The objective of the first part is to only prove the given equalities. Such equalities may be used to solve
questions 1, 2, or 3 in part III.
You have to use m-file Matlab to plot the synchronous generator capability curve and the maximum field
current circle on one figure using the numerical values of the machine under study. To do so, you have to
calculate current and internal voltage as requested (see questions 2 and 3). M-file will be used to write
the code and plot the figures.
The first three questions are similar to those treated in homework#3. You have to use numerical values
to solve the first three questions. You may use the equalities of part I.
The remaining questions are related to the simulation tests. The values of the prime move power and the
internal generated voltage calculated in the three first questions should be used in the simulator. Note
that the numerical values that are given in the simulator are false. You should replace it by the ones that
are calculated in the first three equations. Note that the prime mover power is equal to the converted
power since mechanical losses are neglected. The following figure gives you an idea on the variation of
the prime mover power and the internal generated voltage during time. The symbol “?” means that the
numerical value is not given and you have to find it by solving questions, 1, 2, and 3.
