摘要
采用CFD软件Meteodyn WT分析某山地风电场建设前后发电量损失情况。在山地风电场建设中,吊装平台对风力机海拔高度造成不同程度降低,进而使风力机轮毂处风速降低,导致风力机发电量损失。研究表明,该风电场5台风力机在建成后受吊装平台影响,海拔高度降低最大11.40 m、最小7.80 m、平均9.34 m;受海拔高度降低影响,在风力机轮毂处风速降低最大0.030 m/s、最小0.010 m/s、平均0.018 m/s;风电场发电量每年损失287.390 MWh,单台风力机发电每年损失最大84.090 MWh、最小40.520 MWh。研究结果可为同类型山地风电场建设前后发电量损失研究提供参考。
It uses CFD software Meteodyn WT to analyze the power generation loss before and after the construction of a mountain wind farm.In the construction of the mountain wind farm project,the lifting platform reduces the altitude of the fan to cause different degrees,then the wind speed at the wheel hub,resulting in the loss of wind turbine power generation.The researches show that five wind turbines of the wind farm are affected by the lifting platform after construction.The altitude of the maximum and minimum altitude decreases by 11.40 m,7.80 m,and 9.34 m on average.Under the influence of altitude reduction,at the hub of the wind turbine,the wind speed decreases by 0.030 m/s at the maximum,0.010 m/s at the minimum,and 0.018 m/s on average.The power loss of the whole wind farm is 287.390 MWh/year,and the maximum power loss of a single wind turbine is 84.090 MWh/year and the minimum is 40.520 MWh/year.
