Research on Integrating Wind Turbine into Intelligent IEC 61850 Substation Automation

With the increasing demand for electricity as well as the rise of renewable energy resources connecting to the power grid, the bidirectional fault current contributed by renewable energy increases the complexity of power system and impacts to the grid stability when connected. Smart grid concepts have been applied to the power systems to tackle those issues aforementioned. Smart grid is a system which relies importantly on automation in substations using IEDs with the IEC 61850 standard. In this paper, IEDs information models were defined and configured for test based on substation protection strategy and control logic. As mentioned earlier, renewable energy resources are critical and important in Smart Grid, therefore, this paper explicitly explained how several multi-vender wind turbines were integrated by the Gateway that converted the wind turbines information from OPC to IEC 61400-25 information models. An IEC 61850 based SCADA system was developed.
