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
