Before purchasing a silent generator set for hotels, please understand the following:

For public places such as hotels and guesthouses, when usingGenerator setAt the same time, it is necessary to ensure that no noise pollution is brought to the surrounding environment, thereby affecting the residents' experience. For customers in the hotel industry, silent generator sets are a good choice. So what should you first understand when purchasing such equipment? Haixing Power staff will give you a brief analysis.

1. Determination of the capacity of commonly used silent diesel generators

The output power of the unit in long-term continuous operation can meet the maximum calculated load of the entire project, and the backup unit capacity of the generating unit should be determined according to the importance of the load. The continuous output power of a diesel engine is generally 0.9 times the calibrated power.

2. Determination of the number of commonly used silent diesel generators

The number of commonly used silent diesel generators is usually set to more than 2 to ensure the continuity of power supply and adapt to changes in the power load curve. Only with a large number of units can the number of generator units invested can be determined according to changes in electrical load, so that the diesel engine can often run under economic load to reduce fuel consumption and power generation costs. The economic operating state of the diesel engine is between 75% and 90% of the rated power. In order to ensure the continuity of power supply, the commonly used unit itself should consider setting up a backup unit. When the unit is faulty or shut down for inspection, the generator set can still supply power to important electrical loads without interruption.

3. Determination of the speed of commonly used silent diesel generators

In order to reduce wear and increase the service life of the unit, the commonly used generator set should choose a medium or low speed unit with a calibrated speed of no more than 1500r/min. The backup unit can choose a medium or high speed unit. Units in the same power station should use units of the same model and capacity so that they can use the same spare parts and facilitate maintenance and management. For projects with large load changes, units of the same series with different capacities can also be selected. The determination of the generator output calibration voltage is the same as that of the emergency generator set, which is generally 400V. High-voltage generator sets can be used for projects with large power consumption and long transmission distances.

4. Control of commonly used silent diesel generators

Commonly used units should generally be considered to be connected in parallel to simplify the main wiring of power distribution, so that when the units start and stop in rotation, the power supply will not be interrupted by parallel operation, load transfer, and unit switching. The unit should be equipped with unit measurement and control devices, and the speed regulation and excitation adjustment devices of the unit should be suitable for parallel operation. For standby generator sets that supply power to important loads, it is advisable to use automated diesel generator sets that can quickly and automatically start to restore power to important loads after an external power failure.
