BEIJING, April 11 (Xinhua) -- China on Thursday voiced firm opposition to the European Union's (EU) subsidy investigations on Chinese wind turbine suppliers, calling such a move as "typical protectionism." China has lodged serious representations to the European Commission on the move, Ministry ...
The experiments on both test-bench and wind turbine gearbox fault diagnosis demonstrated that SSMPN is more effective than the comparable methods under the same situation. 4 被引用 · 1 笔记 引用 Asymmetric coordinate attention spectral-spatial feature fusion network for hyperspectral image ...
near-surface temperature, wind speed, boundary layer height, etc. Accumulation of atmosphere pollutants over a long period can lead to changes in regional climate factors6,7,8. Research on the synergistic benefits of air pollution and climate has garnered significant attention...
Among these issues change in the loads and power production due to icing have some priority. Aerodynamic characteristics of the wind turbine are affected from the first stage of icing even with small amount of ice while structural properties are affected after some ice accumulation. In this wo...
Aerodynamic powerThe wind rotor tilt angle is an important parameter on the design of wind turbine. This paper investigates its effects on aerodynamic power of wind turbine by using the parameters of NERL 5MW reference wind turbines. A two-dimensional wind speed model including modified tower ...
Results show that the energy efficiency and GHG emission per energy output of the system are 0.034MJ/MJ and 0.002kgCO2-eq/MJ, respectively. Compared with other power generation systems, wind power is more competitive in terms of both energy savings and GHG emission reduction. If wind turbine ...

The second technical feature describes the frequency characteristics of the output voltage and current of the offshore wind turbine, including DC, low-frequency AC, power-frequency AC and medium-frequency AC. The third technical feature describes the power transmission modes adopted by the offshore ...
Corrosion Contamination at Leading Edge Corrosion and contamination at the leading edge of wind turbine blades is one of the key problems in wind power production, as shown in Figure 8. Erosion and contamina- tion at the leading edge of the blade results in an increase in the resistance co...
Therefore, this paper proposes an optimal operation strategy of VPP participating in power grid dispatching and ancillary services based on output evaluation criteria. Considering the uncertainty of wind turbine (WT) and PV outputs, their weak ability for adjusting active power and the characteristics ...
