The generator in Practice A is delivering 40MW at a terminal voltage of 30kV (line-line). The excitation voltage is decreased to 79.2% of the value found in the previous example. 1) Determine the power angle, armature current, and power factor for the 79.2% of excitation. 2) Find the minimum excitation below which the generator will lose synchronism. The excitation voltage is 23.54\angle 17.10^\circ V

Consider the following single exponential smoothing model: $S_t = aX_t + (1 - a)S_{t-1}$ You are given the following data: $\hat{a} = 0.1$, $X_t = 0.5$, $S_{t-1} = 0.2$ If we believe that the true DGP can be approximated by the exponential smoothing model, what would be an appropriate 2-step-ahead forecast for X? (i.e., a forecast of $X_{t+2}$ made at time t) 0.2 0.23 0.5 There is insufficient information given in the question to form more than a one-step- ahead forecast
