연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A method for removing a rotor blade from a wind turbine, the method comprising: installing a blade sock around an outer perimeter of the rotor blade at an intermediate location defined between a blade root and a blade tip of the rotor blade;coupling a support cable to the blade root via a threaded rod extending through a root bolt opening defined through a root end of the blade root, wherein the threaded rod extends from the root bolt opening through a corresponding bolt hole defined through a pitch bearing of the wind turbine;lowering the rotor blade relative to the hub using the support cable such that the rotor blade is spaced apart from the hub by an initial vertical distance;coupling at least one pulley cable between the rotor blade and a winch located on or adjacent to a support surface of the wind turbine using at least one pulley;moving the at least one pulley cable relative to the at least one pulley to lower the rotor blade relative to the hub beyond the initial vertical distance;applying a force through the blade sock as the at least one pulley cable is moved relative to the at least one pulley in order to control an orientation of the rotor blade relative to at least one of a tower of the wind turbine or the support surface; andfurther lowering the rotor blade to a location on or adjacent to the support surface. 2. The method of claim 1, further comprising: lifting the blade sock relative to the support surface to the intermediate location; andtightening the blade sock around the rotor blade at the intermediate location using a cable coupled to the blade sock. 3. The method of claim 2, wherein the blade sock includes a self-tightening sock strap configured to be coupled to the cable, wherein tightening the blade sock around the rotor blade comprises applying a force through the self-tightening sock strap via the cable in order to tighten the blade sock around the rotor blade. 4. The method of claim 1, wherein a barrel nut is mounted at least partially though the blade root, wherein the threaded rod is coupled to the blade root via the barrel nut. 5. The method of claim 1, further comprising: installing a cable translation device within the hub; andoperatively associating the support cable with the cable translation device such that the support cable extends from the threaded rod through a portion of the cable translation device. 6. The method of claim 1, further comprising: installing a cable translation device within the hub adjacent to the pitch bearing; andinserting the support cable through at least a portion of the cable translation device. 7. The method of claim 6, further comprising operating the cable translation device such that the support cable is incrementally lowered through both the cable translation device and the pitch bearing in order to lower the rotor blade relative to the hub. 8. The method of claim 6, wherein the cable translation device comprises a fluid-driven actuator including a cylinder and a hollow piston configured to be actuated and retracted relative to the cylinder in order to allow the support cable to be lowered through the hollow piston. 9. The method of claim 6, wherein the support cable includes a plurality of lugs spaced apart along a length of the support cable, further comprising: installing a stop block around the support cable directly above, the cable translation device;lowering the support cable using the cable translation device such that the support cable passes through the stop block;removing the stop block from the support cable when an adjacent lug of the plurality of lugs is positioned directly above the stop block; andrepositioning the stop block around the support cable at a location above the adjacent lug. 10. The method of claim 1, wherein the threaded rod defines a length that is the same as or less than a length defined by a plurality of root bolts coupled to the blade root. 11. The method of claim 1, wherein the at least one pulley comprises at least one blade pulley and at least one up-tower pulley, the method further comprising: coupling the at least one blade pulley to a blade root of the rotor blade; andcoupling the at least one up-tower pulley to an up-tower component of the wind turbine; andpositioning the pulley cable around the at least one blade pulley and the at least one up-tower pulley. 12. The method of claim 1, wherein applying the force through the blade sock comprising controlling an amount of tension in a cable coupled to the blade sock in order to control the orientation of the rotor blade relative to the tower or to rotate the rotor blade into a generally horizontal position relative to the support surface. 13. A method for lowering a rotor blade relative to a hub of a wind turbine, the wind turbine including a pitch bearing coupled to the hub, the method comprising: installing a plurality of cable translation devices within the hub, wherein each of the plurality of cable translation devices comprises a cable hoist;inserting a plurality of support nuts through a circumferential wall of a blade root of the rotor blade at locations spaced apart from a root end of the blade root;installing a plurality of support cables in operative association with the plurality of cable translation devices;coupling each of the plurality of support cables to one of the plurality of support nuts; andoperating the plurality of cable translation devices such that the plurality of support cables are moved relative the plurality of cable translation devices in a manner that causes the rotor blade to be lowered relative to the hub. 14. The method of claim 13, further comprising: removing a plurality of barrel nuts from the blade root of the rotor blade; andreplacing each of the plurality of barrel nuts with one of the plurality of support nuts. 15. The method of claim 13, further comprising coupling a threaded member to each of the plurality of support nuts, the threaded member extending through both a root bolt opening defined through a root end of the blade root and a corresponding bolt hole defined in the pitch bearing. 16. The method of claim 15, wherein the threaded member comprises one of a threaded cable stud of a secondary support cable, an alignment pin or a root bolt of the wind turbine. 17. A method for removing a rotor blade from a wind turbine, the method comprising: coupling a support cable to a blade root of the rotor blade, wherein the support cable extends from the blade root and into a hub of the wind turbine;lowering the rotor blade relative to the hub using the support cable such that the rotor blade is spaced apart from the hub by an initial vertical distance;coupling a first blade pulley and a second blade pulley to the blade root;coupling at least one up-tower pulley to an up-tower component of the wind turbine, wherein the at least one up-tower pulley is vertically aligned with at least one of the first blade pulley or the second blade pulley;coupling at least one pulley cable to the first and second blade pulleys and the at least one up-tower pulley, the at least one pulley cable extending from the rotor blade to a location on or adjacent to a support surface of the wind turbine; andmoving the at least one pulley cable relative to the first and second blade pulleys and the at least one up-tower pulley to lower the rotor blade relative to the hub beyond the initial vertical distance. 18. The method of claim 17, further comprising: installing a blade sock around an outer perimeter of the rotor blade at an intermediate location defined between a blade root and a blade tip of the rotor blade;applying a force through the blade sock as the at least one pulley cable is moved relative to the first and second blade pulleys and the at least one up-tower pulley in order to control an orientation of the rotor blade relative to at least one of a tower of the wind turbine or the support surface.
