The Smart Grid (SG) concept provides that, in addition to the power flow, the utilities has a two-way data flow in all sectors of the grid to consumers. Through Information and Communication Technology (ICT), it becomes possible the sensing of entire power grid, the more efficient and faster solution failures, and the teleprotection and management of the assets of utilities. To ensure this, requirements such as security, reliability and low latency are essential. Considering that there are several applications SG, to adapt a communication system between Smart Meters for each type of environment becomes complex. Moreover, the communication study of data flow SG becomes expensive in assembling real scenarios, due to the high cost of acquisition of Smart Meters. To enable SG communication studies simulated in low cost, in this work was constituted the modeling of IEEE 1815 DNP3 protocol, validated its operation through modeling of IEEE 1815 / 802.15.4 and IEEE 1815 / 802.11b integrations. The validation and analysis were performed by modeling and simulation of both protocols in Very High Speed Integrated Circuit (VHSIC) Hardware Description Language (HDL), and performing measurements of delay in the exchange of DNP3 messages sent via integrated wireless protocols. The teleprotection latency requirements in its general context, indicate the IEEE 802.15.4 interface as inadequate for this application due to high latency scenarios in the presence of contention access, low data throughput and low resilience of improved security. Situation that does not occur for the IEEE 802.11 interface, which becomes feasible because it presents latency, data throughput and robustness safety critical application compatible with that SG
