System simulation and results
In my paper, I choose PSCAD software as the tool for
simulations.
PSCAD is a specialized software for power system
simulation
PSCAD has a strong library with a totally graphical,
modular, hierarchical and customizable.
The equipment models also can built in C++, FORTRAN,
and MATLAB with a friendly interface in PSCAD

Conclusions
 This paper issued an important combination of equations to
solve the problem of generator planning for ship.
 Furthermore it successfully applied the method to calculate
for one tanker ship. As the results, two generators with a
rating capacity of 176kW/220kVA each that are designed for
providing load demand on this tanker.
 In addition, a power system simulation of this tanker has
been built successfully by PSCAD software with the
parameters and functions like the system in practice.
 The simulation results again confirmed that the generators
can be running well to maintain the stable and safety of power
system in any different loading conditions.
