The power supply system for urban rail transit consists of the entire power supply system that delivers electricity to the trains running on the urban rapid transit line through high-voltage transmission networks, step-down at main substations, distribution networks, and step-down and rectification

Hydropower, also known as hydroelectric power, utilizes the potential energy of water located at higher elevations (such as rivers and lakes) flowing to lower elevations. This energy is converted into kinetic energy by water turbines, which then drive generators to produce electricity. In a sense, h

Photovoltaic energy, also known as solar photovoltaic power generation, is the process of converting solar energy into electrical energy based on the photovoltaic effect.Compared with traditional fossil energy and nuclear power generation, photovoltaic power generation has many advantages. First, it

Wind Energy refers to the use of wind to generate electricity. It is a clean and renewable energy source. Wind power generation is environmentally friendly, as it harnesses the kinetic energy of wind to produce electricity. Unlike fossil fuel-based methods, wind power does not require fuel and has n

Nuclear power generation utilizes the heat energy released from nuclear fission in reactors to generate electricity. It is an important method for achieving low-carbon power generation. Unlike fossil fuel-based electricity generation, nuclear power does not emit significant amounts of pollutants int
