Consider a system with the single line diagram shown in Fig. 3. The three phase transformer name plate ratings are listed. The transformer reactances are given in percent; 10% = 0.1 p.u. The transmission line impedance Zz is 10+ j100 ohms and load impedance Zload is 440 ohms. The generator has a terminal voltage (magnitude) of 13.2 kV (line-line). Find the power delivered to the load, the power supplied by the generator and the efficiency. [Suggestions: In your calculation, use the 3-phase complex power base value of 10 MVA for the entire system and a base line-to-line voltage value of 138 kV for the transmission section. What about the phase-shift induced by the two transformers?] 1 13.2 kV K 38 5MVA 13.2 A-132 Y KV X₁,-10% 1₂ Z₁-10+j100 Fig. 3 M E 10MVA 138 Y - 69 A KV X₁₂=8% 12 Zload Consider a system with the single line diagram shown in Fig. 3.
