(141) SCADA System ’s Substation Automation System provides a complete supervisory control solution for substations (HV, MV, MCC, LC, etc.). It is also a Distributor Control System (DCS). The system uses the industry’s latest technology.. Main Functions of SCADA System Supervisory Control To control the system elements like CBs, Isolators and Voltage Regulators. Remote control is available either manually, by selecting icons, or automatically via event or time schedules. Master Control is delivered with a full sequence language capability that can provide wide area control. Third party applications can also initiate controls via APIs (Applications programming Interface).. Data scanning ` #

Alarms The ability to alarm when unsolicited event happened and the ability to manage the alarms, including links to secondary and primary alarms so that a power failure will not swamp the Operations Centre with unnecessary alarms. Alarms are user-prioritized and automatically routed to the relevant users and workstations. These alarms can be routed to radio pagers, sent by SMS message to cellular phones, or e-mailed to relevant users.. 3.

(147) Historic data Save all data in historical database. The database is very useful for studying the system condition and reporting..
