风电场发电量后评估的指标评估方法探讨

风力发电机组的发电量指标是体现风电场运营的重要指标之一。对风电场项目后评价应集中于发电指标评价,由于发电量与风能资源联系紧密,而风能是随机变化、无法预估的,对发电量指标的评估有一定难度。针对此问题,提出对风电场实际运行期的发电量进行代表年分析订正的方法,对发电量进行评估。通过风电场实施前与风电场建成后的实际发电量对比,对风电场实际运行期的发电量进行代表年分析订正后,分析产生偏差的各种原因,最后根据风电场的实际参数,针对各种影响提出了调整建议,以使评估发电量更符合实际情况,为以后风电场可研设计提供参考。

Discussion on the Post-Evalution Method Step of Wind Farm Generation

Wind turbine generating capacity indicator is one of the important indicators reflecting the post-evaluation process of wind farm operator. Wind energy randomly changed, which principally influences the power generation in wind farm. The situation of wind could not be given an exact prediction. Therefore, it is really difficult to evaluate the generation quantity depending on wind. In this article, confronting this problem, the solution could be demonstrated that the actual generation quantity of operating wind farm would be calibrated with the representative year, and theoretical generation could be evaluated.By contrasting wind farm operation with result of feasible research, and adjusting accurately the electricity generation on operation period with representative year. It can be analyzed and summarized the practical effects on generation by some factors, according to the present situation of wind farm, it can be offered some advisements to resist these adverse influences, after the adjustment generating capacity more tally with the actual situation, as references for next feasibility research designing.
