Cummins 800kW Diesel Generator Set (KTA38-G5 + Leroy-Somer) Technical Analysis
In the field of large-scale standby and prime power supply, the reliability, power performance and stability of generator sets directly determine the continuity of production and operation. The Cummins 800kW diesel generator set, equipped with the Chongqing Cummins KTA38-G5 engine and Leroy-Somer 800kW generator, forms a high-end power supply solution with strong power, optimized energy consumption and convenient operation and maintenance through the in-depth adaptation of core technologies of both parties. It is widely used in industrial plants, data centers, commercial complexes, large-scale infrastructure and other scenarios with strict requirements on power supply quality.
I. Core Power Unit: Cummins KTA38-G5 Engine
As the “heart” of the unit, the Cummins KTA38-G5 engine is a high-power model built by Chongqing Cummins in accordance with global unified design standards. After years of technical iteration and working condition verification, it has achieved a precise balance between reliability and economy. Adopting a 12-cylinder V-type structure with a displacement of 37.8L, the engine combines turbocharging and intercooling technology, which can stably output power under complex working conditions and easily support the 800kW continuous power demand.
In terms of structural design, the KTA38-G5 has multiple core advantages: the cylinder block is made of high-strength alloy cast iron, combined with cross bolts to fix the main bearing cap, featuring extremely high rigidity, which effectively reduces operating vibration and noise; the four-valve design per cylinder optimizes the air-fuel ratio, and the single camshaft accurately controls valve and injection timing, improving combustion efficiency while reducing emissions; the integral forged steel crankshaft is induction hardened to significantly enhance fatigue strength, and matched with aluminum alloy ω-type pistons, which can adapt to thermal expansion and contraction and ensure long-term operation tightness and stability.
The fuel system adopts Cummins’ unique PT pump direct injection technology, with wear compensation function and dual flyweight governor. The injection pressure is stably above 120MPa to achieve precise fuel control. Cooperated with a large-capacity intercooler, it makes the intake air denser and further optimizes fuel consumption. The cooling system uses a gear-driven centrifugal water pump, and the large-volume water channel design ensures uniform heat dissipation of key components such as cylinder liners and valves. Equipped with a spin-on anti-corrosion filter, it effectively inhibits rust and impurity accumulation and extends the service life of the unit.
II. High-Efficiency Power Generation Unit: Leroy-Somer 800kW Generator
As a world-renowned generator manufacturer, Leroy-Somer is famous for its high efficiency, low loss and strong anti-interference ability. Its compatibility with the Cummins KTA38-G5 engine has passed strict tests to ensure efficient conversion of power into electrical energy. This 800kW generator adopts a brushless rotating magnetic field structure, combined with a self-excited automatic voltage regulation excitation system, which has high voltage regulation accuracy, can quickly respond to load fluctuations and ensure power supply stability.
The generator is designed with H-class insulation, featuring excellent high-temperature resistance and long-term safe operation in harsh environments. With an IP23 protection level, it can effectively resist dust and slight water stains. The winding adopts a 2/3 pitch structure, and combined with precise electromagnetic design, the Telephone Interference Factor (TIF) is less than 50, the Telephone Harmonic Factor (THF) is less than 2%, and the radio interference meets the G and N class standards of BS800 and VDE, which can meet the power supply needs of precision equipment with high requirements on electromagnetic compatibility.
In addition, the generator adopts a single-bearing design, with a compact structure, which is convenient for coaxial connection with the engine, achieving higher transmission efficiency and reducing operating noise and vibration. The three-phase four-wire Y-type connection is suitable for mainstream power supply needs, with a stable power factor of 0.8 lagging, which can give full play to power generation efficiency and avoid energy waste.
III. Overall Unit Performance and Core Advantages
The combination of the Cummins KTA38-G5 engine and Leroy-Somer 800kW generator not only complements each other in core components, but also maximizes performance in system integration. The unit complies with ISO8528-2005 and GB/T2820-2009 standards, and the manufacturing process has passed ISO9001 quality system certification, providing comprehensive quality assurance.
In terms of operating performance, the unit has a continuous power of 800kW and a standby power of up to 880kW, with a stable speed of 1500r/min and a precisely controlled frequency of 50Hz. The fuel consumption rate is as low as 208g/kw·h, which is far superior to competitors of the same power level, and can significantly reduce fuel costs during long-term operation. The voltage steady-state regulation rate is ≤±1%, the frequency stabilization time is ≤3 seconds, and the voltage waveform distortion rate is ≤8%, which can provide high-quality electrical energy for precision instruments and industrial production lines.
In terms of operational convenience, the engine adopts a per-cylinder head design, which can be disassembled individually during maintenance, reducing downtime; the unit is equipped with an LCD digital display controller, which real-time monitors key parameters such as speed, oil temperature, water temperature, voltage and current, and has fault alarm and automatic protection functions. Cummins’ global service network provides 24-hour technical support, and the whole unit enjoys a 1-year or 1000 operating hours quality guarantee, covering the engine, generator and control system, completely solving users’ worries.
