SA ( SUBSTATION AUTOMATION ) PREPARED BY GOPALA KRISHNA PALEPU ADE/MRT(PROTECTION)

ADVANTAGES OF SA More Effective Long Term Planning & Loading Decisions PLANNING

Real-time Analysis that Avoids Interruptions ENGINEERING

Reduction in the Need for Costly Field Visits PROTECTION

Precise and Confident Operator Decisions in Restoring Service MAINTENANCE

ADVANTAGES OF SUBSTATION AUTOMATION 1. LOCAL & REMOTE GRAPHICAL VISUALISATION OF ELECTRICAL DIAGRAMS OF BAY & SYSTEM VIEWS. 2. ALARM PAGES & SOE ARE DISPLAYED AND PRINTABLE. 3. TREND WINDOWS: SEVERAL CURVES CAN BE FULLY CUSTOMISED BY THE OPERATOR. 4. CONTROL WITH THE “SELECT-BEFORE OPERATE” SECURITY COMMANDS. 5. SAVING OF HISTORICAL FILES. 6. SYSTEM CONFIGUARATION SCREEN. 7. TIME SYNCHRONISATION 8. MONITORING OF CIRCUIT BREAKER. 9. MONITORING OF TRANSFORMER. 10. MONITORING OF CTs, PTs, & CVTs. 11. MONITORING OF RELAYS, ENERGY METERS & PANEL METERS. 12. CONFIGUARATION OF RELAYS 13. DISTURBANCE RECORD VIEW.
