An electric railway supply system is given in Fig. 14. The supply frequency fN =50Hz. UN = 30kV. It is supplied through a substations with the transformers' parameters as follows: U₁ = 1.1UN XT = 2.2602 XL = 6.00 R = 2.192 For the section, a traction vehicle is equipped with an AC motor. The power factor is 0.90 and the minimal voltage at the pantograph is 90% UN. Please describe how to find the maximal active power P and give the value. Uo Хт XL R Figure 14 M
