The paper begins with an introduction that describes the concept and
importance of power system security. The mathematical model is built
depending on both the linear load flow technique and the sensitivity
factors for line and generation outages.
The algorithm has been designed
so that a power system of arbitrary bus number and voltage levels can be
studied. This algorithm has been programmed in Borland Pascal in
interactive mode, and the developed program has been tested on several
test systems. The Program has been used for security assessment of a part
of the Syrian 230 kV network. The obtained results have shown the
validity and effectiveness of the program in spite of using linear models.
It is worth saying that the developed program is the first one for security
assessment in Syria so far.
