Application of Diesel Generator Sets in the Telecommunication

Application of Diesel Generator Sets in the Telecommunication

I. Industry Background and Requirements

As critical national infrastructure, the telecommunications industry demands uninterrupted and stable power supply. Facilities such as data centers, 5G base stations, and transmission nodes may cause large-scale communication failures if power is interrupted, leading to significant economic and social impacts. Diesel generator sets have become the core backup power solution for the telecom industry due to their rapid response, high reliability, and long-duration power supply.

II. Typical Application Scenarios

Data Centers

Requirements: Tier III/IV data centers require 99.982%+ availability.

Solution:

N+1 redundancy configuration (e.g., 2×2000kW units supporting 1500kW load).

0-second transfer ATS system, working with UPS to form a "grid-UPS-generator" three-level protection.

Silent containerized units (noise ≤75dB@1m).

5G Base Stations

Features:

Distributed deployment, with 60% of stations located in areas with weak grid infrastructure.

Single-station power consumption: 3-5kW (AAU equipment requires 24/7 power).

Solution:

Compact silent units (10-50kW) with intelligent fuel-saving mode.

Remote start/stop control, supporting IoT platform for power monitoring.

Core Equipment Rooms/Transmission Nodes

Standard: Compliant with YD/T 502-2007 Technical Requirements for Diesel Generator Sets in Telecommunications.

Configuration:

High-voltage units (10kV) for provincial core equipment rooms.

Dust-proof units (IP55) for remote mountainous sites.

III. Special Technical Requirements for Telecom Applications

Special Functional Requirements:

Harmonic Suppression: THD <3% (to avoid interference with telecom equipment).

Smart Start/Stop: Supports grid quality analysis (early triggering for voltage dips/frequency fluctuations).

Fuel Management: Dual-tank system (primary + backup) with auto-switching.

IV. Technology Evolution Trends

Greener Solutions

Biodiesel (B20) adoption to reduce carbon emissions.

Hybrid energy systems (solar + storage + diesel) to lower operating costs.

Intelligent Features

AI-based predictive maintenance (oil analysis, vibration monitoring).

Digital twin technology for load surge simulation.

Modular Design

Prefabricated power containers (integrated generation, distribution, cooling).

Plug-and-play maintenance (15-minute replacement for critical components).

V. Case Studies

China Mobile Hohhot Data Center: 32× Caterpillar 3516B units (1800kW each) for Tier IV power assurance.

Huawei Southeast Asia 5G Base Stations: 500+ Deca Power silent units (20kW) adapted for tropical climates.

VI. Selection Guidelines

Telecom users should prioritize:

Industry Certifications: TLC/YD/T 502 compliance.

Smart Management: Deep integration with power monitoring systems.

Local Service: On-site maintenance response within 2 hours.

*(Note: Mountain base stations require lightning protection ≥40kA, while island sites need salt spray corrosion-resistant models.)*

Through professional customization, diesel generator sets can fully meet the telecom industry's demands for zero downtime, high intelligence, and low TCO in power assurance.
