    Dear Salomaa,

    I am not sure if you need the information in Arabic or English, but you can refer to (
    http://en.wikipedia.org/wiki/Standby_generator ) where you can find a general description of the Standby generator system, as follow:
    A standby generator is a back-up electrical system that operates automatically. Within seconds of a utility
    outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. After utility power returns, the automatic transfer switch transfers the electrical load back to the utility and signals the standby generator to shut off. It then returns to standby mode where it awaits the next outage. To ensure a proper response to an outage, a standby generator runs weekly self-tests. Most units run on diesel, natural gas or liquid propane gas
    .
    Automatic standby generator systems may be required by building codes for critical safety systems such as elevators in high-rise buildings, fire protection systems, standby lighting, or medical and life support equipment. Residential standby generators are increasingly common, providing backup electrical power to HVAC systems, security systems, and household appliances such as refrigerators, stoves, and hot water heaters.

    -----------------------------------------------------------------------------------------------------------


    More Elaboration:

    As an example for the building codes requirements, NFPA (National Fire Protection Association) which is the most applicable code in construction industry, asks for providing standby generator sets (we call it “gen.set”) to secure the essential power for firefighting /protection system (Firefighting water pump set jockey pumps), fire alarm system, life safety systems (such as stair pressurization systems and smoke extract systems), Security system, Occupant warning system & PA (Public Adress) system, in addition to fireman lifts and in case of fire and passenger emergency lifts in case of power failure.

    There are some life safety devices works with central battery system or self-contained batteries (recommended to be monitored by the BMS (Building Management System)) or standalone system.

    Furthermore, in hospitals it is essential and mandatory to have back up power for all life support systems and surgery rooms.

    System Description and components:

    It depends on project requirement and design intent, but normally the system comprises of a diesel engine, alternator, Day fuel storage tank, Bulk Fuel Tank, Engine cooling radiator and fan and or facilities for remote cooling, cooling air inlet and discharge with attenuators, low voltage and control cabling, output switchgear, exhausts system and an anti-vibration system.

    I hope that the above information will help.
