The nominal line-to-line voltage at a bus ina three-phase ac system is 230kv(rms) when it is supplying a three-phaseinductive load of .
The per-phase ac system impedance ZSseen by the bus can be approximated to be purely inductive with .
(a) Calculate the percentage change inthe bus voltage magnitude for a 10% increase in P.
(b) Calculate the percentage change inthe bus voltage magnitude for a 10% increase in Q.
17-6 A hybrid arrangement of a TCI and a TSC isconnected at the ac bus in Problem 17-5.The TCI can draw a maximum of 50Mvarsper phase, whereas the TSC consists of four-capacitor banks ,each with aper-phase rating of 50 Mvars. Holding the ac bus voltage to its nominal valuefor a 10% increase in Q in problem 17-5b,calculate the number of capacitorbanks that should be switched in ,the delay angle at which the TCIshould operate . and the per-phase effective inductance of the TCI.
