- W1176929965 abstract "The SMARTGRID is a general term for a series of infrastructural changes applied to theelectric transmission and distribution systems. By using the latest communication andcomputing technology, additional options such as Condition Monitoring can now beimplemented to further improve and optimise complex electricity supply grid operation.Lifecycle optimisation of high voltage assets and other system components in the utilityprovide a case in point. Today Utility experts agree that application of scheduledmaintenance is not the effective use of resources. To reduce maintenance expenses andunnecessary outages and repairs of equipment due to scheduled maintenance, utilities areadopting condition based approaches. Real time online monitoring of substationparameters can be achieved by retrofitting the existing substation with SMARTGRIDtechnology. The IEC 61850 is a common protocol meant for Substation AutomationSystems, designed for the purpose of establishing interoperability, one that allmanufacturers of all different assets must comply with. This thesis advocates the estimationof bandwidth required for monitoring a substation after retrofitting the existing substationwith smart communication technologies. This includes establishing a latest wirelesscommunication infrastructure from the substation to the control centre and evaluating theperformance modelling and simulating the physical layer of communication technologiessuch as WIMAX (IEEE802.16) and MICROWAVE point to point using MATLABSIMULINK and RADIO mobile online simulation software. Also, link budget of thesatellite communication for the same application is calculated. Satellite communication inthis case is considered as a redundant or back up technology to ensure that thecommunication between entities is continuous. On performing the simulation on differentenvironments the results prove that the selected protocols are best suited for conditionmonitoring. The measured Latency could be the best approximated value which complieswith the current objective. However the white noise that exists in the substation hassignificant hazard with respect to the security of the wireless network. To compensate thisconstraint whole substation is hard wired by means of plastic fibre optics and the data sentto the base station located near the substation." @default.
