| 摘 要： | 基于我国部分风电场的统计数据,分别利用概率分布、相关性分析对风电场的风电特性和规律进行研究。研究表明:风力发电量在全年的分布,可用三参数广义极值分布模型进行描述,风电的概率分布可以作为风电场性能的衡量指标之一,从分布情况可以得出其风电分布的大致规律;风电削峰后损失的大小以及对外部电源依赖的程度,可以作为风电场性能的另一个评价指标;日风电量之间属于微相关,风电预测需结合气象、气候、地形资料等进行。

| Abstract: | Wind power is greatly restricted by grid connection,and can be used without connection with grid according to demand features of the end users.The wind power characteristics are analyzed based on statistics from a few of wind farms of China.The generalized extreme value distribution can be used to describe the electricity of wind power in China,thus the general characteristics of wind power can be obtained.Probability distribution of wind power can be used as one of the indicators to evaluate performance of... |
