Photovoltaic prefabricated substation: a pioneer in promoting efficient transmission of green energy
Publish Time: 2024-08-05
In the context of today's global energy transformation, solar energy, as a clean and renewable energy source, is increasingly becoming an important choice for optimizing the energy structure of countries around the world. The rapid development of photovoltaic power generation technology has not only promoted the greening of energy production, but also put forward higher requirements for power transmission and distribution systems. Photovoltaic prefabricated substations, as an indispensable part of photovoltaic power generation systems, play a vital role in the efficient transmission of green energy with their unique integrated design and high-efficiency performance.
Overview of photovoltaic prefabricated substations
Photovoltaic prefabricated substations, also known as European box transformers or Chinese transformers, are highly integrated power equipment. It cleverly integrates step-up transformers, high-voltage switchgear, low-voltage switchgear and necessary auxiliary equipment to form a compact and fully functional power conversion and distribution unit. This design not only greatly reduces the workload of on-site installation and shortens the construction period, but also improves the overall operating efficiency and reliability of the equipment.
Core technical features
Oil-immersed transformer: The core component of the photovoltaic prefabricated substation is the oil-immersed transformer, which is responsible for boosting the low voltage (such as 0.315kV, 0.36kV, 0.52kV, 0.63kV, 0.8kV, etc.) emitted by the photovoltaic power generation components to 10kV to meet the access requirements of the power grid. The oil-immersed transformer ensures the high efficiency and safety of power conversion with its good heat dissipation performance and high insulation strength.
Outdoor radiator: In order to further optimize the heat dissipation effect, the radiator of the photovoltaic prefabricated substation is usually designed outdoors. This design not only improves the operating stability of the transformer, but also extends the service life of the equipment. At the same time, it is also convenient for daily maintenance and overhaul.
Highly integrated: By integrating a variety of power equipment into a box, the photovoltaic prefabricated substation has achieved the advantages of small footprint, light weight, and flexible mobility. This not only saves land resources, but also facilitates rapid deployment in complex terrain or remote areas.
Intelligent control: Modern photovoltaic prefabricated substations are also equipped with advanced intelligent control systems, which can monitor the operating status of the equipment in real time, detect and handle faults in time, and improve the automation level and operating efficiency of the system.
Application value and prospects
As an important supporting equipment for photovoltaic power generation systems, the application value of photovoltaic prefabricated substations is self-evident. It can not only effectively connect decentralized photovoltaic power generation units to form a large-scale grid-connected power generation system, but also transmit low-voltage electricity to more distant areas through boost conversion to meet a wider range of electricity needs.
With the continuous growth of global demand for renewable energy and the continuous advancement of photovoltaic technology, the market prospects of photovoltaic prefabricated substations are very broad. In the future, with the construction and development of new power systems such as smart grids and microgrids, photovoltaic prefabricated substations will pay more attention to the development trend of intelligence, modularization and standardization to better adapt to the application needs in different scenarios.
In short, as an important carrier of green energy transmission, photovoltaic prefabricated substations are contributing important forces to promote global energy transformation and sustainable development with their unique technical advantages and extensive application value.
