors for this machines must be higher than 9 if the material properties are not charact erized but if the mat erial is full characterized as w e have made w ith ours the safety factor must not be less than 3. We have made the choice to full characterize the materials and despite of that w e also get higher safety fact ors. In the next tables the comparison betw een the safety factors w hich w ere obtained and the ones w hich are needed is done.
