Before purchasing a silent generator set in hotel occasions, please learn about the following contents

For public places such as hotels and hotels, while using generator sets , it is necessary to ensure that no noise pollution is caused to the surrounding environment, which will affect the residents' stay experience. For customers in the hotel industry, silent generator sets are a good choice. So what should we understand first when purchasing such equipment? The staff of Haixing Power will give you a brief analysis.

1. The capacity of commonly used silent diesel generators is determined

by the long-term continuous operation of the unit. The output power can meet the maximum calculated load selection of the entire project, and the capacity of the generator set backup unit should be determined based on the importance of the load. The continuous output power of the diesel engine is generally 0.9 times the calibration power.

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

The setting of commonly used silent diesel generators is usually more than 2 units to ensure the continuity of power supply and adapt to changes in the applied electrical load curve. Only when there are many units, the number of units that can be determined according to the changes in the power load can be determined, so that the diesel engines are often operated under economic load to reduce fuel consumption and reduce power generation costs. The economic operating state of the diesel engine is between 75% and 90% of the calibration power. In order to ensure the continuity of power supply, the commonly used units should consider setting up backup units. When the unit fault maintenance or shutdown inspection is carried out, the generator set can still meet the continuous power supply to important power loads.

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

In order to reduce wear and increase the service life of the unit, commonly used generator sets should choose medium and low-speed units with a calibrated speed not exceeding 1500r/min, and their spare units can be selected as medium and high-speed units. Units of the same power station should be selected from the same model and capacity to use the same spare parts for easy maintenance and management. For projects with large load changes, units with different capacity can also be selected in the same series. The determination of the output calibration voltage of the generator is the same as that of the emergency generator set, generally 400V. In some projects with large electricity consumption and long transmission distance, high-voltage generator sets can be used.

4. Commonly used silent diesel generators

should generally be considered to be able to be carried out in parallel to simplify the main wiring of the distribution, so that when the unit starts, stops and rotates, the power supply will not be interrupted by paralleling, transferring loads, and switching units. The unit should be equipped with unit measurement and control devices, and the unit speed regulation and excitation regulation devices should be applicable to the requirements of parallel operation. For backup generators that supply power to important loads, an automated diesel generator set should be used to quickly and automatically start after the external power supply fails and power is restored to restore power supply to important loads.
