6 FAQs about [The working principle of photovoltaic support rail]
Can photovoltaic power be used in rail transit?
As a secondary energy, electric power is clean, but the power of rail transit mainly comes from urban power grid. That is to say, most of the power used in rail transit is traditional thermal power. In order to realize the low-carbon transformation of energy, this paper introduces photovoltaic power generation into rail transit power supply system.
Can photovoltaic power power a railway?
However, the development of electrified railways is limited in the weak areas of China’s power grid. To surpass these limitations, we turn our attention to new railway energy sources, among which the most suitable is photovoltaic power generation.
Should solar PV be introduced into the railway energy supply system?
Solar PV generation is concentrated in the daytime period, matching the railway load, so it is appropriate to introduce solar PV generation into the railway’s energy supply system (IEA,2019). Therefore, a series of railway system transformations are needed to fully exploit this advantage.
Can photovoltaic power generation & rail transit power supply system work in China?
From this, we can know that in any region of China, the grid connection of photovoltaic power generation and rail transit power supply system is feasible. Even more, it has great development space. Literature , respectively take Shenzhen Metro Line 6 and Guangzhou Metro Yuzhu depot as examples.
Who needs a PV project connected to the railway traction network?
However, not only the direct feed into the traction current network will be considered, but also internal consumers in the railway sector that are close to the generation point. In the third phase of the project, the TÜV Rheinland experts will establish the main requirement for PV projects connected to the railway traction network.
How BS-HSR's electricity demand was covered by the railway PV system?
The PV system provided power to the railway system from 5 a.m. to 7 p.m. The railway PV systems were able to cover BS-HSR's electricity demand before 6 p.m. The local railway PV generation satisfied 93.4% of the electricity demand in Jiangsu without the assistance of energy storage devices.
