Question

Q3. (a) A star-connected, 3-phase, 10-MVA, 6-6 kV alternator has a per phase reactance of 10%. It is protected by Merz-Price circulating-current principle which is set to operate for fault currents not less than 175 A. Calculate the value of earthing resistance to be provided in order to ensure that only 10% of the alternator winding remains unprotected. [5] Q3. (b) Explain how the Artificial Intelligence (AI) can be applied to power system protection? Discuss the advantage of AI based numerical protection. Describe the Artificial Neural Network properties and capabilities for application to power system protection. [5]

          Q3. (a) A star-connected, 3-phase, 10-MVA, 6-6 kV alternator has a per phase reactance of 10%.
It is protected by Merz-Price circulating-current principle which is set to operate for fault
