1. Check the success rate of diesel generator set startup

Test method: The test should be conducted in a ready to start state that meets the technical requirements of the product. After each start command is given, a 50% rated load with a power of 1.0 should be suddenly applied and run for 5 minutes before stopping.

Test 100 times. The success rate of startup should be greater than 99%. Otherwise, it will be considered as unqualified.

2. Check the average interval between failures of the unit

Inspection method: Unit with cos Ф= At a rated load of 0.8 and operating continuously or accumulatively for more than 1000 hours, neither the diesel engine nor the generator should have any faults, and the components of the control circuit should not have more than two faults. Otherwise, this item is considered unqualified.

This indicator allows for assessment in actual operation.

3. Check the operation of the unit with thyristor load

Test method: Unit with cos Ф≥ A three-phase thyristor rectifier load of 0.5 should be able to operate stably at any point within the range of 10% to 50% of the rated capacity of the unit.

If low-frequency oscillation occurs, adjustments should be made to ensure stable operation, otherwise this item is considered unqualified

4. Check the linkage test of the automation unit

Inspection method: Two units should be used as primary and backup for each other, with either unit being selected as primary. If the mains power is manually cut off, the primary unit will automatically start and power will be supplied. If a fault is caused and the main unit automatically shuts down, the backup unit should automatically supply power after successful operation. To restore normal power supply, the backup unit should automatically shut down.

If not qualified, identify the cause and troubleshoot. The two units are mainly used and retested three times. If there is still one unqualified item, it is considered unqualified.

5. Check the automatic start function of the automated diesel generator set

Test method: Turn on the starting power supply, move the unit working mode selection switch to automatic, send the starting command, and if the unit fails to start manually, the unit should automatically start three times.

Test three times, and if there is one failure, double the number of retests. If there is still one failure, it is considered as a failure.

6. Check the automatic supply device of the automation unit

Test method: After the control circuit is fully connected, move the working mode selection switch to automatic manual water and oil discharge to low liquid level, which should be able to automatically replenish. When the liquid level rises to high liquid level, the replenishing should be able to automatically stop

Test three times, and if there is one failure, double the number of retests. If there is still one failure, it is considered as a failure.

7. Check the protection performance of the automation unit

Test method: Adopt simulation method for protection against low oil pressure and high cooling water temperature; Overvoltage protection adopts the method of adjusting the output voltage; Phase loss protection adopts the method of manually disconnecting one phase; Overload protection adopts the method of increasing the load.

Each protection test is conducted three times, and if there is one failure, the number of retests will be doubled. If there is still one failure, it will be considered as a failure.

8. Check the cooling water and oil heating of the diesel generator set automation unit

Test method: Connect the power supply, and if the water temperature is below 15 ℃, the heater should heat up. When the temperature reaches 50 ℃, the heater should stop heating.

Turn on the power, and if the temperature of the engine oil is below 15 ℃, the heater should heat up. When the temperature reaches 30 ℃, the heater should stop heating.
