Mobile power station: description, principle of operation, types and reviews

Constant supply of electricity is a classic task in the implementation of energy infrastructure. Cable lines distributing transformers and current converters are mandatory components of similar projects. But far from always consuming objects need exactly regular energy supply. Partly because of the specifics of their own operation, and partly because of the non-permanent location. In such cases, a mobile power station can be used that replenishes energy consumption objects at certain intervals or enters their serving infrastructure, moving at times of need.

General information about mobile power plants

The need for electricity can occur in a variety of conditions. For example, on a construction site remote from main power lines. Or in the places of repair work on communication networks, which are also at a great distance from civilization. In these cases, a mobile power station is used, which ensures the supply of remote consumers. There are small power stations of the order of 10 kW, as well as production units up to 100 kW and above. Depending on the needs of the consuming object, the appropriate power station is selected.

A feature of mobile power equipment of this type is the possibility of convenient transportation. As a rule, the driver of a mobile power station is responsible not only for connecting and further maintaining the operability of the unit, but also for its movement. Usually, for such needs, a car is used that is hooked up to the carrier platform of the station and carries out its movement.

The principle of operation of stations

The work process is realized according to the principle of energy generation. In this segment, diesel electric generators are the most common, since they allow achieving a high degree of autonomy. From the same driver is required only to supply the equipment with liquid fuel to generate heat.

A special chamber is provided for the combustion of fuel, and the engine, during operation, converts thermal energy into electricity. Most often the mobile power plant has in the power unit a piston group and a crank mechanism, which activates the crankshaft. As a result, the torque rotates the rotor of the generator, which leads to the development of the required resource.

The electric machine itself can be represented by an alternating or direct current generator. In general, we can talk about the three working stages of power generation - fuel combustion, the activation of a mechanical group and the generation of current from the physical effort of the engine.

Varieties

Equipment differs according to the type of fuel used and the mode of transport. As for the initial energy source, it can be liquid or gaseous. Typically, liquid fuel is used - the diesel or gasoline mentioned . Gas is used where there is a possibility of connecting to the main line.

In general, the use of gas is a cheap way of generating electricity, but not always available, as moving gas cylinders requires maintaining a high degree of safety. As for diesel and gasoline, the choice of fuel depends on the type of power plant used in the station .

A typical mobile diesel power plant wins at the expense of power, but costs more in maintenance. Also, mobile generators are divided according to the mode of transport. There are self-propelled stations, trailed, block-transportable and portable.

Advantages and disadvantages of mobile power plants

The main advantage of this equipment is the ability to provide autonomous power supply. It is not only the supply of remote objects from the central power lines, but also the function of reserve supply. For example, such an installation would be appropriate at the dacha if an unstable operation of the power grid is observed in the district. The very operation of mobile power plants can bring a lot of problems. First of all, such units are spent most of the time in inactivity, therefore, periodic implementation of technical preservation measures is required. In addition, mobile power plants need constant maintenance of functional and sensitive elements - it is enough to note the details of the power plant.

Feedback on the operation of mobile power plants

Basically, users of such aggregates speak about the positive experience of their application. In some cases, mobile stations become the only solution for power supply problems. Owners point to the ease of handling such equipment and the high return on energy potential. That is, small portable generators can not compete with such stations because of low power reserves. The generated electric power of mobile power stations can ensure the work of not only the building instrument, but also individual production lines. The main thing is to choose the right model.

How to choose a mobile power plant?

The choice should be based on several parameters. The main capacity will be power and tension. So, 7-10 kW will suffice to supply a small house, and 30-50 kW may be required to operate the plant in the industrial sector. It is important to take into account the tension. For domestic purposes, the unit is suitable for 220 V, and 380-volt mobile power plants are usually used in production. The price in the first case is about 150-200 thousand rubles, and industrial power plants are estimated at 300-400 thousand.

Conclusion

The concept of standby power supplies is often criticized for modest performance in long-term operation modes. In other words, the working period is reduced to a minimum, which is enough only to support the operated facilities in emergency condition. In turn, the mobile power plant can work for weeks and months without interruption, provided that the site has the possibility of its regular supply of fuel. Moreover, modern power generators are actively supplemented with automatic controls. This allows not only to use the resources of such aggregates for a long time, but also to leave them working without constant operator control.
