DIgSILENT StationWare provides a reliable central protection settings database and management system for the complete power system substation data, both to manage the various control parameters and to centrally store substation related information. StationWare is based on the latest .NET technology.
StationWare stores and records all settings in a central database, allows modelling of all relevant workflow sequences, provides quick access to relay manuals, interfaces with manufacturer-specific relay settings software, and integrates with PowerFactory software, allowing powerful and easy-to-use settings coordination studies.
Link to PowerFactory
PowerFactory’s data exchange facility allows it to access the settings stored in StationWare, such that these may be used as input for the powerful PowerFactory system simulation and protection setting tools. Settings that are calculated by using these tools may then be transferred back to StationWare.
What is the idea behind StationWare?
Modern numerical relays have a large number of settings that are determined, stored and communicated by proprietary software solutions (these may even be suitable for only a particular manufacturer or even a series or type of relay). This results in a fragmented and distributed settings “database.” DIgSILENT StationWare provides a single system that incorporates all such different device protocols, thereby providing one manageable software data storage system, based on modern IT techniques, facilitating data interfacing and exchange in a transparent and hassle free manner.
DIgSILENT has developed a new verification tool called DIgSILENT GridCode. The software has been designed in response to the need to verify whether a conventional or renewable power plant is compliant with local Grid Code interconnection requirements on basis of generating unit tests. There is a new trend towards verification of requirements at the point of interconnection of a power plant using transient stability simulations with numerical models. An increasing number of Transmission System Operators are including model validation methods to quantify the risk and uncertainty when using these simulation models in stability studies. These new methods have been included in the DIgSILENT GridCode tool.
The application can be automated and integrated into existing SCADA systems, but can also run on a workstation as an off-line verification tool. DIgSILENT GridCode has a new graphical user interface for easy navigation and generates customisable and automated reports in MS Word© format.
Among many others, DIgSILENT GridCode compliance verification functions are:
- Low Voltage Ride Through (LVRT): Verification of generator response during balanced and unbalanced voltage dips, verification of voltage support requirements during the dip and after dip clearance, supervision of power plant non-disconnection and/or supervision of active power recovery according to the user selected grid code.
- High Voltage Ride Through (HVRT): Verification of generator response during balanced and unbalanced voltage swells, verification of voltage support requirements during the swell and after swell clearance, supervision of power plant non-disconnection and/or supervision of active and reactive power recovery according to the user selected grid code.
- Model validation: LVRT or HVRT simulation results are compared against field measurements according to the user selected method to check that both data series fit well.
- Power Quality requirements: Flicker and harmonic levels can be assessed according to classical International Standards (IEC-61000-4-15, IEC-61000-4-7) or according to specific methods for renewables (IEC-61400-21, TR3).

The PFM features grid and plant monitoring, fault recording, grid characteristics analysis by offering easy access to recorded data, analysis of trends, verification of system upset responses and test results.
Unbundling of electricity supply systems and the introduction of new technologies in all areas of generation, transmission and distribution has made power system operation more complex. Supervision of generator performance according to Grid Codes and Connection Conditions, the stability supervision of large transmission networks at specific locations, verification of power quality criteria in distribution as well as the determination and analysis of key system parameters has generated the need for power system monitoring and grid supervision beyond classical fault recording and SCADA based trending systems. Under those aspects, wide area monitoring (WAM) via phase measurement units (PMU) is just one special feature out of all monitoring applications. The PowerFactory Monitor fully integrates with DIgSILENT PowerFactory software offering easy access to recorded data, analysis of trends, verification of system upset responses and test results.
