光伏声屏障在城市快速路上应用可行性分析

结合石家庄市槐安路高架西延工程，在光伏声屏障常规组件和彩色组件两种方案下，分别研究了离网系统与并网系统的电气系统、发电量、全寿命周期成本、效益等，并进行了可行性分析。结果表明，在储能装置成本无法显著降低的条件下，光伏声屏障使用离网系统供照明用电经济上不可行；彩色组件光伏声屏障影响发电效率，同时成本较高，经济上不可行；常规组件光伏声屏障并网系统经济上可行，同时具有一定的社会效益。

Feasibility Analysis on Application of Photovoltaic Sound Barriers in Urban Expressway

Combined with the Shijiazhuang Huai''an Road Viaduct West Extension Project, under two schemes of conventional components and color components of photovoltaic sound barriers, the electrical system, power generation, full life cycle cost and benefit of the off-grid system and the grid-connected system are studied respectively, and the feasibility analysis is carried out. The conclusion shows that under the condition that the cost of energy storage devices cannot be significantly reduced, and it is economically infeasible to use the photovoltaic sound barriers under the off-grid systems for lightning. The photovoltaic sound barriers of colored components will affect the power generation efficiency. At the same time, the cost is higher, which is economically infeasible. The conventional components of photovoltaic sound barriers are economically feasible and have certain social benefits under grid-connected systems.
