Influence of Distribution Automation Construction on the Power Supply Reliability

This paper proposes four models of distribution automation system,namely fault locating system,local feeder automation system,centralized feeder automation system,and dispatching and distribution automation system.The functions and the influences of these four models on power supply reliability are studied.And the power supply reliability of distribution network in different automation models is evaluated using the network-equivalent method.By comparison of the results,it offers some suggestions on choosing the distributed automation model for different areas.
