today's headline Qilu one point Ji'nan newspaper
the global first segment photovoltaic Road The expressway was put into operation in Ji'nan at the end of last year. After the spring transportation peak and the snowfall, snow melting day baptism, how is the current operation of this section of the photovoltaic road? An interview with reporters found that the electricity has been connected to the charging pile to achieve grid connected power generation, which has been realized as a freeway lamp, electronic information board, snow melt agent spraying facility, tunnel and charge. The station provides power supply and other functions. Up to now, the total generating capacity is about 100 days, and the cumulative generating capacity is 87 thousand and 920 kWh.
Qilu traffic development group (Qilu) sets the small range of photovoltaic road section to Ji'nan South speed, which is the world's first expressway bearing type photovoltaic pavement test section. The total length of the test section is 1120 meters long, the length of the photovoltaic pavement is 1080 meters, the total area is 5874 square meters and the peak power of the total installed capacity is 817.2 kW. It is the first high-speed highway with high load and high flow and complex traffic in the world, and it is also an upgrade of the future transportation industry. Replacement products - the embryonic form of "super highway". Its successful operation and stable operation marked the birth of a brand-new cross boundary fusion industry.
reporter learned that the three layers of "transparent concrete photovoltaic power component insulation protection" used in this section of photovoltaic pavement, the surface and the vehicle pedestrians contact with the protection layer, the use of "transparent concrete", can carry small electric vehicle driving; the middle layer is the original layer of power generation, paving photovoltaic power generation The components can generate electricity, and the bottom layer is the insulation layer that isolates moisture below.
according to the introduction, the test section has been running more than 40 thousand vehicles daily, through the peak of the spring traffic flow and the snow and snow melting weather. It does not affect its road performance. It embodies the good carrying capacity and anti skid performance, and meets the related requirements of the highway to the road and the whole road in our country. Photovoltaic pavement components also show good durability, and there is no abnormal phenomenon due to normal traffic. Qilu traffic group has also learned about the people's driving experience, and the feedback said that the smoothness of the photovoltaic pavement is better, the driving comfort is comfortable, and there is no obvious difference between the tire and the traditional asphalt pavement.
from the power generation, the PV test section has experienced a variety of weather types, such as haze days, snowy days, rainy days and other weather types. It encountered the special condition of overhaul of the power grid and the peak of the peak in the Spring Festival during the Spring Festival. The overall power generation reached the expected and the related equipment was running well. Up to now, the total generating capacity is about 97 days, with a total generating capacity of 87 thousand and 920 kWh.
currently, the photovoltaic pavement has been realized for highway lights, electronic information boards, automatic spray facilities for snowmelt agents, tunnels and toll stations. In the future, with the upgrading of technology and the integration of related industries, the photovoltaic pavement will gradually realize the functions of electronic marking, mobile wireless charging, pavement heat melting, Internet coverage, large data integration and analysis.
