Comprehensive Study on Central Control Management of a Power Distribution System

The purpose of this study is to develop a familiarity with the central control and management functions, the nerve of any power system. The paper considers a distribution system and emphasizes on distribution management system (DMS). DMS uses state estimation to maintain the healthy working condition of the system. It plays a very important role in the control of the distribution system, as the level of control that possible is restricted owing to the specifi c structure of distribution networks and penetration of real-time monitoring and control facilities. So far, the level of SCADA implementation in distribution networks has controlled around 10% of switching devices and has been limited to circuit breakers at the larger primary substations. The four main functions of the DMS have been discussed focusing mainly on Outage Management.
