摘要
在铁路弓网上方安装光伏发电系统的方式即光伏化弓网,其能为铁路沿线提供电能供应,并减少恶劣天气对铁路运营的影响。分析了采用光伏化弓网时,雨雪、覆冰、横向风、接触线硬点对铁路线造成的影响;对光伏发电系统的主要设备进行对比选择并估算发电量,简算列车风对光伏组件的影响;并探讨如何在不影响铁路运营的情况下,对已有的铁路弓网进行光伏化改造。分析结果显示:光伏化弓网能够降低雨雪、覆冰、横向风、接触线硬点对铁路运行的影响,且易于安装和维护,具有较高的实用价值。
PV pantograph-catenary is the way to install PV power generation system above the railway pantograph-catenary,which can provide power supply along the railway and reduce the impact of bad weather on railway operation.This paper analyzes the impact of rain,snow,ice,transverse wind and catenary hard spots on the railway line when PV pantograph-catenary is used.Compare and select the main equipment of the PV power generation system,estimate the power generation capacity,and simply calculate the impact of the train wind on the PV modules.It also discusses how to carry out PV transformation of existing railway pantographcatenary without affecting railway operation.The analysis results show that the PV pantograph-catenary can reduce the impact of rain,snow,ice,transverse wind and catenary hard spots on railway operation,and is easy to install and maintain,with high practical value.
