Abstract: It is a wind and solar turbine that produce energy with wind and solar power by combining polymer solar panels. The wind turbine fans are spherical, and its lateral cuts are indeed interconnected blades next to each other, which are connected to the vertical axis at a distance of 4 cm from each other. A set of magnets with like poles is installed on the cut beginning and end of each fan. Therefore, they form a full circle together. Placing the plates of the magnets with like poles along the way also reduces friction, and fans move easily with low wind pressure (7 to 12 km). The highest fan in the turbine, in addition to the generator, has another engine for double acceleration. According to the data analysis gained from the anemometer and speedometer, the computer will be able to increase the fan speed by inducing regular motion pulses.

Such condition monitoring further includes mathematically extracting one or more such subset signals from the at least one time-series electrical output signal of the generator, and associating one or more such subset signals with one or more wind turbine components. A fault threshold value for each such one or more subset signals may be determined, and the one or more such subset signals are compared to such fault threshold value. Based on such association and comparison, the condition of such a wind turbine component of the plurality of wind turbines is determined.

Abstract: Disclosed are a method and apparatus for detecting a yaw-to-wind abnormality. The method includes: acquiring a wind direction deviation angle within a specified time period; calculating a power performance index, wherein the power performance index is a dimensionless number used to characterize power generation performance of a wind turbine; determining an optimal wind direction deviation angle based on the power performance index; determining a current wind direction deviation angle according to probability distribution of the wind direction deviation angle; and if a difference between the optimal wind direction deviation angle and the current wind direction deviation angle is greater than a preset threshold, determining that a yaw-to-wind abnormality is detected. Compared with the related technology in which yaw-to-wind detection is performed through a power fitting curve, in the technical solution according to the embodiments of the present disclosure, a power index is directly used, which avoids the problem of poor power curve fitting effect and improves the accuracy of yaw-to-wind detection.

Abstract: A wind power generation apparatus (1000) includes a rotating shaft (200), a wind power generation device (100) assembled to the rotating shaft (200), and an acceleration restriction mechanism (500). The wind power generation device (100) includes a drag blade (11) fixed on the rotating shaft (200), an inner housing (12) connected to an outer edge of the drag blade (11), and an outer housing (21) sleeved around the inner housing (12). The acceleration restriction mechanism (500) includes a plurality of swing arms (511) pivotally connected to the inner housing (12) and a metal ring (520) fixed on the outer housing (21). A magnetic portion (5112) of each swing arm (511) is movable relative to the inner housing (12) from an initial position to an acceleration restriction position. When the magnetic portion (5112) of each swing arm (511) is at the acceleration restriction position, the magnetic portion (5112) at least partially covers the metal ring (520), so that the metal ring (520) generates an eddy current limiting a rotating acceleration of the drag blade (11).
