With the widespread adoption of communication equipment, there are increasingly high demands for signal coverage. To achieve coverage across vast grasslands and mountainous areas, numerous base stations must be established, most of which are located in regions not covered by the national power grid. Therefore, wind-solar hybrid power supply systems have become one of the solutions for powering communication base stations in remote areas.

Nanjing Oulu Electric's independently developed and manufactured wind-solar hybrid power generation system for communication base stations adopts modular control. The system is divided into grid power modules, photovoltaic modules, wind turbine modules, and diesel generator modules. Each module operates independently while coordinating with others, facilitating maintenance and expansion. The system complies with base station power supply standards.

The photovoltaic control module features high-voltage input and MPPT control, achieving an energy conversion efficiency of up to 92%. All system modules adopt plug-and-play installation, simplifying later maintenance and upgrades. The system provides stable and reliable power supply, enabling unattended operation, remote monitoring, and minimal daily maintenance.

Nanjing Oulu Electric's wind-solar hybrid power supply system for communication base stations consists of the FD series wind turbines, solar panels, centralized communication power management system, battery bank, and outdoor battery insulation enclosure.

The centralized communication power management system adopts a modular design, fully meeting communication power standards. It supports hot-swapping and hot-backup for photovoltaic control modules, wind turbine control modules, and rectifier modules. It includes a hybrid power monitoring module and provides communication interfaces that meet industry requirements.

The wind-solar hybrid power supply system for communication base stations not only has comparable or slightly lower investment costs compared to grid power connection, effectively solving the difficulty of grid power access, but also significantly reduces annual electricity expenses and decreases carbon dioxide emissions. This achieves the goal of energy conservation and consumption reduction, contributing to the development of a low-carbon society.
