ETAP combines extensive modeling capabilities with advanced solution algorithms enabling you to undertake a wide range of studies required for grid connection and grid impact analysis of wind parks, PV generation, and other renewable energy power plants. Recurring tasks can easily be automated using etapPY™ scripting tools to streamline the analysis. ETAP Grid Code Compliance is an analysis module designed to evaluate compliance with utility grid code requirements. The application includes automated harmonic analysis for detailed power quality assessment report demonstrating that the generation facility is designed to comply with the applicable harmonic limits. Recognizing that there are increasing numbers of non-linear loads looking to be connected, grid code regulations governing their connection have been evolving throughout the world. Network owners have adopted industry standards such as IEEE 519, IEC 61000 series, etc., and developed specialized application guides such as ENA Engineering Recommendation G5/5 for harmonic voltage distortion planning and compatibility levels.
