In this paper a real time simulator of distributed control system (DCS) is developed according to IEC 61860 standard. IEC 61850 is the most important standard used in Smart Grid. In the first part, different parts of the control system is modeled and simulated according to IEC 61850 standard. For the modeling and simulation of communication network protocols which are based on the mentioned standard (GOOSE and INDUSTRIAL ETHERNET), OMNeT++ simulation platform is applied. HMI pages of the simulator which are completely in line with the main control system, has been developed using .NET framework. The developed simulator may be used in evaluating IEC 61860 standard and in educating operators of high voltage substations. Additionally primary equipment such as transformers, breakers, disconnectors and the secondary equipment such as distance relays and differential relays has been also modeled andsimulated in MATLAB/Simulink
