| 摘 要： | 高速铁路的运营需要大量电力供给，为缓解铁路电网压力，减少能源消耗，提出一种在高速铁路上方架设光伏组件的发电系统；对上述系统进行相关计算，量化全国设计时速超过200 km/h高速铁路线路的光伏发电潜力。研究结果表明，在中国太阳年辐射量大于1200 kWh/m2的高速铁路线架设光伏系统，年发电量超过7×104GWh，接近三峡大坝的年发电量，能有效缓解铁路电网压力；时速350 km/h的列车全速运行时，其上方4.5 m处的光伏组件表面压强分布正/负极值为140 Pa/-225 Pa，风速极值为3.5 m/s，满足光伏组件最大风载荷极限值要求，高速铁路光伏系统节能减排效益显著，并具有投资的经济可行性。

| Abstract: | The operation of high-speed railway needs a large amount of power supply. In order to alleviate the pressure of railway power grid and reduce energy consumption, a power generation system with photovoltaic modules above high-speed railway is proposed. Relevant calculations are carried out for the above systems to quantify the photovoltaic power generation potential of national high-speed railway lines with a design speed of more than 200 km/h. The results show that the annual PV power generation installed over high-speed railway lines in area of annual solar radiation greater than 1200 kWh/m2 is more than 7×104 GWh, which closes to the annual power generation of the Three Gorges Dam, and can effectively alleviate the pressure on the railway power grid. When the train with a speed of 350 km/h runs at full speed, the positive/negative value of the surface pressure distribution of the photovoltaic module at 4.5 m height is 140 Pa/-225 Pa, and the extreme wind speed is 3.5 m/s, which meets the requirements of the maximum wind load limit of the photovoltaic modules. The energy conservation and emission reduction benefits on the photovoltaic system of the high-speed railway are significant, and the investment is economically feasible. |
