Definitions

  • the present invention relates to the in situ repair of damaged wind turbine blades.
  • any operational down time of the WTG has a direct effect on the cost efficiency, annual energy production (AEP) cost and ROI, therefore any repairs required should be kept to a mijiimum along with the time taken to complete the same.
  • Turbine blades are the primary elements of WTGs. Most wind turbines start operating at a speed of 4-5 metres per second and reach maximum power at about 15 metres per second. Most modern turbine blades consist of an upper and lower composite shell with inner reinforcement, plus a circular foot section for mounting on the pitch-bearing (a pitch bearing is used by a pitch regulation device to maximise energy generation and protect the blades from being overpowered in excessive wind conditions).
  • turbine blades are manufactured in a highly specific process using composite material within the design constraints of achieving specified structural requirements.
  • the manufacturing process of turbine blades typically involves bonding a suction side shell and a pressure side shell together at bond lines all along the trailing and leading edges, root and tip of the blade.
  • the bond lines are generally formed by applying a suitable specification of bonding paste or compound along the bond line with a minimum designed bond width between the shell members to form a close fit. These bonding lines are a critical design constraint of the blades.
  • Blades operate in demanding environmental conditions, which include extreme weather and surface "bombardment" with sand and dirt particles.
  • a significant number of turbine blade field failures are bond line related, particularly leading edge failures, this may often be triggered by the erosion of the leading edge resulting in moisture intrusion. Separation of the bond line along the leading edge of an operational turbine blade can result in a catastrophic failure and damage to the wind turbine.
  • the leading edges of blades are highly susceptible to erosion in the field conventional.
  • Leading edge bond configurations are also highly susceptible to erosion in the field due to the conventional manufacturing practice of locating these bond lines in the centre of the leading edge, which results in costly and expensive field repairs; such repairs are costly and time consuming in remote onshore locations, however, in offshore locations the requisite time and costs are considerably greater.
  • blade defects and damage can occur through impact (e.g. birds), ice, lightning, manufacturing related weaknesses or overstress due to turbulence or extreme wind forces, component related failure such as pitch regulation devices, UV, salt and insect build up.
  • the typical process of repairing a blade defect will involve the use of a ceramic (or other) abrasive grinder to remove sufficient composite material to reveal the unaffected composite structure beneath the defect, and to determine the extent and depth of the issue.

  • Figures 9-11 show perspective views of the joins between adjacent sections.
  • Wind turbine blade material is inherently vulnerable to erosion, but the sector of the blade which is particularly susceptible to this damage is the leading edge. Instead of repairing leading edge erosion numerous times during blade design life it's much more efficient to replace the leading edge material in this sector with a more durable material.
  • the present invention provides the manufacture and installation of modular leading edge component sections, which would be used to effect repairs to significant leading edge damage more rapidly and cost effectively than current procedures permit.
  • the use of sections removes the need to repair each individual defect within the same area or section of the blade, by facilitating the removal of entire damaged leading edge sections which would then be replaced by modular leading edge component sections.
  • the proposed method of using modular leading edge component sections would require the removal by a cutting process of a longitudinal section of the leading edge to a specified depth and length, subsequent to which the modular leading edge component section would be adhered to the prepared shell surface. This modular repair process would be considerably faster and require considerably less time to complete, which is a major limiting factor in determining access to wind turbines and in particular off shore wind turbines.
  • leading edge protection (LEP) coatings or tapes can be incorporated onto the blades. It's possible to apply LEP either during the manufacturing process (i.e. in mould/casting) and post manufacture in a controlled environment, which maximises operational durability; infield/situ.
  • Figure 1 shows a conventional wind turbine generator 2 comprising a nacelle 4 mounted on a tower 6.
  • the nacelle includes a hub 8 from which the blades 10 depend.
  • the turbine can be situated on land (on-shore) or offshore, either by anchoring to the sea bed or positioning on floating platforms.
  • a plan view, perspective view and cross sectional view of a turbine blade 10 is shown in figures 2a-2c respectively.
  • the root portion 12 of the blade is attached to the hub 8 and from the root 12 the rest of the blade extends in a substantially linear manner to the tip 14.
  • the leading edge 16 meets the wind and is the part that typically sustains the majority of wear and/or damage the blade is subject to.
  • the trailing edge 18 sustains relatively little damage compared to the leading edge.
  • the blade itself is usually formed from an upper shell 20 and a lower shell 22 attached together with adhesive to form an internal cavity 24.
  • the internal blade spine or beam is formed one or more shear webs 26 and spar caps 28.
  • Figure 3 shows a cross sectional view along the longitudinal axis of the blade.
  • the bond line 30 formed from the attachment of the upper 20 and lower 22 shells is located substantially centrally along the leading edge 16 of the blade. As discussed, it is this area that is damaged 32 the most from erosion, impact, etc. and considerable damage can be made if OEM bond line 30 is exposed and is open to the elements.
  • Figures 4a-4d show erosion of the leading edges 16 of turbine blades 10 from use of around one year in figure 4a, two years in figure 4b, around ten years in figure 4c to over ten years in figure 4d.
  • the figures illustrate that is usually the outer layers of the blade that are stripped or eroded through use to expose the support material underneath.
  • Figure 5c and 5d shows a transverse cut line 34 which is made perpendicular or orthogonal to the OEM bond line 30, to remove at least part of the leading edge of the blade, and in particular the part that includes the damage.
  • the cut can be made with a saw, chainsaw, grinder, angle grinder, circular saw and/or the like capable of cutting through the composite shell of the blade.
  • Figure 5c shows the cross sectional view once the damaged edge portion has been removed and one or more prefabricated modular sections 38 inserted into place. It can be seen that the OEM bond line 30 is covered, effectively by being capped and a new bond line runs orthogonal to the OEM bond line. Thus, in the event the modular section is damaged at the leading edge, the OEM bond line will not be exposed.
  • each modular section 38 precisely resemble the original OEM specification and form so each modular section precisely mirrors the curvature of the leading edge of each blade along each damaged section to be replaced or repaired.
  • These modular sections can be kept in stock and transported on site as required. It can be seen that usually in order to fit the modular sections, straight lines are required to be cut into the blade which significantly reduces the time an operator has to spend on repair and thus reduces the length of time the turbine is out of operation.
  • Figure 9 shows how the repair section 38 itself can be provided in a number of modules 38a-38c.
  • the prefabricated modular section 38 or plurality of sections 38a- 38d can conform to the original curved shape or profile of the outer shell or skin layers.
  • a robotic arm removes a strip 42 of the outer layer of the blade leading edge.
  • the removal is usually by cutting or grinding a channel thereby removing a substantially linear section of the leading edge.
  • the edges of the strip 42 can include steps, lips and/or the like to improve the bonding between the channel and the repair section 38.
  • the edges of the channel are scarfed to form strong joints with a relatively small seam.
  • FIG 5 around 2.5 mm of the leading edge outer layers are removed.
  • figure 6 around 0.2 mm is removed.
  • the damaged portions are removed by machining or cutting away only the outer one or two layers of the blade material.
  • the prefabricated strip 38 is overlaid and given the thinness of the repair, no joint formations are required.
  • Figures 8a and 8b show an embodiment where no machining or cutting is performed and a precast or prefabricated section of 3-4 plys of thickness is applied over the damage.
  • Figures 9, 10 and 11 show examples of the different types of joints possible between adjacent prefabricated sections or modules 38a, 38b.
  • Figures 9 and 11 show insertion and dovetail joints respectively.
  • Figure 11 shows lap or splice joints.
  • leading edge erosion (LEE) repair utilises fibreglass matting, whereby for each make and model of blade, there would comprise multiple layers of specified uniaxial, biaxial and/or triaxial fibreglass matting (or other such specification of matting—such as thermoplastic materials, or other materials which would be suitable for this purpose) which when bonded together using resin/hardener cure to form a hard shell.
  • the hardness of the finished shell could vary according to need and preference.
  • Fibreglass matting is typically specified according to a number of different parameters, e.g ⁇ the weight per square meter (gsm), direction of fibres, flexibility, strength, combinations of materials, quality, etc.
  • This LEE repair solution we have developed uses such multiple layers as correspond, closely or exactly, to the leading edge design and manufacturing specification of each particular make and model of wind turbine blade. In certain circumstances it may be preferable to use other multiple layers which do not correspond or which are fundamentally different from the leading edge design and manufacturing specification.
  • the selection of materials for each make and model may vary widely. In one embodiment the particular materials will not be pre-cured.
  • Adhesives are available in a number of specifications and forms/types— e.g. paint on, spray on, catalyse, peel off, etc.
  • an at least initially inert sheeted version of the specified adhesive which may be catalysed with high heat and moderate pressure over a relatively short period of time. Therefore, for a given blade the requisite combination of matting, resin/epoxy and adhesive will be rolled together for convenient transportation to the repair site then unrolled, cut to fit as required, then cured into position.
  • An important aspect of this invention is the capability to scan in 3D the leading edge surface of the blade to generate CAD data, which then facilitates comparison between the LE blade surface geometry of a new blade to then determine the extent to which the cutting path and depth require to be executed in order to ultimately restore aerodynamic performance, once the new module is installed, by rejuvenating the surface geometry.
  • the results of this computer generated calculation will uniquely dictate the precise machining process required for each and every LE to be repaired.
