A 50 Hz synchronous generator is connected to an infinite bus through a line. The p.u. reactances of generator and the line are j0.3 p.u. and j0.2 p.u. respectively. The generator no load voltage is 1.1 p.u. and that of infinite bus is 1.0 p.u. The inertia constant of the generator is 4 MW-sec/MVA. Determine the frequency of natural oscillations if the generator is loaded to 60% of its maximum power transfer capacity and small perturbation in power is given. 1.32 Hz 1.52 Hz 1.62 Hz 1.42 Hz TRUE ANSWER : ? YOUR ANSWER : ?
Which one of the following statement with respect to Aerial Bunched Cables (ABC) system is TRUE? ABC system requires more clearance, insulators and high maintenance. ABC system is not suitable for rural electrification which are situated in difficult terrain, hills, forests and coastal areas. The overall cost of the ABC system is very high as compared to the bare conductor system. ABC system totally eliminates the fault on lines and thereby improving the quality of supply. TRUE ANSWER : ? YOUR ANSWER : ?
