Question 1

What are the advantages of containerized generators?

Accepted Answer

Plug-and-play deployment (no civil works). IP55 protection vs IP23 canopy. Integrated 24-72hr fuel tank. Remote monitoring standard. Transportable by truck, ship, or helicopter. Operates -40degC to +55degC. Ideal for mining, islands, disaster relief, and rental fleets.

Question 2

What sizes are available for containerized generators?

Accepted Answer

20ft ISO container: 500-1000kW. 40ft ISO container: 1000-3000kW. All CSC-certified for ocean freight and stackable. Dual-frequency (50/60Hz) optional. Standard lead time: 30-50 working days.

Question 3

What certifications does the containerized generator have?

Accepted Answer

ISO 8528, ISO 3046, IEC 60034, CE, SONCAP. EPA Tier 2/3 and EU Stage IIIA compliant. Container: CSC-certified, IP55 rated. All units factory load-tested before shipment.

Question 4

How to convert kW to kVA for a diesel generator?

Accepted Answer

Active Power (kW) = actual work output. Apparent Power (kVA) = total system capacity. Formula: kVA = kW / Power Factor. Example: 90kW / 0.9 PF = 100kVA. Diesel generators typically run at PF 0.8-0.9.

Question 5

What are the parallel operation conditions for diesel generator sets?

Accepted Answer

Parallel operation requires matching voltage, frequency, and phase sequence between units. Use a dedicated automatic parallel controller. Never attempt manual parallel without proper training. Benefits: load sharing, fuel efficiency, redundancy.

Question 6

What does the power rating of a diesel generator mean?

Accepted Answer

Prime Power: continuous variable load operation. Standby Power: emergency use only, max 200h/year. Continuous Power: constant load, always-on applications. Never exceed rated power to avoid overheating and缩短寿命.

Question 7

How much fuel does a diesel generator consume?

Accepted Answer

Fuel consumption = rated power x specific fuel consumption x load factor. Example: 500kW at 75% load uses approx. 0.19 L/kWh = 71.25 L/h. Run at 70-80% load for optimal efficiency. Under-loading (<30%) causes carbon buildup.

Question 8

Why is regular maintenance critical for diesel generators?

Accepted Answer

Every 500h: change engine oil and filters. Every 250h: check air filters, fuel filters, coolant, battery. Every 1000h: inspect belts, hoses, turbocharger. Annual: full engine inspection. Proper maintenance ensures快速启动 and可靠运行.

Question 9

What is power factor and why does it matter?

Accepted Answer

Power factor (PF) = real power (kW) / apparent power (kVA). Most diesel generators are rated at PF 0.8. Loads with low PF (motors, AC) require larger generators. Always size generator: kVA = kW / 0.8.

Question 10

Why run diesel generators in parallel?

Accepted Answer

Parallel operation provides: (1) N+X redundancy for critical loads, (2) load sharing to optimize fuel efficiency, (3) scalability - add units as demand grows, (4) maintenance without downtime. Essential for hospitals, data centers, and telecom infrastructure.
