Operation centers around the world have verified an increase of the complexity throughout the years, mostly due to huge amounts of new information that must be considered. The Brazilian electric system is no different, impacted by the increasingly active participation of renewable sources, such as wind and photovoltaic, as well as direct current links. Following a global trend, the consideration of values of synchronous inertia for the evaluation of the performance of the frequency is necessary, configuring as a new information to be exposed to real-time operation. With the purpose of guaranteeing more safety and reliability to the real-time environment, this work has the goal of translating the studies carried out by the ONS planning team to the operation, through a system capable of monitoring parameters such as synchronous inertia, operating reserve and other associated informations, increasing users situational awareness. Besides that, the system must promote simulations of severe contingencies that may trigger load shedding schemes and indicate actions that can be taken to soften the problem.
