Abstract
Reliable electricity supply is essential for development. As a result, demand for
electricity has continued to increase globally, occasioned by the fact that
electricity is highly portable and can be transformed from one form to another to
meet needs. In Nigeria and most developing countries, electricity supply from the
public utility is not only insufficient but highly erratic. The effect of this is adverse
on critical and sensitive infrastructure that depend on uninterrupted power
supply. Hence, many domestic, industrial and commercial consumers are
compelled to acquire one form of alternative source of power supply or another.
With this however, when different power schemes are interconnected, there
arises the challenge of switching between the power sources not only smoothly,
but in a manner that optimizes their use. Solving these challenges forms the focus
of this work. This design monitors three independent power sources: Utility Grid
of Power Holding Company of Nigeria (PHCN), solar and generator and engages
them following preset conditions in a microcontroller. A software program in
assembly language drives the microcontroller. Preference is given to the PHCN
line, but in the event of failure or abnormal conditions in the PHCN line, the
system will effect a changeover automatically to the solar source through
contactors, provided the output of the solar source is acceptable, else the system
will initiate the starting of the generator and transfer of load to same. This system
finds application wherever there is unreliable power supply and interconnected power schemes.
