Zoe Dydynskaya autonomous power has long ceased to be the preserve of large enterprises and are increasingly used in private suburban homes. It is no secret that most of the existing villages and cottage settlements electrical network does not hold water because of deterioration, lack of power fluctuations and power failure. Some holiday homes are under construction and does away from power lines. In this regard, before the homeowners there is the problem of providing a reliable electricity supply dwelling. The solution is to create a system of uninterrupted power supply to the house on the basis of autonomous power. Factors for choosing As practice shows, the choice of battery power to keep in mind several key aspects. Among them: the power generator, safety, fire safety, low noise, the possibility of battery operation, automatic start and, of course, price. First of all, you need to determine, as a source of electricity - the main or reserve - will operate your installation. This factor depends on the presence or absence of close to your home network backbone. Another important point - the right choice of generator power. Depends on the capacity and quality of the unit, and its cost. That is why this feature is worth paying close attention. But keep in mind: many manufacturers in the directories give the so-called "maximum power". So, this option provides short-term operation of the unit (from several seconds to several minutes). Actual rated power is usually much lower. When choosing recommended to take into account such factors as place of use, duration of operation of the plant, environmental safety, etc. The elements of the device main elements of battery power is fuel engine and an electric generator. The engine is considered the "heart" of the installation, because it was his resource defines the term "life" of a particular plant. In most cases, the class is defined by its engine power, or rather the lifespan. Thus, the professional petrol engine uptime before the first potential failure of thousands of hours, while at the amateur - only hundreds. But diesels are in units usually used professional. The alternator produces electricity. Depending on the type of generator mini-power plant copes better with certain tasks. According to various parameters of the generator can be divided into one-or three-phase, synchronous and asynchronous. More on this will be discussed in the next chapter. Other fuels - different forms today in the domestic market presents a huge amount of autonomous power. How to choose a system best suited to your home? Perhaps the only way - at least briefly consider each variety. First of all, self-contained power divided by fuel type on which they work. The most common gasoline and diesel generators, gas power plants are also popular, relatively new, but interesting solar electric power systems. Gasoline Power - is a simple and cost-effective solution to the problem of sudden power outages. Lightweight, compact, low noise level and lower, compared to diesel, the price is predetermined the success of these plants. Gasoline generators are often equipped with electric start devices that allow them to automatically turn on when you need to activate an alternate power source. Gasoline autonomous power divided by type of internal combustion engines: There are two-and four-modification (the latter - the most common). Among the diesel generator units most in demand of medium and high power. Low-power installation is rare, since the price is high enough, but the noise level is high. Diesel generators can operate at different speeds. Vysokooborotisty units (3000 rpm) are smaller in size and weight. However, they are also characterized by high noise levels and a shorter life MTBF. If you purchase a stand-alone diesel power to generate electricity for a long period, a more preferable choice of slow-speed versions (1500 rpm). Stand-alone power plants using natural gas or LPG have their advantages. Importantly - cheap fuel, for which acts as natural gas and gas with low calorific value, low methane content and low degree of detonation. Even when used as a backup fuel gas mixture of propane and butane, cost per unit of power generated by the gas installation is less than diesel. Another important advantage over the diesel engine plant - environmental safety and fewer harmful emissions. By cons of such plants, some experts consider a number of difficulties in installation and operation. An alternative to traditional energy sources are gradually becoming a solar power system. Such plants are essential elements of which are modules made from silicon, no longer considered exotic and are recognized as unparalleled in environmental and resource base. Solar energy system is not yet very well represented in our market, but increasingly used as a stand-alone power supply for the full country house, and as a backup source if the main power grid. These systems are able to produce different amounts of electrical energy and can be designed to load, depending on the number of household appliances. Advantages of solar power plants: ecological, silent, the use of "free" sunlight, lack of maintenance is required. The system can be upgraded with additional modules, thereby increasing its power. Less of such devices is obvious: the number of sunny days in our region is limited. But the solution to this problem lies in the fact the solar generator: the sun's energy not only converted into electricity, but is stored in batteries. Stored energy can be used on cloudy days. In addition, solar power can be used in conjunction with other types of generators. Dividing by other attributes the following characteristics, concerning the independent power plants, the number of phases produced by stress. Stand-alone generator sets to produce mostly one-or three-phase voltage. For single-phase generators that produce alternating current voltage of 220 V / 50 Hz, you can use only single-phase loads, whereas a three-phase (380/220 V, 50 Hz) - and those, and others (on the dashboard there are appropriate outlets). Typically, for domestic use, power limited number of appliances or lighting the house and grounds enough for a single phase, whereas in an industrial environment requires three-phase power source. Speaking on the scope of independent generators of electricity, it is worth noting their division into synchronous and asynchronous. Synchronous generator is structurally more complex: for example, it has on the rotor are coils. Induction generator are simpler: it resembles an ordinary flywheel rotor. In addition, synchronous and asynchronous generators differ in their abilities. Synchronous generators are productive when working with devices of the inductive nature of consumption: welding machines, electric saw, pumps, etc. This is due to the ability of synchronous generators for one or two seconds to give a current, which in strength several times greater than nominal. Asynchronous generators are more simple in the device and easier to maintain. Preferable to use the generators of this type for domestic needs, as the output voltage asynchronous generator differs by the absence of nonlinear distortion, which is important for normal functioning of electronic equipment such as computers, kitchen appliances, lighting elements, etc. As a way to run a self-contained power divided by the model with manual start , electric and automatic start. Power plant with a starter does not require any physical effort other than pressing the right buttons. If there is only the manual run, will turn the knob or pull cord. Electric is required if the stand-alone generator need to install an automatic startup. The appointment of such a system - startup and shutdown at the right time without human intervention. For example, in your cottage lost electricity. Automation battery power understands this and using the electric starter and the battery starts the generator, providing the work necessary equipment. For stand-alone power plants provide many additional options. In this regard, we can distinguish two main groups of power generators - be combined jacket and without it. Special enclosure, which provides reliable protection against corrosion of the unit allows it to operate at atmospheric precipitation and significantly reduces engine noise generator. Gasoline-electric power stations in the main casing is not needed - these units and both work quite quietly. More in demand covers the use of diesel power plants. If it is a regular operation of such a generator outdoors near the people, housing is a must. Perhaps the only negative acquisition unit with the housing - it is a sizeable increase in its price. Conclusions The main advantages of autonomous power stations - the independence and comfort. With the help of these units are usually simple to use, you can save heat, light and comfort in your holiday home. Without worrying about possible interruptions or outages, and sometimes not at all tied to the main power grid, you can enjoy all the benefits of civilization in his country house. If you are serious about the choice of the unit and use the services of professionals when it is installed, it will be long to provide all seven of its own production of electricity. We hope that the above information will be sufficient to enable you to evaluate the proposed range in our region and outline the direction of their preferences. And for more advice and help in the final selection is better to contact the professionals.
