Manufacturing of industrial products must be stable, but sometimes this is hampered by problems with the power supply. To compensate for their consequences, use industrial diesel generators . But only by taking into account the main features of such devices and their main varieties, problems can be avoided.
What it is?
When describing an industrial diesel generator of electricity, it is worth pointing out that such a device can be used for:
- autonomous;
- emergency;
- spare power supply for various objects, installations and premises.
Diesel generating current mount on a single welded frame … To connect it to the generator, use rigid coupling . Compression of the fuel is unnecessary in this arrangement and therefore compressors are usually not used. The power of the devices ranges from 5 to 2000 hp. with. The rate of rotation is usually not less than 375 and not more than 1500 revolutions per minute.
In any case, do not confuse special terms. So , it is correct to call a diesel generator only the bundle of a motor and an electric generator itself … The term “diesel-electric unit” is broader. It also covers the support frame, fuel tank and control and monitoring devices. And when a professional talks about a diesel power plant, he means the entire stationary or mobile installation, which also includes:
- power distribution systems;
- automatic control systems;
- protection devices;
- manual control panels;
- spare parts kits.

Above has already been mentioned about the gradation of diesel generators by power and number of revolutions per minute . But these are not the only criteria that are relevant for the selection. Synchronous installations withstand prolonged overloads well. Accordingly, they do not need additional devices for amplification at the start. However, asynchronous technology unquestionably wins when it comes to reliability, durability and minimal interference to radio communications.
Industrial power generators can supply single-phase or three-phase current . In the second case, you can vary the voltage (220 or 380 V). Systems with a single electrical phase do not differ in this flexibility.
In addition, they have less efficiency; therefore, more fuel will be consumed to power equipment of the same power. But on the other hand, there will be no additional losses during current conversion, if it is necessary to support the operation of single-phase equipment.
Difference stationary and mobile diesel generators (as well as diesel power plants based on them) is clear without additional comments. Open-type devices can only be installed in specially equipped rooms . Where dust or precipitation can get on the diesel generator, it is advisable to use closed (equipped with a casing) devices.
And for operation in especially difficult climatic conditions, it is recommended to use container generators.
It is also worth noting that some devices immediately produce high voltage currents. Other systems pre-use step-up transformers. The second option is relevant when a voltage of 6300 or 10500 V is required. Sometimes the difference is due to nuances:
- oil supply;
- cooling systems;
- fuel supply complexes;
- diesel starting systems;
- heating devices;
- control panels;
- coordinating automation;
- electricity distribution boards.
Popular models
Diesel generator demanded by consumers Perkins AD-500 . As the name implies, the device delivers up to 500 kW of current per hour. The three-phase device fully complies with the requirements for industrial installations. It can be used for both main and backup power supply. The generated current has a voltage of 400 V and a frequency of 50 Hz.
It is worth taking a closer look at the products of the company "Azimut". It manufactures diesel generators from 8 to 1800 kW. Therefore, you can choose a device for every taste and wallet. For example, the model AD-9S-T400-2RPM11 provides a constant power of 9 kW.
This three-phase system delivers a current of 230 or 400 V, with a frequency of 50 Hz, therefore it can be used without transformation even for many household appliances.
If you need 80 kW power, it is recommended to take a closer look at FPT GE NEF. The proprietary engine with a volume of 4.5 liters is designed for at least 30,000 operating hours. No more than 16 liters of fuel are consumed per hour (even in maximum mode). The increased efficiency is largely due to the well-thought-out Common Rail starting system.
Finally, it is worth considering two more interesting models. This is about Europower EP 85 TDE . This Belgian development costs over one and a half million rubles. In an hour, 14.5 liters of fuel will be pumped out of a 420 liter tank. The power of the generated current is 74 kW. The device will provide a voltage of 380 or 400 V.
And a worthy conclusion of the review will be Pramac GSW110i . An excellent Italian diesel generator equipped with 4 working cylinders. When loaded at ¾, 16, 26 liters of fuel will be consumed. Liquid cooling is provided. Other important parameters:
- electric start;
- power factor - 0.8;
- current rating - 157, 1 A;
- fuel tank capacity - 240 liters;
- open execution scheme;
- total weight - 1145 kg.
