Over the past decade the electrical power industry has undergone many changes. Vertically integrated utilities have been transformed into smaller companies. Transmission and Generation systems are increasingly relying on advanced digital and computational elements for protection and control of their substation and transmission. The Substation Control and Monitoring System (SCMS) is a major part of advanced power system management. Better control and faster performance are achieved by performing local tasks in the substation. This system provides better protection of valuable substation equipment.
The SCMS accommodate any existing intelligent electronic devices (IED) and fully integrate new technologies and equipment for control, protection, disturbance recording, and condition monitoring. This system is fully capable of being integrated with the Distributed Management System (DMS).
This report deals with use and operation of the Substation Control and Monitoring (SCMS) which is a system that monitors and controls breakers, generators, transformers, surge arrestor monitoring, and a host of other secondary equipment monitoring.
Chapter one in the report discusses the importance and the general definition of the SCMS, whereas chapter two is more focused on the utilizations and operations of the SCMS. An analysis was made in chapter three using life-cycle analysis, maintenance task analysis, and level-of-repair analysis. Thereafter an attempt was made to identify some of its logistical problems and weaknesses in a bid to proffer solutions to such problems raised. Acknowledgments
