【摘要】 风能评估是风电场建设过程中的关键工作,目前采用的评估系统主要以国外的软件为主,价格昂贵,使用复杂,采用VC++和Matlab结合开发实现了风能评估系统。采用weibull分布作为风频计算模型,利用平均风速和最大风速求解A,C参数,推导出计算风机发电量的公式。接着参照国外的风能评估软件,对系统进行功能分析和模块设计,结合VC++界面友好和Matlab计算功能强大的优点,混合编程实现了风能评估系统。最后以Nordex N80和N90为实例进行计算分析,分析结果表明,自主开发的风能评估系统功能全面,跟wasp相比,更接近于实际的发电效果。更多还原

【Abstract】 Wind power evaluation is a key work in the process of wind farm construction.Currently foreign company’s expensive and complicated evaluation software is often used in our country.So here a wind power evaluation system is proposed.Weibull distribution is used to be the wind frequency calculation model,and then a new expression about the generation calculation is deducted.Then an analysis about the system application model is made and system architecture is designed.VC++ and Matlab are used to implement the evaluation system.At last,Nordex N80 and N90 are took as a calculation example to show the system’s advantages.更多还原
