Power system should be economic, reliable, stable and with high quality operation of the system. The major challenge is to
achieve its operation goals with overcome on its continuous problems, therefore power system automation comes into
consideration to achieve the best quality operation level of electrical power system network. Automation is defined as the usage
of machines thus eliminating human efforts to finish a task. Power system automation is the act of automatically monitoring and
controlling the power system via instrumentation and control devices. Power system automation is to incessant monitoring and
controlling of all elements and parts in the electrical network, this concept achieves by collecting all required and essential
information from field to central monitor and control location. This paper provides an overview of the automation of the
distribution power system architecture and its main components.
