500KW Chongqing Cummins Generator Set KTAA19-G6A

The KTAA19-G6A engine of the 500KW Chongqing Cummins generator set adopts Cummins patented PT fuel system, which not only meets environmental emissions but also has higher reliability, durability, power and fuel economy. The specific parameters are as follows:

Main technical indicators of diesel generator set:

1. Unit output power: standby: 550KW (commonly used: 500KW)

2. Voltage:

1) Rated voltage: 400/230V three-phase four wire star connection method

2) Steady state voltage adjustment rate: ≤ ± 1%

3) Transient voltage adjustment rate: -15% to+20%

4) Recovery time: ≤ 3.0S

5) Stable time: ≤ 1.0S

6) Volatility: ≤ ± 0.5%

7) Sinusoidal distortion rate of line voltage waveform: ≤ ± 3%

3. Frequency:

1) Rated frequency: 50Hz

2) Steady state frequency adjustment rate: ≤ ± 0.5%

3) Transient frequency adjustment rate: ≤ ± 5%

4) Recovery time: ≤ 3.0S

5) Volatility: ≤ ± 0.5%

4. Rated power factor: 0.8 (lagging)/rated speed: 1500rpm

5. Speed regulation method: electronic speed regulation

6. Starting method: DC 24V electric starting, with two sets of operations: automatic and manual. The unit itself has emergency manual starting and stopping devices

7. Excitation method: Brushless self excitation

8. Unit reliability: The unit can be used for a period of ten years or the cumulative operating time does not exceed the overhaul period, and the average time between failures can reach 2000 hours or more.

9. The adjustment range of the no-load voltage of the unit is 95% to 105% of the rated voltage.

10. The unit is equipped with a good dedicated shock absorber, and its maximum amplitude during full load operation shall not exceed 0.5mm.

11. The unit uses domestic diesel and domestic engine oil.

12. The unit is equipped with a pre heating device to maintain emergency preparedness operation.

13. There is a reliable electrical and mechanical interlocking between the unit and the mains power supply.

14. The unit has moisture-proof and anti radio interference measures.

Automatic control function:

1. Automatic start: In case of power outage, phase loss, voltage exceeding the range (380V-15%~+10%, adjustable) or frequency exceeding the range (50HZ ± 5%), the power supply will be automatically cut off after a delay of 10 seconds (adjustable), and then the diesel engine set will be started after a delay of 0-300 seconds (adjustable). The success rate of starting should not be less than 99%. The unit can be started three times in a row, with an interval of 10 seconds between the two starts. After the unit is successfully started, it should be able to operate with rated load within 30 seconds.

2. Automatic shutdown: After the recovery time of the mains power reaches 10-30 seconds (adjustable), the load is powered by the mains power, and the unit continues to operate without load. After about 5 minutes (adjustable), the automatic shutdown occurs.

3. Automatic protection: When the engine encounters the following faults, the generator set should automatically protect the shutdown and alarm (sound, light):

1) The oil pressure is too low;

2) High speed;

3) Low speed;

4) Three failed startup attempts;

5) High water temperature (for water-cooled units)

When the generator encounters the following faults, the generator set should automatically protect and shut down and give an alarm (sound, light):

1) Overcurrent

2) Short circuit of power supply bus

3) Phase failure

4) Voltage too high, voltage loss

5) Reverse power

4. Automatic supply

1) The fuel of the unit can be automatically replenished, and the fuel injection should be controlled by electronic technology;

2) Automatically charge the starting battery.

5. The unit should have an automatic timing function.
