AB  - In most of the developing countries, like Iraq, electrical power fails frequently which is a considerable
problem facing these countries. The stand-alone generator sets have become in the forefront of the backup aid
to maintain the availability of electricity for residential areas under the situation of sudden electrical power
shutdown, fluctuation and failure. In Iraq, the stand-alone power generating sets (250-400 kVA) are known as
Zone Generators (ZG) which supplies electricity to a limited area (Zone) of 40-60 houses in case of the National
Establishment of Electricity (NEE) absence. Private Generator (PG) which is a small mobile generator (1-4 kW)
is used to supply electricity to a single house in emergency cases (when both NEE and ZG are absent), this type
of generators is operated manually by the owner. This study tries to establish a humble automated solution for
supplying a load (residential) with electricity from three sources, the first one is the NEE, the second is the ZG
in case of NEE absence and the third source is the PG when both NEE and ZG are absent. A Programmable
Logic Controller (PLC) is used to control an Automatic Transfer System (ATS) to supply the load with the
available source. This automated system protects the load from over voltage and under voltage hazards which
may occur during the operation, it also monitors the availability of the three phases of the main source (NEE).
