地形图精度对复杂地区风电场计算结果的影响

摘要

The paper focuses on effects of the topographic map precision on calculation results of the Net AEP (Annual Energy Production) and wake value of wind farms over the rugged terrain. Typical wind farms are calculated and analyzed using different contour-line intervals and comprehensive wake models to obtain the primary laws of the map precision effect on the Net AEP and wake value of the typical wind farm. The results show that different wake models have different sensitivities to the map precision, and the result of using the PARK wake model is the maximum; maps of different precision have little effects on Net AEP and comprehensive wake value of wind farms over the rugged terrain.%主要研究了地形图精度对复杂地区风电场年净发电量和尾流值计算结果的影响,通过对典型风电场应用不同精度的地形图和尾流模型的计算分析,得出地形图精度对于风电场年净发电量和尾流值影响的初步规律,通过计算分析得出如下结论:不同的尾流模型对于地形图精度的敏感度不同,利用PARK尾流模型计算出的风电场年净发电量最大；不同精度的地形图对于复杂风电场年净发电量和尾流值的影响都不大.
