BMP Prefabricated cabin substation

Overview

The main function of the prefabricated cabin substation is to convert the low-voltage alternating current produced by generation systems in the renewable-energy sector into medium-voltage alternating current and to feed this energy into the grid.

The prefabricated cabin substation integrates the low-voltage cabinet, transformer, ring main unit, auxiliary power supply and other equipment in a steel-structure container, providing a highly integrated transformer and distribution solution for the medium-voltage grid connection of ground-mounted power stations.

Features

• Smart:
• 1. Real-time monitoring of the operating status of the LV cabinet, transformer and ring main unit
• 2. Online measurement of electrical parameters, with current and voltage measurement accuracy up to class 0.5
• 3. Remote control of the main circuit breakers of the LV cabinet and ring main unit, and remote retrieval of the substation's operating data
• Simple:
• 1. All internal equipment is prefabricated and installed in the factory
• 2. Compact 20 ft container structure, suitable for a wide range of transport conditions and easy to install
• Reliable:
• 1. Robust and reliable structural design
• 2. IP54 degree of protection for both the LV and MV compartments
• Rapid deployment:
• 1. Enables rapid deployment on site
• 2. Only the LV incoming and MV outgoing cable connections need to be made on site

Applications

• Ground-mounted PV plants
• Wind farms
• Renewable-energy grid connection
• Sites requiring rapid deployment
