考虑风况时序的动态尾流损失评估方法
Research on dynamic wake loss assessment method under wind condition time series
摘要
Abstract
In order to quantify the loss caused by wake effect in wind farms considering wind condition time series,a universal dynamic wake loss evaluation method was proposed and corresponding evaluation criteria were established.The method can analyze the wake velocity deficit and power loss caused by wake interference under wind speed and direction changes over time based on a three-dimensional wake model and SCADA data.A study was conducted using an onshore wind farm in Hebei Province as an example,and the results showed that wind turbines severely affected by dynamic wake accounted for 18%of the wind farm.The rational arrangement of wind turbines in radial distance helps to reduce the loss caused by wake effect.The actual output power was 86.9%of the theoretical output power at its lowest point.The wake loss of the wind farm corresponds to the"larger"level of the evaluation criteria,and the economic efficiency of the wind farm is relatively low during the summer months(June-August).Overall,the wake loss in the wind farm is relatively severe,and the research method has practical value,providing a theoretical basis for the layout and efficiency improvement of wind turbines in the wind farm.关键词
