The hottest Nanjing South Station photovoltaic pow

After complex coordination, Nanjing South Railway Station photovoltaic power generation Co., Ltd. and Nanjing power supply company reached a consensus yesterday: establish another transmission line to ensure and generate power before July 1. This is the first time that the South Station photovoltaic project has been idle for two years after the National Audit Office named "catalysis" on the 17th of this month

the golden roof of Nanjing South Railway Station is composed of 30000 solar cells. It is the world's largest photovoltaic building integration project, with 276.7 million yuan invested by local enterprises CEC group and Nanjing railway investment group. According to the design, the annual power generation of the project is 6million kwh. In addition to the station's own use, it can also upload electricity, which is equivalent to saving 2000 tons of standard coal per year. However, the project has not generated electricity since the opening of Nanjing South Railway Station in June 2011. After the audit of 1139 energy conservation and emission reduction projects in 10 provinces was an important reference index for quality control and utilization design, the National Audit Office criticized 44 projects by name, pointing out that "due to the failure of the parallel access equipment, the failure to pass the parallel access review and other reasons, the roof photovoltaic power generation project of Nanjing South railway station did not play the expected benefits, and it is necessary to come up with solutions as soon as possible"

why is the world's largest rooftop photovoltaic power generation project with hundreds of millions of investment a decoration? Shi Yuan, deputy general manager of Nanjing South Railway Station photovoltaic power generation Co., Ltd., explained that the overall plan near the South Railway Station is that all power systems should use cables and be implemented along the pipe holes of the road, so the cable pipe holes should be constructed synchronously with the road. The supporting road facilities around the south station have not been completed, causing that the cable channels of the photovoltaic power station have not been fully opened, and the photovoltaic power generation cannot be incorporated into the main power supply department

South Railway Station, which has been running for nearly two years, why hasn't the surrounding road supporting facilities been completed? According to relevant sources, there was a "congenital deficiency" caused by the rush period at the beginning of the construction of the South Railway Station. Now there are still a large number of earthwork that have not been cleared and transported, so the construction of roads and underground pipelines has been delayed. The construction of supporting facilities around the South Railway Station is divided into railway and local departments, which is difficult to coordinate

"in the past two years, the use efficiency of the south station roof photovoltaic power station has solved the problems of difficult manufacture and poor accuracy of the lead screw lifting device of the tensile testing machine. In order to avoid idle damage to the equipment, we have rotated and debugged the photovoltaic cells, and the generated power is connected to some electrical equipment of the south station." Jia Yangang, director of CEC, revealed that idle resources have caused great losses to investment, and the electricity used by the stations that have attracted a wide range of interest in South mxene has no income. Not long ago, Nanjing held a special coordination meeting to give the project an operating subsidy of 9million yuan. It is learned that it is impossible to build and merge transmission lines according to the original plan in a short time. The design drawings of the new line were approved by Nanjing Planning Bureau in 20 batches this month, and the construction will be carried out immediately after approval, and the time will be as early as possible

although the result has been achieved, its complex process is thought-provoking. Liu Xin, a red commentator, pointed out that the "276.7 million furnishings" of the research on porous polymer material capture and catalytic CO2 conversion of the Institute of chemistry just showed two points: one was the loopholes in the planning at the initial stage of project preparation, and the other was the delay of the work of relevant departments. The losses in the past two years have been caused. I just hope that the relevant departments will seize the time, improve work efficiency, run the project as soon as possible, and give full play to its due social energy efficiency
