复杂地形风电场后评估研究

Post-Evaluation of Wind Farms at Complex Terrains

摘要: 为提高风电场设计水平和降低风电企业投标经济风险，有必要对复杂地形风电场项目的风能资源进行后评估。本文首先确定了风电场后评估的技术指标。接着讨论了技术指标的相关影响因素。最终，基于某工程实例，采用后评估方法对该风电场设计阶段与运行阶段相关参数进行对比及分析，结果表明：风电场运行指标与设计指标最大误差不超过3.1%，本文提出的相关折减系数具有较好地适用性，可以为风电企业和投资方提供参考。

Abstract: Wind energy post-evaluation for the wind power projects of complex terrain can improve the design level of wind power plant and reduce finical risk for the bids. In this paper, technical index was firstly identified for the post-evaluation of wind energy. Moreover, the effect factors on the technical index were discussed. Finally, the post-evaluation method was adopted in a practical project to compare and analyze the relative parameters between the design stage and operated stage. The results show that the maximum error between the two stages is not greater than 3.1%, indicating that the reduction factors proposed in this paper is suitable for wind power industry and investment company.
