How many kilowatts of generator sets does the hotel use?

How many KW generator sets the hotel will use mainly depends on the total power of the hotel, which is calculated according to the total power of the hotel.

For example, if the total power is 200KW, it is about 250 kW-300 kW to buy a diesel generator set.

The optimum power of diesel generator set is 75%-80%, which can be used for a long time and reduce faults.

Specifically, it is necessary to calculate the total load power that needs to be considered, that is, the generator sets are basically purchased as backup power sources, that is, the sum of the equipment loads that the hotel must bear after power failure; Generally, standby fire power supply and emergency lighting are mainly considered; Including elevators, fire pumps, room lighting and other loads that need to be considered; In case of power failure, the central air conditioner is generally not considered, and several elevators can be stopped appropriately (only 1-2 standby is considered).

Brief introduction of generator set:

When the volume of diesel generator set decreases, the temperature of generator set rises rapidly, reaching the ignition point of diesel. The diesel oil is ignited, the mixture burns violently, and the volume expands rapidly, pushing the piston downward, which is called' doing work'. Each cylinder does work in turn according to a certain order, and the thrust acting on the piston becomes the force to push the crankshaft to rotate through the connecting rod, thus driving the crankshaft to rotate. Using the principle of' electromagnetic induction', the generator will output induced electromotive force through a closed load loop to generate current. Only the most basic working principle of the generator set is described here. In order to obtain available and stable power output, a series of diesel engine and generator control and protection devices and circuits are needed.
