The most recent genera-tion of InformationTechnology bringsprotection and controIterminals to the utilitypersonnel, wherever theyare. This also bringsbenefits in terms ofsubstantiaI cost savingsand new ways of acquiringall the informationnecessary for the efficientmanagement of secondaryequipment in a powernetwork. In order toguarantee efficientutilisation, informationmust be weil structured,and powerful and consis-tent tools must beavailable for handling il.In a broader perspective,Substation Monitoringsolutions contribute tomore cost-effectiveutilisation and higheravailability of primaryequipment.

The four corner stones ofSubstation Monitoring

Different personnelcategoriesapply diffe-rent system equirements.SMS is mainlyintended for personnelcategoriessuch asprotection engineerswho require detailed n-formation like protection settings anddisturbance recordings.However, SMS isalso aimed at other, more operator-orientedinformation, e.g. measured aluesand faultlocator information, since such nformationis easilyaccessiblen the system.The mainpurpose of a systemsuch as SMS is not justto acquire nformation, hut also o present tin a structured and user-friendly war.

All protective relay ettings ina network can be stored in the SMsttucture and serveas he overall s ttingdatabasewithin the utility.

Tools are also available for c culationofsetting values.These tools simpl fy thefine-tuning of settings in order to nsure thefastestpossiblefault clearing for types offallits.

Terminal setting and supervisionOwing to the immense functionality andflexibility of today's protection terminals,SMS can offer a wide range of setting andconfiguration tooIs. These can be used bothon~line and off-line, mus making possible

SMS considerablysimplifies the setting andconfiguration of theterminals. Furthermore,system overview andunderstanding of thefunction is enhanced. Theconsistency of the userinterface is guaranteed ina whole range of differentworking environments.

Event reportingDifferent types of event reporting arerequired depending on the task at hand. Themost detailed information is stored in theterminals andit registersall the eventsduring a fault. On a higher level, only themost important events,specified by the user,will be shown in order not to create nfor-mation pollution. In this war, eventreporting can be used for both. fast decisionsdirectly arter a fallit, especiallywhenpresentedas an alarm, as weIl as subsequentdetailed analysis.

To save time whenevaluating a disturbance,the expert analysis pro-gram can be used. Whenevaluating a fault, thedistance to the fault is alsocalculated. All informationis stored in a database at acentrallocation. Extensivestatistic functions can beused when evaluating theinformation in differentways.

Events at different levelscan be accessed for bothfast operator informationand detailed evaluation. Allevents originate from asingle source, i.e. theterminals, in order toguarantee consistencythroughout the system.

SMS is part of the PYRAMID@ concept forSubstation Automation and the Panoramaconcept for Power NetWork Management.Panorama ncludes intelligent terminals inthe intelligent substation for the intelligentpower network, from generation oconsumption.Substation Monitoring can either be builtup as a separate ystem, or be p-artof atotally automated substation ncluding acontroI system.The three keywords for thesystemconfiguration are:

Overall system economy is to a largeextent a function of simple and efficientengineering and maintenance of the sys-tem structure, and it is normally under-take~ by the user. The installation andutilisation of the various programs callfor high-quality documentation as weilas professionai support.

FlexibilitySystemconfiguration flexibility is achievedthrough different ways of communicatingwith the terminals. The SMS PC can com-municate with the terminals in severalways.
