Power Systems A generator has reactances of sub transient (X")= 0.5 pu, transient (X') = 0.8 pu and synchronous reactance (X) = 5 pu. The voltages at these reactances are 1.2 V, 1.1 V and 1 V respectively. Find the corresponding sub transient fault current in pu? 2.4 pu 0.2 pu 3.975 pu 1.375 pu 2.4 pu 0.2 pu 3.975 pu 1.375 pu ANSWER DOWNLOAD EXAMIANS APP
Power Systems A power system consists of 300 buses out of which 20 buses are generator buses, 25 buses are the ones with reactive power support buses and 15 buses are ones with fixed shunt capacitors. All the other buses are load buses. It is proposed to perform a load flow analysis for the system using Newton-Raphson Jacobian matrix is 540×540 555×555 553×553 554×554 540×540 555×555 553×553 554×554 ANSWER DOWNLOAD EXAMIANS APP
