2. Protection Scheme

Differential protection is set as a main protection which is have a duplicate protection interface channel (2Mbit/s).

Back up Distance is set for 4 zone quad characteristic for both phase and earth faultsi. Set Zone 1 Forward direction to cover 85% of the total line impedance, zone 1 will trip instantaneous but activate when both Main 1 and Main 2 protection relay fail or total communication channel fail.

ii. Set Zone 2 Forwad direction to cover 120% of the total line impedance. Delay 0.30s.

iii. Set Zone 3 Forward direction to cover 180% of the total line impedance. Delay 0.9s.

iv. Set Zone 4 Reverse direction to cover 40% of the total line impedance. Delay 1.0s.

v. Enable VT supervision blocking of distance protectionvi. Enable power swing blocking (PSB)

vii. Enable distance SOTF to trip fault upon energizing.Note: No carrier for distance protection.

Back up Directional Earth Fault is set to trip on delay 2.00s without carrier, instead of instantaneous trip with carrier received. All backup protection trip such as distance operate, DEF operate, CBF operate, OC operate and BBP operate will initiate direct intertrip send to remote end via signal protection interface Main 1 relay and Main 2 relay.

ICharg = U / (3 XC)

Where:

U is system voltage

XC is capacitive positive sequence reactance of the line

f is system frequency

C is positive sequence line capacitanceThus,

Ic = (3.63) (275kV) (50Hz) (14.8024 nF/km) (47.626 km) = 35.187 A

ii. Distance Characteristic

Characteristic for the phase-to-earth measuring loops Characteristic for the phase-to-phase measuring loopsiii. Distance Zone Setting Calculation

The zones are set directly in primary ohms R,X.

Rf/X factor: typically 2/1.5 for long lines and 4-6 for short lines but shall be set less then 8.*Set the Rf/X factor giving the Phf resistive coverage: 2*Set the Rf/X factor giving the EF resistive coverage : 2

Resistive reach for Phase fault (RFPP) is set to Rf/X factor times X1 of each respective Zone resistive reach for earth fault (RFPE) is set to Rf/X factor times (1+KN)X1 of each

respective Zone, where KN = (Z0 Z1)/3Z1iv. Phase selection with Load Enchroachment (PPHS) Setting Calculation
