Application of Photovoltaic Power Supply System in Medium and Short Tunnels of Yanzi Expressway
In line with the construction concept of"low carbon and environmental protection",in order to make full use of solar energy resources and reduce the later operating costs of the tunnel,the Yanzi project installed distributed photovoltaic power generation panels in two tunnels,with a total installed capacity of 217.6 kW,and adopted"mains power +photovoltaic power"power supply mode pro-vides power for tunnel lighting,monitoring and other facilities.The tunnel photovoltaic power generation system has been operating stab-ly and well since October 2020.It is expected to generate 286,000 kW·h in the first year,6.147 million kW·h in 25 years,and a total revenue of 4.918 million yuan,reducing operating costs.It saves standard coal and reduces the emission of carbon dioxide and other gases.
