**7. Conclusion**

This chapter discusses the development of an educational simulator for the FACTS devices. The motivation of this first version of simulator is to provide the undergraduate engineers students with a simple and flexible tool about the principle of FACTS modelling and the contribution of FACTS devices to enhance power quality. The simulator has been developed under the simple graphic user interface (GUI) from MATLAB program. In this first version the user can edit, modify and save the FACTS parameters proposed for each type of Controllers in a specified file (Data) and choose location of different FACTS based on the results given by power flow and his personnel practical experience.

Power quality analysis based series FACTS devices (TCSC Model), and Hybrid devices (UPFC Model) can be demostrated using the same strategy, due to the limited chapter length, new results related to these devices will be given in details with the next new chapter.
