14 INDEX 1. INTRODUCTION 2. VIRTUAL COMMISSIONING 3. MODBUS TCP 4. GOOGLE EARTH 5. NETWORK PLANNING 6. CONCLUSIONS DIgSILENT Ibérica SL. 27 CONCLUSIONS PowerFactory capabilities can be extended way beyond the normal use of the software: allows connecting to your SCADA systems and using PowerFactory to generate signals for the full scale system and/or import measurements into your simulations. DLL (digexdyn, digexfun, digdplfun) allows building DSL and DPL functions to directly communicate with devices using different protocols (Modbus, DNP3, Ethercat, etc.). API allows modifying PowerFactory objects from your external applications and sending data to external data repositories. Smart Grids planning and event analysis are typical applications where you can exploit the full potential of PowerFactory connectivity. DIgSILENT Ibérica SL
