Permanent supply of electricity isa 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 service infrastructure, moving at times of need.
General information on mobile power plants
The need for electricity can arise ina 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 energyequipment of this type is precisely the possibility of convenient transportation. As a rule, the machinist 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 to the carrier platform of the station and carries out its movement.
The principle of operation of stations
The work process is implemented according to the principle of generationenergy. 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.
To burn fuel, a specialcamera, and the engine in the process of carrying out the conversion of thermal energy into electricity. Most often the mobile power plant has in the power unit a piston group and a crank-and-rod mechanism that 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 representedalternator 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
The equipment differs according to the type offuel and the way of transportation. As for the initial energy source, it can be liquid or gaseous. Typically, a liquid fuel is used - this diesel or gasoline. Gas is used where it is possible to connect to the main line.
Вообще, применение газа – это дешевый способ generation of electricity, but not always available, since the movement of 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.
Typical mobile diesel power stationwins at the expense of power, but costs more in the content. 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 equipmentis the possibility of providing an autonomous power supply. It is not only the supply of objects remote from the central power lines, but also the function of reserve supply. For example, such an installation would be appropriate at the dacha, if in the area there is an unstable operation of the power grid. The very operation of mobile power stations can bring a lot of problems. First of all, such units spend a considerable part of 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 talk aboutpositive 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 plants can ensure the work of not only the construction tool, 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 severalparameters. 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 220 V unit is suitable, 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 sourcesoften 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.
