Unformatted text preview: a) What are its synchronous reactance and armature resistance in ohms? b) What is the magnitude of the internal generated voltage E A at the rated conditions? What is its torque angle at these conditions? c) Ignoring losses in this generator, what torque must be applied to its shaft by the prime mover at full load? Problem 3) In the two bus network below, the line impedance is (0.01+j0.1)pu and the load S = (56+j13)MVA. Calculate two iterations of the Newton-Raphson AC power flow. Clearly write the formulas for the admittance matrix and the Jacobians for this network. Use 100MVA as the system power base. Problem 4) For the four bus system below, line Z is given in pu, power in MW/MVar (S base =100MVA). a) Calculate the distribution factors matrix. b) Bus angles and real power flows using the distribution matrix from part a. In both parts a) and b), clearly label bus numbers and lines used in the matrices....
