Solar Compact Prefabricated Substation Product Description
The compact substation (also known as box substation or prefabricated substation) is a high-integration compact power equipment that integrates high-voltage switchgear, transformer and low-voltage power distribution device, and the Solar Compact Prefabricated Substation is a specialized variant of this equipment, tailor-made for new energy power generation scenarios represented by photovoltaic power generation. All components of the Solar Compact Prefabricated Substation are integrated in a metal or non-metal sealed box to form a complete and independent power distribution system, whose core function is to convert the high-voltage electric energy of the power grid into low-voltage electric energy matching user demand, and realize efficient distribution, precise control and safe transmission of electric energy, and it is also the core power conversion equipment for the Solar Prefabricated Station to connect to the public power grid.
As a core supplier in the domestic wind power generation and solar photovoltaic power generation step-up equipment market, Vziman Electric is based on the mature design and manufacturing technology of pad-mounted transformers and conventional prefabricated substations, and fully combines the operational characteristics of wind turbines, solar photovoltaic inverters, as well as the technical requirements of relevant power transmission and distribution networks for step-up equipment. We have independently developed a new generation of high-efficiency compact substations for new energy power generation, among which the Solar Compact Prefabricated Substation is optimized for the power generation characteristics of the Solar Prefabricated Station, perfectly matching the step-up, grid connection and power distribution needs of photovoltaic power generation projects, and becoming a key supporting equipment for the efficient operation of solar new energy power generation systems.
Solar Prefabricated Station Core Product Features
- High Integration Design, Adapted to Solar Power Station Layout:The Solar Compact Prefabricated Substation inherits the compact structural advantage of conventional compact substations, with all power conversion and distribution components integrated in a sealed box, featuring small footprint and light weight. This design is highly suitable for the decentralized layout characteristics of the Solar Prefabricated Station, which can be flexibly installed in photovoltaic panel clusters, avoiding occupying a large area of photovoltaic power generation land, and realizing integrated deployment with the power generation system.
- High Efficiency Power Conversion, Reducing Solar Power Station Loss:Optimized for the DC-AC conversion power characteristics of photovoltaic power generation, the Solar Compact Prefabricated Substation is equipped with a high-efficiency energy-saving transformer, with ultra-low no-load loss and load loss, which can maximize the conversion and utilization of electric energy generated by the Solar Prefabricated Station, effectively reducing the power loss in the step-up and distribution process, and improving the overall power generation efficiency of the photovoltaic project.
- Specialized Grid-Connection Design, Matching Solar Power Station Demand:The Solar Compact Prefabricated Substation has a customized grid-connection circuit design, which is perfectly compatible with the output parameters of solar photovoltaic inverters, and can realize smooth grid connection between the Solar Prefabricated Station and the municipal power grid/industrial power grid. It is equipped with a dedicated anti-islanding protection module, which meets the national new energy grid-connection standards and ensures the safety and stability of the photovoltaic power generation system and the public power grid during parallel operation.
- Sealed Protective Structure, Adapting to Solar Power Station Outdoor Environment:Adopting a fully sealed and weatherproof structural design, the Solar Compact Prefabricated Substation has excellent resistance to high temperature, ultraviolet radiation, dust and rain, which can adapt to the long-term outdoor operation environment of the Solar Prefabricated Station (mostly built in open areas such as roof, desert and plain). Its shell is treated with special anti-corrosion and anti-UV coating, effectively extending the service life of the equipment in harsh outdoor conditions.
- Intelligent Monitoring, Realizing Solar Power Station Unattended Operation:The Solar Compact Prefabricated Substation is equipped with an intelligent online monitoring system, which can real-time collect and transmit the equipment's operating parameters such as voltage, current, temperature and load. It supports remote data viewing and fault alarm, which is perfectly matched with the unattended operation mode of the large-scale Solar Prefabricated Station, reducing the on-site operation and maintenance workload and improving the management efficiency of the power generation project.
