PSS Studies

Test 1c and 3 – Post-disturbance loading and voltage limits with combined SHEP (90MW)  Peak and trough case ▪ Category B (N – 1) and C (N – 2 and double) contingencies scan in steady state Cat B observations: • No thermal overloads due to combined SHEP • Peak case – thermal overloads observed but violations (around the KTBR275 and PMJY275) not due to combined SHEP • Trough case no thermal overloads • Voltage band and range violations observed but these are not due to combined SHEP Cat C observations: • No thermal overloading observed on lines connected to PMU two buses away from the PCC (both peak and trough) • There are multiple thermal and voltage violations for N-2 of parallel lines in other parts of the network; but these are not due to the combined SHEP ▪ Combined SHEP (90 MW) Comply to the pre-disturbance loading and voltage limits under normal operation ▪ ▪
