1. What is the torque angle d of this generator at rated conditions?
2. Assume that the generator field current is adjusted to supply 480 V under rated conditions. What is the static stability limit of this generator? (Note: You may ignore RA to make this calculation easier.) How close is the full-load condition of this generator to the static stability limit?The full-load rated power of this generator is less than half of the static stability limit.
3. Assume that the generator field current is adjusted to supply 480 V under rated conditions. Plot the power supplied by the generator as a function of the torque angle d. (Note: You may ignore calculation easier.)
