With the growth of technologies for the automation of electrical systems, it is important to create ways to maintain the supply of electrical energy even in abnormal situations, with fast and low-cost resolutions, keeping load restriction as a last resort. The Corrective Switching technique is a tool capable of controlling the power flow of meshed networks by changing the network topology. The main advantage of this control methodology is that it does not involve additional costs, since its implementation depends on maneuvers by elements already present in the network. In previous works, several techniques and methodologies were developed to reduce the computational time needed to implement the technique, envisioning its application in the operation of systems in real-time. The present work aims to develop a computer program capable of identifying overloads in branches of the system and reconfiguring the network in real-time through the Corrective Switching technique. The simulations of electrical networks in real-time will be carried out through RTS. The computer program with the techniques and methodologies used to choose the switching variant will be developed using Scilab software, which will exchange information with the simulation in real-time in RTS. To improve the performance of the technique in the simulations, linearization techniques were also used to gain computational time. Finally, analysis of the results obtained from simulating the corrective switching technique in real time is presented.
