  This paper analyzes the impact of the integration of the Modular Static
Synchronous Series Compensator (M-SSSC) solution that will be deployed in the
Santa Marta 220 kV (Colombian substation) by using real-time simulations with
Hardware in the Loop (HIL) technique, over the protection coordination schemes
in the area of influence. The results show that the M-SSSC devices can be
successfully coordinated with the protection schemes, mitigating overloads
through the transmission lines during steady state and contingencies, while
avoiding potential harmful interactions with the grid and, most importantly,
with protection devices. This behavior is achieved by using overcurrent
detection logics implemented on M-SSSC devices that trip fast-acting Silicon
Controlled Rectifiers (SCRs) that cease the voltage injection in less than 5 ms
