Application of Photovoltaic Prefabricated Substation
As a modular and integrated power facility, photovoltaic prefabricated cabin substations have been widely applied in various fields such as new energy power generation, grid regulation, data centers, and overseas power projects. They possess significant advantages such as short construction periods, small footprint, strong environmental adaptability, and the capability for mobile deployment.
Main application scenarios
- Photovoltaic power generation system
In both centralized and distributed photovoltaic power stations, photovoltaic prefabricated cabinets are utilized to integrate key equipment such as step-up transformers, inverters, and grid-tie cabinets. Their high protection level (above IP54) and weather-resistant design effectively withstand harsh environments like dust, high temperatures, and low temperatures, ensuring long-term stable operation of the equipment. For instance, large-scale photovoltaic power stations in the northwest region utilize 35kV prefabricated cabinet step-up stations, achieving three years of trouble-free operation.
- energy storage power station
Prefabricated cabin is the mainstream carrier of electrochemical energy storage system, integrating lithium battery pack, PCS, BMS, fire protection and temperature control system to form a standardized "energy storage unit". For example, the 220 kV energy storage power station in Shanxi Ruan'an is composed of 80 prefabricated cabins, with a single cabin capacity of 5MWh, achieving fast charging and discharging and stabilizing grid fluctuations.
- wind farm supporting facilities
Onshore and offshore wind power projects utilize prefabricated cabinets to construct step-up stations or pitch control centers. In offshore applications, IP66 protection and dual anti-corrosion treatment are adopted, providing salt spray resistance for over 10 years and significantly enhancing equipment reliability.
- AI computing power and data center power supply
Facing the high-density computing power demand, enterprises adopt prefabricated cabin-style substations in the form of "power modules" to provide reliable power supply for data centers. Mingyang Electric customizes such products for customers like ByteDance and Heying Data, solving the problem of "difficulty in power transmission", with a gross profit margin of around 25%.
- New energy vehicle charging and swapping facilities
Rapidly deployable battery swapping stations commonly adopt prefabricated cabin structures, integrating battery swapping robots, charging modules, and battery storage racks. They can be installed within two weeks, significantly enhancing construction efficiency.
- Overseas market expansion
Chinese manufacturers are accelerating the export of prefabricated module technology and standards. The world's first 400 kV prefabricated module substation manufactured by TGOOD has been exported to Oman, reducing the construction period by 60%, saving costs by 10%, and reducing land occupation by 50% compared to traditional civil engineering solutions.
Technological development trend
Currently, prefabricated cabin technology is evolving towards higher voltage levels (such as 400kV), intelligent operation and maintenance (digital twins, remote monitoring), and environmentally friendly materials (non-metallic composite cabin bodies). At the same time, it continues to expand its application boundaries in emerging scenarios such as hydrogen compressor rooms and power supply and distribution in semiconductor factories.
