项目后评价作为一种技术经济活动,是总结项目经验、提高项目投资效益的重要手段.在风电项目后评价中,发电量评价是区别其他项目的核心内容之一.在实际发电量评价过程中,不能仅将可研理论发电量与评价期实际发电量做简单的数据比较,应充分考虑风电场风资源的长期变化、发电量折减系数等各种因素,可采用功率曲线分析的方法深化这一评价过程,使发电量评价更具科学意义.
項目後評價作為一種技術經濟活動,是總結項目經驗、提高項目投資效益的重要手段.在風電項目後評價中,髮電量評價是區彆其他項目的覈心內容之一.在實際髮電量評價過程中,不能僅將可研理論髮電量與評價期實際髮電量做簡單的數據比較,應充分攷慮風電場風資源的長期變化、髮電量摺減繫數等各種因素,可採用功率麯線分析的方法深化這一評價過程,使髮電量評價更具科學意義.

Post project evaluation, as a technical and economic activity, is an important means of summarizing project experiences and improving project investment effciency. During the wind farm post evaluation, energy production evaluation is one of the central elements to distinguish from other projects. The annual electricity energy production (AEP) evaluation is not only the simple comparison between the theoretical AEP and the actual AEP, but also needs to consider the changes of the long-term wind resource and the reduction factors.this article gives an alternative method, called power curve analysis to improve the evaluation procedure.
