Types of backup power systems

Types of backup power systems

In the XXI century, despite the fact that global progress has made a huge step towards solving the problem of interruptions in power, unfortunately, the problem is still very relevant, which is why many are thinking about what is the system of backup power?

Autonomous generator helps you to not depend on power problems, it is indispensable in emergency outages and where there is no electricity at all -.. The outdoors on a construction site, etc.

When the accident at the power lines while eliminating breakageor circuit can be even a few days, which is why a backup power supply - it is one of the main needs.

To understand how to select the power supply, it is necessary to determine the conditions under which people can be without, electricity.

By trip duration can distinguish 4 types:

  • Micro off - occur if the transmission line has malfunctioned or because of transients.These trips can last from a couple of seconds to a couple minutes.Despite its brevity, the house can turn off electrical
    appliances that can also lead to their closure;
  • Short trip - are due to outages on the package transformer substation.Such an interruption occurs in the power supply, if the power line is overloaded, short-circuited, or for short-term work.off times may vary from 1 hour to 12 hours;
  • Medium-off - it occurs when the power line has undergone a major accident, or is short-circuited to the high-voltage power lines.off times may vary from 12 hours to several days;
  • Long off - are due to massive damage to power lines and substations complete transformer due to the hurricane, ice storm, natural disasters.Due to the large scale of damage off times may be up to several weeks.

Based on the damage specific to your area, and should be selected backup power system.

In modern stores very well provided with various types of self-contained generators: they can run on gasoline, diesel, gas, are portable and stationary, inverter, with automatic or manual start.

petrol gas or diesel generator

One of the best budget options for backup power systems - is the acquisition of an autonomous power - generator.

generators are diesel, gas and gasoline.

Petrol - stand-alone device that is designed to provide a current of electrical appliances and equipment.The generator is equipped with an internal combustion engine.

One of the main advantages of buying such a device - it's low price, ranging from 4 to 10 thousand, of course, there is also much more expensive models.

It is easy to use, can work in freezing temperatures down to -20 degrees, the noise from it is not very loud, has a compact size and low weight.

Such a generator can provide back-up power supply of a country house, an apartment.It can also be taken during trips into the countryside.

Petrol will not be able to provide continuous constant power supply, it is recommended to use in case of emergency, the work should not exceed 5-7 hours, otherwise the engine may overheat, which will inevitably lead to failure.

Powered Generator 92 gasoline, which is also in continuous use will cost "a lot of money."

If the generator must be equipped with ventilation space, since in the process of combustion of fuel in the engine exhaust gases are formed...

So, for backup power in case of emergency outages, gasoline generator will be a great solution.

diesel generator can provide uninterrupted power from a few days to a few weeks.

Life had longer than a gasoline generator.

choosing a generator, it should be noted that the diesel fuel is much cheaper than gasoline fuel, and with constant use of fuel generator will go very much.

the minuses of the diesel generator can be noted: the high price of a stand-alone power plants - from 20 thousand to hundreds of thousands.

case of breakage of the unit repair and replacement parts will cost as cheap.Also, one important fact is that the diesel generator high noise while working.

For powerful diesel generator need to soundproof a room with a ventilation system.Unlike gasoline generator, the combustion of diesel exhaust is much more toxic vapors.

most optimal solution - is the installation of the generator outside the home.But even here there are pitfalls, because the diesel generator will not work at temperatures below -5 degrees.

for use in the winter time it is best to get a special protective cover.

acquisition of such a generator would be reasonable for the room with a lot of electrical appliances.

Gas generator - running on natural gas.This type of uninterruptible power supply is not widely applied.

It is economical and fuel is cheaper for him than gasoline or diesel fuel, but at the same time, the price of such a setup is very high.

for the gas generator must be connected to the gas supply system, which is not always convenient.

inverter generator - perhaps the most progressive form of the generator, which provides backup power supply.

It has several advantages:

  • light weight (several times smaller than a conventional generator);
  • convenience;
  • economy.

Inverter generators run on gasoline or diesel, but the fuel consumption have decreased by 30-40%.

Application inverter generator is recommended for backup power and consumer electronics.

Fuel economy in such generators is due to the automatic speed control.By reducing the load generator automatically switches on power saving mode.

battery system for backup power

batteries are electric drive.The chemical processes that take place within them, allow him to work in the mode of cyclical discharges and charges.

batteries charged by passing electric current through it.

Charging batteries should not forget that they are heated in the process of feeding, it is especially important when fast charge mode.

Therefore, batteries should be charged at a distance from each other for ventilation.Also, batteries can be combined into a one-piece, this type is called a battery.

main criterion when selecting such a source of autonomous power capacity is considered.Capacity - the maximum amount of charge that can take batteries.

choosing standalone batteries, first of all, you need to pay attention to the number of charge and discharge cycles - the higher it is, the better.

choose batteries with a long service life for the backup power supply.

necessary to take into account factors such as self-discharge is about 3-5% per month, and the storage conditions of 20 degrees is optimal.

Inherently self-contained batteries are a consumable item and due to its high price using them for backup power almost common.

autonomous power supply system will be a good solution in the struggle with the unpleasant situations of power outage, which can happen at the most inopportune moment.

Using backup power supply system, you can not worry about how to disable the heating system, water pumps, security systems, boilers, and much more.
