Figure 3.39 shows a oneline diagram of a system in which the three-phase generator is rated 300 MVA, 20 kV with a subtransient reactance of 0.2 per unit and with its neutral grounded through a 0.4- reactor. The transmission line is 64km long with a cries reactance of 0.5-/km. The three-phase transformer T1 is rated 350MVA.230/20kV with a leakage reactance of 0.1 per unit. Transformer T2 is composed of three single-phase transformers, each rated 100 MVA, 127/13.2kV with a leakage reactance of 0.1 per unit. Two 13.2kV motors M1 and M2 with a subtransient reactance of 0.2 per unit for each motor represent the load. M1 has a rated input of 200 MVA with its neutral grounded through a 0.4- current-limiting reactor, M2 has a rated input of 100 MVA with its neutral not connected to ground. Neglect phase shifts associated with the transformers. Choose the generator rating as base in the generator circuit and draw the positive-sequence reactance diagram showing all reactances in per unit.

Consider 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.

The Electricity Company of Ghana (ECG) has set up a system for reporting power supply faults in the Greater Kumasi Area, including high or low voltage and frequent power outages. Customers can contact ECG customer service and report their issue, providing their ECG pole reference number. The faults are recorded and sent to the ECG Fault Office for action. However, there is a delay in resolving the faults, and clients have to make several follow-up calls to check on the status of their complaints. The ECG management team conducted a survey and found out that customers want their faults resolved within three hours, and any delay beyond that is unacceptable. The team is looking for a solution that will offer a seamless experience to customers and minimize time and effort wasted. a) Given the information above, and making reasonable assumptions, model the current (‘AS IS’) and explain business processes at ECG Fault Office.…
