Please solve the question given below of power systemsprotection
Apply three stepped distance protection philosophy of long transmission line (shown in figure below) to solve the numerical problem whose data is given as: Sr. No. 1 2 3 4 5 6 7 8 9 10 11 12 13 Operating time T₂ T₂ Parameters Line Length (T₁=T₂=T3) Voltage (L-L) Frequency A Line Resistance (R₁=R₂) Line Resistance (Ro) Inductive Reactance (X₁) Capacitive Reactance (Xc) Inductive Reactance (XL) Capacitive Reactance (Xco) Positive Seq. Impedance (Z₁) Negative Seq. Impedance (Z) Power Angle Fault Type Hint: Use book design scheme preferably. You can use internet or any power system software. You can assume any missing parameter. Instantaneous Line under consideration N- Value 100km 230kV 50Hz 8 0.035792/km 0.363 Ω/km 0.578 Ω/km 305.8M 92-m 1.323 92/km 430.6M 92-m 50.905 Ω 137.18 Ω 20 degrees L-G Adjoining line (next line) Z₂ (0.8 to 0.9)ZAB ZAB+ 0.5Zac C Z3 ZAB+ 1.2 Zac
