With the continuous growth of global demand for clean energy, the new energy industry is booming. The scale of development and utilization of new energy sources such as solar energy, wind energy, and hydropower is continuously expanding. Against this backdrop, new energy substations, as the key hub between new energy power generation systems and the power grid, are becoming increasingly important. They not only undertake the functions of transforming, distributing, and controlling new energy electricity, but also play a decisive role in ensuring the efficient, stable, and safe connection of new energy electricity to the power grid. In-depth understanding of the application of new energy substations in the new energy industry is of great significance for promoting the sustainable development of the new energy industry.

In the power industry, power transformers are the core "hubs". On the generation side, they step up the low voltage output by generators to ultra - high voltage, reducing long - distance power transmission losses and ensuring efficient power transmission. At the consumer end, they accurately step down the high voltage to standard voltages suitable for residential, commercial, and industrial use. In substations, transformers distribute electrical energy rationally to various areas, meeting diverse power demands. When there are system failures or voltage fluctuations, they can stabilize the voltage and isolate faults relying on their own characteristics, ensuring the continuous, safe, and reliable operation of the power system, and providing a solid power guarantee for social production and daily life.

In the construction industry, power transformers are key devices for ensuring a stable power supply in buildings. Buildings such as large commercial complexes, office buildings, and high - rise residential buildings have complex and huge power demands. Power transformers can convert the high - voltage electricity input from the urban power grid into safe and suitable low - voltage electricity to meet the power needs of lighting, air - conditioning, elevators, and various office and household appliances within the building. For example, in an office building, when numerous office appliances are operating simultaneously, the transformer accurately regulates the voltage to ensure a stable power supply. During the construction phase, it also provides reliable power for construction equipment, ensuring the smooth progress of construction projects and comprehensively safeguarding the power requirements in the construction field.

In a data center, power transformers serve as the cornerstone of stable energy supply. Equipment in data centers operates continuously around the clock, demanding extremely high power stability. Power transformers convert high - voltage utility power into voltages suitable for data center equipment, powering servers, storage devices, cooling systems, and more. For instance, when large - scale server clusters are in operation, the power consumption is enormous. Transformers precisely regulate the voltage to ensure a smooth power delivery and prevent voltage fluctuations from damaging the equipment. Moreover, in the face of potential power consumption peaks and unexpected situations in the data center, transformers, with their high - efficiency voltage - transformation capabilities, continuously provide reliable power, guaranteeing the efficient, safe, and stable operation of the data center and supporting the storage and processing of massive amounts of data.

In the field of industrial and mining enterprises, power transformers play an irreplaceable and crucial role. Industrial and mining enterprises have numerous devices with large and complex power loads. Power transformers accurately convert the electrical energy input from the high - voltage power grid into voltage levels suitable for various production equipment. For example, the large - scale smelting equipment in steel plants and the mining machinery in mines consume an astonishing amount of electricity during operation. Transformers, with their excellent voltage - regulating capabilities, ensure stable power supply, preventing voltage instability from affecting production efficiency and damaging equipment. At the same time, transformers help enterprises allocate electrical energy rationally, reducing energy consumption costs, providing a solid power guarantee for the efficient and safe production of industrial and mining enterprises, and promoting the orderly operation of industrial production.

Outdoor prefabricated substations are widely used in various scenarios. In urban construction, they can quickly supply power to new residential areas and commercial centers. Their compact design saves space and they are easy to install, thus promptly meeting power demands. At temporary construction sites, such as road construction and building construction areas, they can be flexibly deployed to stably power construction equipment and ensure project progress. In remote areas like mountainous regions and oil fields, their ability to adapt to harsh environments comes into full play, continuously providing power for local production and daily life. Thanks to their integration advantages, prefabricated substations efficiently contribute to power supply in various fields and are an indispensable part of the modern power system.
