Diesel power plants are the installations that generate electrical current. They are used as an individual source of power supply for country houses, for small private enterprises. Diesellelectric power plants are widely used and as a reserve in case central sources do not work. Our article is dedicated to these units.

Constructive elements of the power plant diesel

The center of such an alternative source of power supply is a diesel generator, which includes:

• engine on diesel fuel;
• electric generator;
• cooling system;
• lubrication system;
• fuel supply system;
• control panels.

In addition to this main node, diesel electrical installation is equipped with systems:

1. Cooling diesel, which includes pumps, pipelines, tanks.
2. Eating fuel engine. Include fuel tanks, pumps, pipelines.
3. Responsible for lubricating the engine with such necessary elements like oils oil, radiators, oil-carrying, pumps.
4. Running diesel engine. This includes a starter electric, rechargeable battery, generator for charging or air compressor, pipelines, launchers valves.
5. Designed for heating a diesel engine, including heaters, ventilation and heating elements, coils, lamps.

Another power plant is equipped:

• control shields with an appropriate cable set;
• distribution shields;
• rechargeable battery and rectifiers.

What to pay attention to when choosing

When choosing a source of power supply, you should think about the following:

1. What kind of design you want to have: mobile or stationary.
2. What power of the diesel power plant will suit you.
3. How much fuel consumes the unit.
4. What is included in the kit (automation, container, casing).

Tip: If there is no electric heating or electric stove in the kitchen, then you will fully suit the power of 5 kW, but when at least one of two is present, then a power plant with a capacity of 10 kW should be selected. When choosing, navigate not at the maximum power, but on the nominal one.

Diesel power plants. "Pros and cons"

In favor of choosing this autonomous power source, the following facts say:

• DEZ is the most economical option. In comparison with gasoline consumes the energy carrier less than 40%;
• it works steadily;
• have high performance.

The main disadvantages of DES:

• launch problematic at low temperatures;
• the need for winter fuel in cold climate conditions;
• a relatively small frequency period.

Consider when choosing: the efficiency of the diesel power plant is particular from the division of the tank tank to the flow of diesel fuel per hour. All indicators are taken in l. with.

Types of DEZ

All power plants operating on diesel fuel, depending on the design are divided into 2 types:

1. Stationary. The operation of diesel power plants of this species is carried out in rooms in close proximity to the object, for the power supply of which they were intended.
2. Mobile, operating in the temperature range -50- + 40 degrees C and equipped:

• diesel electrical unit;
• power distribution;
• wardrobe with automation;
• remote control;
• heating with ventilating installation;
• batteries and rectifiers;
• a set of cables for connecting;
• fire extinguishing agents;
• tool.

To move mobile diesel power plants, autographs are used:

• 1-axis for aggregates with a capacity of up to 10 kW;
• 2-axis - over 20 kW.

According to the functions of the DES, there are:

1. Emergency. Install them where pauses in the supply of electricity are not allowed.
2. Reserve. Used in the event of a breakdown of the main source or as a reserve, when voltage is not supplied from the stationary network for some reason.
3. Main. Used in places where there is no centralized power supply and inappropriately insert it.

Separation of diesel power plants by execution

In its execution, diesel power plants are:

1. Synchronous, asynchronous. More reliable and durable first, but they do not cope with long overloads. The second tolerate overloads well.
2. One and 3-phase. The efficiency of the 3-phase above, they produce voltage and 220 and 380V, and 1-phase only smaller.
3. Open, designed to work in the room.
4. Enclosed in the casing. Usually - this is mobile equipment.
5. Container intended for operation in the area with a harsh climate.
6. High-voltage, having a high-voltage generator. There is no boost transformer.
7. High-voltage with a raising transformer, allowing to obtain a voltage of 6.3 kV, 10.5 square meters.

Principle of operation of diesel power plants

A diagram of a diesel power station 0.4 kV with 1 generator looks like this:

On this scheme:

• I and II - groups of outgoing lines;
• III - network entry group;
• IV - control panel;
• V - voltage regulator;
• 1 - automatic switches;
• 2 - switches;
• 3 - generator current transformers;
• 4 - network entry current transformers;
• L1 and L2 - Lines of outgoing;
• CH - own needs.

The principle of the unit is as follows:

• the engine performs mechanical work;
• the generator converts mechanical work into electricity.

The following processes occur:

1. With the ignition of diesel fuel in the internal combustion engine, the gases are expanding. The energy that occurred at the same time is converted into mechanical and rotates the crankshaft.
2. The rotational moment is transmitted to the AC synchronous generator rotor. As a result, an electromagnetic field appears.
3. It provokes the occurrence of induction alternating current in the generator winding. The current receives the consumer.

Interesting to buy a diesel power station, it is necessary to study the market offers.

Overview of popular models of diesel power plants

Diesel power plants, photos and descriptions of which are placed below, are released by well-known manufacturers and are distinguished by reliability and quality.

Cummins diesel power station

The American company Cummins has long been recognized as a leader in the production of diesel power plants.

The benefits of Cummins diesel power plants are indicated by the following facts:

1. All nodes and details design and produce company specialists.
2. Basic equipment DEZ extended. In particular, copies supplied to Russia have such a fueling system that allows the use of fuels of not the highest quality without prejudice to operational parameters.
3. The diesel engine installed on Cummins has water cooling and an additional protection and control system and refers to environmentally friendly equipment.
4. CUMMINS power range is 8-2400 kW.

Power plants diesel SDMO

Releases equipment both stationary and mobile with high technical characteristics from France SDMO ELECTRIC. Power 0.9-2250 kW. Is different:

• the presence of a unique management system;
• the functionality of the console, which has more than 150 parameters:
• ecology;
• endurance.

DES from Tessari Energia

Tessari - diesel power plants, the price of which is quite justified by high quality. They produce them only in Italy. Different with excellent operational parameters:

• it starts as soon as the signal is received about the absence of voltage in the network;
• it stops immediately after the resumption of central power supply.

Character:

1. Engines from authoritative manufacturers, such as Volvo Penta, Iveco, Perkins, Cummins,  MAN.
2. A unique management system capable of monitoring DEZ.
3. Do not require maintenance by brushless generators of Italian manufacturers or Mecc Alte, or Marelli. They are well adapted to overloads.

Made in the following options:

• open - for installation indoors;
• placed in the casing - for external use;
• on the trailers for the possibility of transportation.

Power of diesel power plants Tessari - 15-3,000 kW.
