abstract = {In the IEC 61850 standard, the transmission of the sampled values packets of measurement in processing communication are defined, and these parameters are really important and critical in the automation of power systems. Related to the security analysis of the communication networks, a really powerful tool is the Stochastic Colored Petri Net (SCPN), because it models asynchronous and concurrent processes, and it is useful to analyze delays in timed systems. So, based in this context and knowing that the correct value of sampled values measurements is really critical in transmitting messages in the IEC 61850 context; it is modeled in an IEC 61850 scenario a cyber-attack using SCPN that aims to modify the data to be transmitted before it is packed as a Sampled Value (SV) message, what is really critical for the operation of the system. The results corresponded to the modeled cyber-attack, showing the efficacy of the proposed modeling method.},
