What size generator is needed for a 15kW electric motor?

Equip a generator set to the motor. This depends on the starting method of the motor.

A diesel generator is a combination of a diesel engine and a generator (usually an alternator) to generate electrical energy, generate electricity externally, and drive electrical equipment to work. The starting methods of electrical equipment include direct start, star-delta start, soft start and other starting methods; for direct start, the required power of the generator set is 5-7 times of the load; for star-delta start, the required power of the generator set is 5-7 times of the load. 3-5 times. In case of soft start, the required power of the generator set is 1.5-2 times of the load.

If the poster’s 15 kW motor starts with a star-delta start, the power of the supporting generator set must be at least 15*3=45 kW. Others can be converted according to the above multiples.

What is the maximum load of a 15kW diesel generator?

Assume that the fan blades are installed once every 60 seconds. A 1,500-kilowatt wind turbine generates 25 kilowatt-hours of electricity per revolution.

The calculation method is as follows:

The power generated by a 1500kW generator in one hour is 1500KWH, which is 1500 kilowatt-hours of electricity

1500 kilowatt-hours of electricity/hour ÷ 60 revolutions/hour = 25 kWh/circle.

Extended information:

< p> Degree is also called kilowatt hour, which means that a 1 kilowatt generator generates 1 kilowatt hour of electricity for one hour.

Kilowatt (Kilowatt), an early unit of electrical power, now has a tendency to be extended to the unit of power in the entire field of physics. In electricity, kilowatt-hour is exactly the same as degree, but they have different names.

1 kilowatt = 1,000 watts (Watt) = 1000 joules (Joule)/second (Second).

1 kilowatt = 1,000 Newton meters per second (N m/s)

1 kilowatt = 0.239 kcal/s

1 kilowatt = 1.36 horsepower

A kilowatt-hour or kilowatt-hour (symbol: kW·h; often abbreviated to degrees) is a unit of energy measurement that represents the energy consumption of an appliance with a power of one kilowatt after one hour of use. energy consumed.

The unit "kilowatt hour" is mainly used to measure electricity, because "kilowatt hour" is easier for the public to understand than joules, and it is easier to convert into hours of electrical appliance use. On the other hand, the unit measurement of joule is too small compared to "kilowatt hour", making it difficult to calculate. In mainland China, some public institutions also use "megawatt hour" instead of "kilowatt hour" on their charge sheets. In Chinese, "kilowatt" is sometimes written as 瓩.

1kW·h = 3,600,000 joules = 3.6 million joules.

The physical meaning of 1 kilowatt hour is: the electrical energy consumed by an electrical appliance with a power of 1 kW for 1 hour (or the work done for 1 hour).

One kilowatt per hour is equal to:

3.599712×10 joules;

1.3596112 metric horsepower per hour;

1.3408927 imperial horsepower per hour hour;

8.599712023×10 kcal.

Theoretically, it can be 15X1.2=18KW within 2 hours of working time. This only works when the power factor is 1 and the machine is new.

Generally it is 15X0.8=12KW.

In actual work, it is 15X.0.65=9.75KWH. Because there are too many possible factors in practice, such as distribution, startupability, etc.
