Nanjing Oulu Electric's Self-Developed Monitoring & Management System for Telecom Base Stations

Energy Conversion & Storage

• Hybrid Wind-Solar Charging: Converts wind (AC→DC) and solar energy into stable DC 53.2V for battery charging.

Battery Management

• Smart Charging Control: Implements equalization/float charging via real-time voltage/current sampling.

• Comprehensive Protection:

• Overvoltage/undervoltage cutoff

• Overcharge/over-discharge prevention

• Overload protection for batteries and loads

Data Monitoring & Analysis

• System Logging: Records parameter trends and alarms for predictive maintenance.

• Energy Statistics: Tracks daily/monthly/annual power generation (wind/PV) and consumption.

• Remote Telemetry (RS485, 9600bps): Monitors:

• Battery current/temperature/SOC

• Array output (voltage/current)

• Load status

Safety & Reliability

• Surge Protection: Integrated lightning arresters for PV/wind modules.

• Load Prioritization: Configurable two-stage load shedding (primary/secondary) to prevent battery over-discharge.

• Fail-Safe Alerts:

• Fault signals for fuses/breakers

• Backup power activation trigger (grid/diesel generator)

Modular Design

• Hot-Swappable Components: Facilitates maintenance and capacity expansion.

• YD/T1363.3 Compliance: Ensures interoperability with telecom industry equipment.
