Research on Solar Thermal Power Generation System Based on Tower Slot Coupling

建立了一种新型塔槽耦合太阳能热发电系统,对系统进行了典型年8760 h的模拟计算,得出系统年平均光热效率为40.41%,年平均发电效率为16.34%,年发电量为410GWh。对系统进行单因素分析,结果表明:新型塔槽耦合系统具有稳定性及灵活性,可降低电站非计划停运率,且当纬度低于约36°时,塔槽耦合系统年平均发电效率和发电量均高于塔式与槽式;当电站容量大于100 MWe时,塔槽耦合系统年平均发电效率以及发电量明显高于塔式与槽式,具有技术优势以及开发前景。

A tower slot coupling solar thermal power generation system was established.The typical solar year 8760-hour simulate computation demonstrates that the annual average solar collection efficiency of the system was 40.41%,the average annual power generation efficiency was 16.34%,and the generating output was 410 GWh.The result of single-factor analysis for the system showed that the tower slot coupling solar thermal power generation system had higher stability and flexibility,also it could reduce the unplanned outage rate of the power station.When the latitude below 36 degree or the power plant capacity was more than 100 MWe,the annual average power generation efficiency and generating output for this new-type system was higher than the tower system and trough system obviously.
