Definitions
- the present invention relates to suppression of shaking of a transformer used in a floating offshore wind power generator.
- floating offshore wind power generators have had problems with maintenance methods based on fluctuations, vibrations, and inclinations caused by wave winds.
- the wave wind is strong and it is always exposed to the wave wind in the front, rear, left, and right, so the fluctuation due to the inclination has become a concern for the floating offshore wind power generator.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2003-252288
- Patent Document 2 Japanese Patent Application Laid-Open No. 2011-89468
- Patent Document 1 as a floating-type foundation structure for offshore wind power generation, a cylindrical main floating body that is long in the axial direction and a plurality of sub-floating bodies provided integrally with the main floating body so as to surround the main floating body are provided. Prepare and suppress upset.
- Patent Document 2 describes that a secondary battery is disposed below a water line so that the attitude of the wind power generator is stabilized by its weight.
- transformer screw looseness, coil position deviation, and oil-filled transformer may cause air bubbles and cause breakdown due to partial discharge, which may cause transformer failure. .
- Patent Document 1 since it is necessary to include a plurality of sub-floating bodies provided integrally with the main floating body so as to surround the main floating body, there is a problem that the structure is complicated and the manufacturing cost increases. there were. Also in Patent Document 2, it is necessary to provide a secondary battery, and similarly, there is a problem that the manufacturing cost increases.
- Patent Documents 1 and 2 can suppress the fluctuation to some extent, the influence of the fluctuation cannot be reduced to zero.
- there is no description about a floating offshore wind power generator equipped with a transformer and no consideration is given to suppression of swinging of the transformer.
- FIG. 1 is a schematic configuration diagram of a floating offshore wind power generator.
- 1 is the whole floating offshore wind power generator
- 2 is a blade
- 3 is a nacelle
- 4 is a generator
- 5 is a tower
- 6 is a sea surface
- 7 is a transformer
- 8 is a power transmission cable.
- the floating offshore wind power generator 1 is floated on the ocean, floats upright on the ocean, and is connected to an anchor with a mooring chain (not shown).
- AC power is generated by the generator 4 disposed in the nacelle 3, the power is boosted by the transformer 7 disposed in the tower 5, and is transmitted by the power transmission cable 8.
- the reason for boosting with a transformer is that the current can be kept low by increasing the voltage, so that the current can be safely transmitted at a low current, and the loss during power transmission is suppressed by a low current value.
- FIG. 2 is a diagram for explaining the balance of the floating offshore wind power generator.
- B indicates a buoyancy and G indicates a center of gravity. Buoyancy works upward from the buoyancy and gravity works downward from the center of gravity.
- FIG. 2 shows a balanced state.
- the illustrated floating offshore wind power generator has a spar type floating structure.
- the spur type is a structure that ensures static stability by always keeping the center of gravity below the center of gravity.
- Fig. 3 shows the balance when the floating offshore wind turbine generator is tilted.
- the floating core moves from B to B ′.
- a portion where the vertical direction of B ′ intersects with the extension line of BG is called an eccentricity (M) (metacenter). This tilt is the center at which the floating offshore wind turbine generator tilts, and always starts tilting around the tilt.
- M eccentricity
- FIG. 4 is an explanatory diagram of this embodiment.
- the floating offshore wind power generator tilts around the tilt, so the transformer 7 is placed at the tilt.
- transformer screw loosening and coil misalignment due to fluctuations, and oil-filled transformers may cause air bubbles and cause breakdown due to partial discharge, etc. Can be eliminated.
- the maximum tilt angle of the floating offshore wind power generator is about 15 °.
- the rotating diameter of the blade is 80 to 125 m
- the total length is about 170 m, which exceeds 100 m, and more than half of the total length is submerged in the sea.
- the transformer is arranged in the vicinity of the tilt, but the arrangement can be limited from the moment tolerance of the transformer, the seismic design strength, and the like.
- the transformer when focusing on the coil support strength of the transformer, if the coil support strength Y and the coil weight Z are set, the transformer should be designed with the coil support strength Y satisfying the relationship Y> 2.68 * Z. As a result, it is possible to optimize the measures for shaking the transformer and reduce the cost. In addition, damage to the transformer can be minimized. For this reason, a reduction in transportation costs due to transformer maintenance can be expected.
