2.6極三相同步發電機之每相輸出瞬時電壓

e=359.2sin(377t)，供應某6極，轉差率S=3%，效率eff=90%，輸出為15.087Kw的三相感應馬達。此時的瞬時電流i=25.4√2sin(377t-30°) 。試求

註：e = E_MSin θ = \(\sqrt{2}\)ESin ωt = \(\sqrt{2}\)ESin2 π ft i = I_MSin θ = \(\sqrt{2}\)I sin ωt = \(\sqrt{2}\)ISin2π ft

發電機之輸出功率\(P = 3E_p I_p \cos \theta \) cos θ為功率因素，且\(\theta = 377t - (377t - 30^\circ) = 30^\circ\)

(4) 發電機輸出功率 \((P) = ?\)
