风光互补发电系统的优化设计Ⅱ匹配设计实例

OPTIMALLY DESIGN OF PV/WIND HYBRID SYSTEM Ⅱ.A CASE STUDY

根据风光互补发电系统优化设计的CAD方法编制了相应的匹配计算程序,并把该程序应用于一假定安装在香港横澜岛上的风光互补发电系统的优化设计。利用香港天文台提供的1989年全年每小时实测的太阳辐射、风速和温度数据以及全年负载用电分布等数据给出了满足两种供电可靠性要求即全年功率供给亏欠率LPSP分别等于0 1和0 01的优化了的系统配置。文章还比较并讨论了这两种优化的系统配置每小时、每日、每月和全年的性能表现。

According to the CAD method for optimum sizing of PV/wind hybrid system a set of match calculation programs has been developed.Applying these match calculation programs to an assumed PV/wind hybrid system to be installed at Waglan island of Hong Kong,two optimum configurations which correspond to LPSP values equal to 0.1 and 0.01 respectively were given based on load demand and hourly solar radiation,wind speed and temperature data measured by Hong Kong Observatory in 1989.Hourly,daily,monthly and yearly performances of the two optimum configurations are also compared in this paper.
