- Consider the oneline diagram of a simple power system shown in Figure 9.20. System data in per-unit on a 100-MVA base are given as follows: The neutral of each generator is grounded through a current-limiting reactor of 0.08333 per unit on a 100-MVA base. All transformer neutrals are solidly grounded. The generators are operating no-load at their rated voltages and rated frequency with their ENIFs in phase. Determine the fault current for a balanced three-phase fault at bus 3 through a fault impedance ZF=0.1 per unit on a 100-MVA base. Neglect -Y phase shifts.arrow_forwardAt the general three-phase bus shown in Figure 9.7(a) of the text, consider a simultaneous single line-to-ground fault on phase a and line-to-line fault between phases b and c, with no fault impedances.

Determine the per-unit fault current if the fault is line-to-line-to-ground. j10 j12 j14 j16arrow_forwardDescribe the importance of load balancing in maintaining a stable power grid.arrow_forwardConsider the occurrence of single line-ground fault at the neutral end of a Y connected primary winding of a transformer where the neutral is grounded through an impedance. Now, you prescribe an efficient primary protection scheme with appropriate diagram that will take care of the situation. Also, justify (with diagram) that your prescribed protection scheme will be able to detect the ground fault successfully.arrow_forward
