A 300kW diesel generator is a robust power generation system widely used for industrial, commercial, and emergency backup applications. Below is a structured overview of its key features, technical specifications, and applications, based on industry standards and market data.
1. Core Components
- Engine: Typically a 4-stroke, turbocharged, intercooled diesel engine (e.g., Cummins, Yuchai, or Weichai) designed for high efficiency and durability
- Alternator: Brushless AC generator with automatic voltage regulation (AVR), ensuring stable output (e.g., Stamford, Marathon, or domestic brands like Suzhou Defeng)
- Control System: Equipped with intelligent controllers (e.g., HGM6010 or HGM6110U) for automatic start/stop, fault monitoring, and synchronization
- Cooling System: Closed-loop water cooling to maintain optimal operating temperatures, even in high ambient conditions (up to 40°C)
2. Key Technical Specifications
| Parameter | Value/Description |
|---|---|
| Rated Power | 300kW (standby: 330kW) |
| Voltage/Frequency | 400V/230V, 50Hz |
| Power Factor | 0.8 (lagging) |
| Fuel Consumption | ~205–226 g/kWh (full load) |
| Steady-State Regulation | Voltage: ≤±0.5%; Frequency: ≤±2% |
| Dimensions/Weight | ~3200×1270×1950 mm / 3200 kg (varies by model) |
3. Applications
- Industrial: Mining operations, construction sites, and manufacturing plants requiring reliable power in remote areas
- Emergency Backup: Hospitals, data centers, and urban infrastructure during grid outages
- Specialized Uses:
- Silent Models: Noise-reduced versions (e.g., <75 dB) for urban environments
- Mobile Units: Trailers or containerized systems for temporary power supply
4. Market Insights
- Price Range: ~13,000–18,000 (varies by brand and configuration; Yuchai models start at ~$15,000)
- Industry Trends: Over 4,000 manufacturers in China, with top 35 companies holding ~50% market share. Competitive focus includes energy efficiency and smart control integration
5. Operational Considerations
- Altitude Adaptation: Requires derating above 1,000 meters
- Maintenance: Simplified due to lack of spark plugs/carburetors; routine checks on oil, coolant, and filters
- Compliance: Meets non-road emission standards (e.g., China Stage II)
