A single-phase, 120V(rms),60Hz source supplies power to a series R-L circuit consisting of R=10 and L=40mH. (a) Determine the power factor of the circuit and state whether it is lagging or leading. (b) Determine the real and reactive power absorbed by the load. (c) Calculate the peak magnetic energy Wint stored in the inductor by using the expression Wint=L(Irms)2 and check whether the reactive power Q=Wint is satisfied. (Note: The instantaneous magnetic energy storage fluctuates between zero and the peak energy. This energy must be sent twice each cycle to the load from the source by means of reactive power flows.)

A 3 phase 200 MVA capacitor bank is to be switched off (disconnected) the grid that operates at 13.8kV (3-phase) at 60 Hz. The capacitor is connected in a WYE configuration, therefore the voltage across each phase is VLN=7.97KV. A restrike occurs at the zero crossing of the current. Determine the magnitude of voltage across the capacitor after the restrike. b. 0.05 mSec after the first restrike the arc extinguishes, which leaves a 1st charge trapped. Another restrike occurs again 3/8 of a cycle after the first restrike and is quickly extinguished. Identify the magnitude of voltage trapped across the capacitor after the а. second restrike.
A synchronous generator has been synchronized to an infinite grid of 13.8 kV and 60 Hz. The generator prime mover C/C is such that the no-load frequency is 62.5 Hz and the power slope is 1 MW/Hz. The AVR C/C (The reactive power against the terminal voltage C/C) is such that the zero reactive power voltage is 14.6 kV, while the slope is 0.4 MVAR/kV. Calculate: (a) the kVA loading of the generator and its power factor. (b) the settings of the prime mover and AVR such that the generator delivers 3 MW at 0.85 lagging power factor.
