计及尾流效应和集电系统的风电场功率计算方法
摘要：
本发明公开一种计及尾流效应和集电系统的风电场功率计算方法，该方法考虑风电场内尾流效应、集电系统元件等因素，提出风电机组输出功率计算方法。步骤为：1、建立等值风电机组和集电系统的可靠性模型，并对各元件状态进行抽样；2、基于深度优先搜索法对元件进行连通性分析，得到风电机组状态矩阵；3、建立尾流效应模型，计算每台风机的风速；4、建立风速和风机出力模型，计算整个风电场的输出功率。本发明在一般只考虑风电机组故障的风电场可靠性建模的基础上，提出一种新的结合尾流效应和集电系统元件的风电场输出功率计算方法，提高了对风场输出功率计算的真实性和准确性，为之后风电场并网求解更高精度的可靠性指标奠定基础。
