Abstract :
This paper deals with the influence of the medium access control (MAC) protocol in the performance of the communication channels used in power system SCADA systems (supervisory control and data acquisition). Three types of MAC protocols are presented and analyzed: polling, CSMA/CD (carrier sense multiple access with collision detection), and token bus. The simulation of each one of these protocols allows us to quantify its performance and establish certain criteria in order to be able to compare them. As a result of the analysis, the use of a MAC protocol is proposed for SCADA systems
