The present invention mainly relates to a support system, but is not limited thereto; in particular, the present invention relates to a support system and a wind power generation device including the same.

In the modern era where environmental awareness is gradually increasing, renewable energy, such as solar power generation, wind power generation or biomass power generation, has become an important trend that cannot be ignored; among them, wind power generation is a key development project.

Evaluation method

The present invention uses platform stability specifications and anchor cable stability specifications as evaluation methods to determine whether the support system has high stability and safety to comply with international standards.

The aforementioned platform stability specifications can be divided into Surge (longitudinal movement) direction stability specifications and Pitch (pitch) direction stability specifications. Among them, the Surge direction stability specification is that according to COREWIND D2.1 in the horizontal movement direction, the maximum drift distance in water depths of 60 to 100 meters is 30 meters; the maximum drift distance in water depths of 100 to 250 meters is 30 to 250 meters. 60 meters; the maximum drift distance in water depths greater than 250 meters is 5 to 12% of the water depth.

The pitch direction stability specification is that, according to DNVGL-RP-0286, under normal operation (such as DLC 1.2, 1.6), the average tilt condition of the floating fan during operation shall not exceed 5 degrees in the time series, and the maximum value shall not exceed 5 degrees. exceeds 10 degrees; and under shutdown conditions and extreme conditions (such as DLC6.1, 6.2), the inclination angle of the floating fan without operation shall not exceed 15 degrees.

Please refer to Table 1. According to the analysis results, it can be concluded that the data results in the surge direction and the pitch direction all fall within the specification requirements. Therefore, the overall stability of the platform of the support system of the present invention is sufficient to resist the influence of extreme external conditions.

Table 1 Maximum and minimum values of platform horizontal movement and fan tilt angle variables minimum value maximum value maximum value minimum value Surge (meter) -4.8 13.2 18.4 Pitch (degree) -3.71 4.75 8.46

The aforementioned anchor cable stability specifications are, according to DNGVL-OS-E301, considering extreme conditions, after the support platform and anchor cable are coupled, the obtained anchor cable tension must be less than the minimum breaking force (MBL). In the anchor cable tension analysis, a float B (please see Figure 1c and Figure 2c) is set on the anchor cable to ensure that it is always in a tensioned state, and the fairlead is used as the analysis point because the displacement of the anchor cable here The change is the largest, and this area also bears the maximum tension of the entire anchor cable, and anchor cable breakage often occurs here. Therefore, the present invention uses the fairlead as the evaluation location for the minimum breaking force (MBL).

Figure 5 is a time sequence diagram showing the tension of an anchor rope according to an embodiment of the present invention. The horizontal axis is time and the vertical axis is tension. Please refer to Figure 5. According to the analysis results, it can be found that the anchor cables are continuous and will not break when measured. Therefore, the anchor cable configuration of the support system of the present invention is sufficient to resist the influence of extreme external conditions.
