Resumen
The present project integrates the operational characteristics of FATCS controllers,
which, being part of the solution for electrical power systems, allow the reduction of
thermal, dielectric and stability limitations, optimizing energy transfer. Therefore, it is
necessary to start from a model already established, in this case the IEEE 14 bars, from
which it results, a reconfiguration obtaining as a result a system of 13 bars and a
dummy point. It is important to note that in order to demonstrate the usefulness of the
code, a system of 9 bars is analyzed, from which it is possible to demonstrate its
functionality by performing a reconfiguration obtaining a system of 10 bars and a
dummy point.
From the above, the system incorporates a three-winding transformer, because through
its tertiary winding is made the connection of FACTS controllers in parallel such as:
Static Var Compensator (SVC) and Static Compensator (STATCOM). It should be
added that their purpose is to improve the voltage profile in a given bar and thus
establish the necessary amount of reactive power to be injected or consumed by the
controller used.
The code generated in this work is applicable to any topology and gives solution to the
power flow, it is implemented in the Matlab software allowing to obtain results of
voltages and angles in the bars. In the case of the assigned bus, the derivation coupling
of the controllers mentioned above is made, allowing the calculation of the parameters
and achieving the reactive compensation of the controller. Finally, the results obtained
can be contrasted in the DigSILENT PowerFactory software
