Using linear stability analysis, show that the system is asymptotically stable. Hint: stability of a linear system z_dot = Az is characterized by the eigenvalues of A.arrow_forwardAnswer all the questions (a) How much power is the wind farm generating? (b) How much power is the solar farm generating? (c) Find the power delivered to the AC motor. (d) If the AC motor requires at least 45 kW of power, is the system able to provide that power? If not, how many additional series PV modules should be added to each string (we want to keep the same number of modules in each string)? If so, how many modules can be removed from each string while still meeting the requirements?arrow_forward

H(1) = 35.7 kj/kmol H(2) =32.0 Kj/kmol H(3)= -1.26 Kj/kmolarrow_forwardAn open-circuit voltage of 240 V appears across the slip-rings of a wound-rotor in- duction motor when the rotor is locked. The stator has 6 poles and is excited by a 60 Hz source. If the rotor is driven by a variable-speed dc motor, calculate the open-circuit voltage and frequency across the slip-rings if the dc motor turns a. At 600 r/min, in the same direction as the rotating field b. At 900 r/min, in the same direction as the rotating field c. At 3600 r/min, opposite to the rotating fieldarrow_forwardIf we double the number of poles on the stator of an induction motor, will its syn- chronous speed also double? The rotor of an induction should never be locked while full voltage is being applied to the stator. Explain. Why does the rotor of an induction motor turn slower than the revolving field?arrow_forward

What is the nominal speed if the slip at full-load is 6 percent?arrow_forwardA 3-phase, 75 hp, 440 V induction motor has a full-load efficiency of 91 percent and a power factor of 83 percent. Calculate the nominal current per phase.arrow_forwardPlease answer all the questions a) What is the minimum required transformer rating for each transformer in kVA? b) Find the voltage required at Bus 1. c) The loadcentre is to be powered by PV panels that have the same I-V curve (ISC = 120 A, VOC = 60 V). Identify the configuration that uses the minimum number of panels to provide enough power to Bus 1. You can assume that the inverter converts the power at 95% efficiency and requires V DC input to generate the same VRMS AC output.arrow_forward

Give two advantages of a wound-rotor mo- tor over a squirrel-cage motor. Both the voltage and frequency induced in the rotor of an induction motor decrease as the rotor speeds up.
