GRID OPERATION – TYPICAL ISSUES IN PAST
• LOW / HIGH FREQUENCY PROBLEMS
– FREQUENCY EXCURSES TO LOW/HIGH VALUES
• LOW / HIGH VOLTAGE OPERATION
– CRITICALLY LOW VOLTAGES AT LOAD CENTRES
– SUBSTANTIALLY HIGH VOLTAGES AT FAR ENDS
• SYSTEM BROWNOUTS / BLACK OUTS
– SEPERATION OF SYSTEMS / LOSS OF LOAD
• ECONOMIC IN-STABILITY / INCREASED ELECTRICAL LOSSES– UNRELIABLE / INEFFICIENT OPERATION OF EQUIPMENT

REALITY BITE:
FARMERS IN KARNATAKA ARE HAPPY WITH FEWER HOURS OF QUALITY POWER!!.
EFFICIENCY OF PUMPS AT TG HALLI WATER WORKS IMPROVED!
COMPARISION OF BANGALORE VOLTAGE-TYPICAL DAY
BETTER VOLTAGE PROFILE MEANS LESS ELECTRICAL LOSSES
56
WATER SUPPLY TO BANGALORE
LOW VOLTAGE PROBLEMS AROUND BANGALORE HAMPERED WATER SUPPLY EARLIER
WITH BETTER VOLTAGE NOW, PUMPING EFFICIENCY HAS IMPROVED
400 KV STATION AT MYSORE BEING COMMISSIONED ON WAR FOOTING TO FURTHER FORTIFY THIS PART OF THE GRID
PUMPING LOSSES REDUCED
ENORMOUS SAVINGS TO THE STATE
MOTOR BURNING AND MAINTENANCE COSTS ALSO CAME DOWN DRASTICALLY
