**5. Simulation test and results using SimFACTS**

The FACTS models integrated in the proposed educational power system control are those proposed by (Achat et al., 2004), and by Canizares (Canizares, C. A, at al., ). The Newton-Raphson algorithm is used to calculate all the electrical values involved in power system.. The FACTS simulation package is capable of doing interactive simulations for several types of controllers as shown in Table 1.

Using this simplified and interactive program, user can easely understand the basic concept of this new technolgy based FACTS devices introduced to power system operation and control. During simulation user can access directly to the code source program of any desired function (Ybus, Newton-Raphson, SVC Model, STATCOM model, TCSC Model, UPFC Model, Graphic functions,) , user also can modify the content of existant models, and test the efficiency of the modiefd models.
