III. Advantages of Data Center Diesel Generators
Data center diesel generators, as core equipment for ensuring business continuity, have advantages in reliability, cost-effectiveness, adaptability, and intelligent management, making them especially suitable for data center scenarios with very high power supply requirements.
1. Reliable, Independent Power Supply
Independent of the grid: In the event of natural disasters or grid failures that completely disable utility power, data center diesel generators can operate independently to provide continuous power to the data center.
Rapid response: Starts and stabilizes power supply within 10-15 seconds, seamlessly connecting with the UPS to prevent business interruptions.
2. Cost-effective and Efficient
Low fuel cost: Diesel has a high thermal efficiency and is usually cheaper than gasoline, making long-term operation more economical.
Easy maintenance: Durable structure, low wear rate of components, long lifespan, and low total lifecycle cost.
3. Strong Adaptability
Wide power coverage: Meets the needs of small to large-scale data centers.
Suitable for extreme environments: Can operate reliably in conditions from -40°C to 50°C, at high altitudes, and in moisture- and dust-prone environments.
4. Intelligent Management
Remote monitoring: Real-time monitoring of voltage, frequency, and other parameters of the data center diesel generator, with automatic alerts for anomalies, and support for remote fault diagnosis.
Automatic start and stop: Automatically switches based on utility power status and load demand, reducing manual intervention.
5. Environmentally Friendly and Compliant
Low emissions: Equipped with exhaust treatment devices to meet relevant environmental standards and reduce pollution.
Energy-saving design: Supports an economical operating mode, with some models capable of waste heat recovery to improve energy efficiency.
IV. Precautions for the use of data center diesel generator in low temperature weather in data centers
1. Fuel management: anti-freezing and anti-blockage
Change to winter diesel: Choose low-grade diesel (such as -10, -20) according to the local minimum temperature to avoid ordinary diesel blocking the oil circuit due to low temperature wax evolution.
Keep the fuel tank clean: Regularly drain the water at the bottom of the tank to prevent freezing and expansion; Replace the high-precision fuel filter to avoid clogging of impurities.
2. The data center diesel generator starts to warm up
Fully preheat the data center diesel generator in the data center: Before starting, turn on the preheating device (such as the preheating plug) provided by the diesel generator in the data center, and start it after the indicator light goes off to avoid damage to the machine from cold start.
Avoid frequent starting: If the first start fails, try again at intervals of 1-2 minutes, and check whether the oil circuit and circuit are normal.
3. Lubrication and maintenance of data center diesel generator
Replace low-temperature oil: The viscosity of the oil increases at low temperature, so it is necessary to replace it with oil with good low-temperature performance (such as 5W-30) to ensure sufficient lubrication during start-up.
Check the oil level: Check the oil level regularly to ensure that it is between the upper and lower limits of the ruler to avoid increased oil consumption due to low temperatures.
4. Cooling system
Use antifreeze: If antifreeze is not used, wait for the water temperature to drop below 60°C after shutdown, drain the cooling water, and prevent freeze cracking of the water tank or engine.
Check tightness: Regularly check whether the interfaces and water pipes of the diesel generator cooling system in the data center are leaking, and replace the aging pipelines in time.
5. Power guarantee for data center diesel generator
Keep the battery fully powered: Low temperatures will reduce the battery capacity, so check the battery regularly to ensure that the quiescent voltage is not less than 12.4V.
Add a thermal insulation jacket: Install a thermal insulation jacket around the battery or use a heater to prevent the battery temperature from degrading due to too low temperature.
6. Operation contraindications
Do not bake with open flame: Do not use open flame to heat the oil pan or intake pipe to prevent oil deterioration or fire.
No waterless starting: It is strictly forbidden to start the data center diesel generator first and then add cooling water to avoid cracks caused by sudden changes in cold and heat.
7. Emergency preparation for data center diesel generator
Reserve key spare parts: Stock up on fuel filters, oil filters, preheat plugs, batteries and other wearing parts in advance.
Formulate emergency plans: Formulate emergency procedures for scenarios such as startup failure and fuel solidification, and clarify the operating steps and responsible persons.
V. Q&A About Data Center Diesel Generators
1. What is "N+1 redundancy" for data center diesel generators?
This is the baseline for high availability. For example, if your data center requires 3 generators to handle the full load, you install 4. This way, even if one fails or is under maintenance, the remaining 3 can fully cover the load, and business operations are not affected.
2. Why do data centers equip diesel generators?
Diesel generators provide power backup for data centers, capable of starting within 10 seconds and running at full load in case of a power outage, ensuring continuous operation. Their main advantages are: strong instantaneous load capacity, high reliability in extreme environments, and outstanding cost-effectiveness.
3. How do data center diesel generators generate electricity?
The diesel engine converts chemical energy into mechanical energy: air mixes with atomized diesel, and the mixture is compressed and ignited by the piston, causing combustion and expansion. This drives the piston to do work, rotating the crankshaft. The crankshaft is coaxially connected to the generator rotor, which generates electricity through electromagnetic induction.
VI. Application Scenarios of Data Center Diesel Generators
1. Core Assurance: Power backup during utility outages
When the utility power is completely cut off, the UPS can only last for a few minutes. At this time, the data center diesel generator will automatically start within 10-15 seconds and seamlessly take over all critical loads through the ATS system, providing continuous power for servers and cooling systems to ensure zero business interruption.
2. Strategic Support: Enhancing system resilience and maintainability
Confidence for planned maintenance: During maintenance of the main power equipment, it is possible to actively switch to the data center diesel generator to achieve "uninterrupted" maintenance.
Key for health checks: Regular load tests are the only way to verify the reliability of the backup system.
3. Value Extension: From cost center to revenue source
Participating in grid peak shaving, supplying power to the grid during peak demand periods.
As a demand-side response resource, generating additional revenue for the data center.
When the mains power is interrupted, the data center diesel generator automatically starts and takes over all critical loads through the ATS system, ensuring the continuous operation of servers and cooling systems, thereby maintaining business continuity. Users should choose a suitable data center diesel generator based on their specific operational needs.
