PSS®SINCAL releases

What’s new in PSS®SINCAL?

Power System Analysis in Multiple Monitors Mode

For the extended simulative analysis of complex power systems users typically apply various tools in PSS®SINCAL as the main or substation views in the network graphic, but also the result, tabular and diagram views. With PSS®SINCAL 18.0, users can leverage multiple monitor environments by decoupling the tabs from the main window and arranging these on the available screens. By that, an extensive analysis system evolves, which synchronizes all input data, results, and evaluations for a common data basis on all available monitors.

New Module: Thermal Destruction Analysis (TDA)

The operating equipment of the network must be designed to withstand short circuits. Until now, this required extensive manual short-circuit calculations for the entire network area, considering the clearing times of the network protection.

 

The new module Thermal Destruction Analysis enables both the network planning and the protection department to perform an automated check for thermal destruction for all lines and transformers in the network.

 

As a result, the user receives a clear representation of all the equipment with simulation results showing thermal destruction. A detailed analysis in the network is directly accessible from the results view. Based on the results, measures regarding network protection or network expansion can be derived and their effectiveness can be checked by the thermal destruction analysis.   

Supporting COMTRADE Data Format in Export and Import

The COMTRADE data format, which is defined in IEC Standard 60255-24, enables users to exchange information of instantaneous values for analysis of transients after faults or other events. On the one hand, this data can be used to validate network models and to compare with simulation (EMT). On the other hand, the combination of simulation (EMT) and digital analog amplifiers provides testing capabilities of for instance protection devices and their algorithms. To cover these use cases, PSS®SINCAL 18.0 delivers a completely revised COMTRADE export function for several standard versions as well as the possibility to import COMTRADE data from recorders. With the Signal Explorer, these can visualize and evaluated in PSS®SINCAL.

New result configuration approach for tailored internal, external or signal result creation

The simulation of large networks in many scenario cases, operating point, snapshots or over time periods may create extensive amounts of results for later analysis. The new configuration approach for result storage in the network database (internal), open result databases (external) or signal databases (for the usage in the diagram view) enables a flexible and tailored result storage process and management depending on the desired use case. This enables both granular and highly detailed studies as well as automatic post-processed aggregated network level or area result sets. Simulation times are reduced, results are provided in user-defined scope depending on the use case and results are available as an open accessible source for external big data analysis tools and dashboards.

New example networks with focus on protection and industry

Five new example networks (Example OC, Prot, PSA, Industry and TDA) are delivered with PSS®SINCAL 18.0. Based on the example networks, users can get an introduction to the functions for network protection, starting with the modeling, the setting of the protection devices, the simulation, and the evaluation of the results. In addition, typical protection concepts for different protection functions such as overcurrent protection, distance protection, differential protection and signal comparison are stored in the application examples. This enables the user to quickly familiarize themselves with the way network protection is modeled in PSS®SINCAL. An example regarding the protection analysis function shows how the viability of the entire network protection can be checked fully automatically, considering various conditions. The example networks for users at industries as plants or refineries get a descriptive presentation of the analysis capabilities in PSS®SINCAL. It focuses on investigations of steady-state and dynamic phenomena such as disconnection from the grid after faults, load shedding in island operation, motor start and dynamic voltage profile.

 

Another example network for thermal destruction analysis introduces this new module. The different modes, which are tailored to network planning and the protection department, are explained and it is shown how the thermal short-circuit current capability of the equipment can be tested fully automatically.

New Model Samples for Multi-Terminal HVDC Systems and Automatic Generation Control (AGC)

The representation of the enormous complexity of future energy systems gains growing importance. These systems contain beside couplings of sectors as well as of AC and DC networks also hierarchical control structures for new and conventional equipment, which can be extensively modeled in PSS®SINCAL. The new model examples serve as implementation proposals as starting point for user-defined modeling of such complex systems in the frequency range of power system dynamics for stability analyses.

Official Support of Windows 11

In October 2021 Microsoft officially released the new operating system Windows 11 as successor of Windows 10. Therefore, PSS®SINCAL Platform 18.0 has been extensively tested during the development phase in the new environment. It supports the new operating system Windows 11 completely, and you are well prepared for the future requirements of your IT landscape. Operating systems for Windows 8 & 10 are still supported.

Scenario Support for Protection Settings

Bidirectional power flows, caused by renewable energy resources and different operation status, can require changing protection settings. Therefore, a fast and flexible adjustment of the parameter set is needed.

 

The network data file (.xml file) now supports the complete protection settings to be imported and exported. This is in order to manage several parameter sets of the same protection device (can be used in variants and scenarios) or transfer settings from one device to another. This function can also be used to create type parameter sets for recurring protection settings.

Dynamic Voltage Support

The increase in short circuit contribution of converter-based generation requires a simulation model that reflects a voltage dependent reactive current injection for short circuit calculation and protection analysis. For example, such an action is required by VDE-AR-N 4110 and Engineering Recommendation G74 Issue 2.

 

The dynamic voltage support function allows engineers to simulate the short circuit contribution of the converter by a reactive current injection dependent on the voltage drop at the connection point. As such, the dynamic voltage support characteristic can be adjusted and the positive and the negative sequence system are supported.

New Diagram System for all Simulation Methods

The new diagram system in PSS®SINCAL is characterized by additional functions, higher flexibility and performance, as well as lower storage requirements. This system is now applied on all simulation methods and replaces the previous approach. All relevant input data, results or external source data can be represented graphically by manual creation from Signal Explorer or, for specific calculation methods (in protection, harmonics, motor start etc.), automatically by assistants employing pre-defined templates. This saves users time and effort and enable a more efficient way of handling the network model. By utilizing the built-in evaluation functions and a higher accessibility of data in open databases, users gain additional value in the analysis part of their network planning process.

Time Series Data Interface (TSDI)

The new Time Series Data Interface (TSDI) offers an interface to an open generic time series database. This facilitates the cooperation between operation, metering and planning teams by integrating time series data (like measurements, forecasts or schedules and switching events) into the initial condition for all power flow based analyses or into a complete time series simulation. This leverages the investment in metering, SCADA and forecast systems for grid analysis and planning use cases. 

“simbench” Network Model Repository & pandapower Import

Demonstration, prototyping, testing, research and development require benchmark network models. The simbench repository provides high, medium and low voltage networks for PSS®SINCAL based on the simbench data set publicly available. In addition, a pandapower model to PSS®SINCAL model converter (py-library) is available on request.

Representation of input values and results in per unit [pu]

The visualization of input data and results in per unit [pu] is now possible in network graphic, data masks and tabular view as network model specific option.

 

In addition to the handling of network models with the absolute values for impedance [Ω] of input data, or results, the representation can now be done in per unit [pu] based on each assigned network voltage level and the common reference power.

Strengthening Modeling Capabilities in Graphical Model Editor (GMB) 
Modeling autonomous and coordinated operation of power systems in steady-state and dynamic simulation is crucial for future network planning and operation. PSS®SINCAL provides the possibility to implement different concepts of modern operation by simplified central and decentral model communication. New functions, blocks and a completely revised functional documentation support users in creating user-defined models in GMB.

 Improvement in Handling of Line Couplings and Extensions for Disconnected Lines

If parallel coupled lines are disconnected by events or for maintenance purposes and are optionally earthed at the terminals, it may have an impact on operation and protection of the active line. Furthermore, induced currents and voltages occur in the switched-off lines, which have to be observed. By considering couplings (defined by zero phase coupling or coupling data) as well as using the new earthing disconnector PSS®SINCAL provides new network modeling options for isolation and protection coordination.

 

 

Protection Analysis - Pickup Security (PSA)

The operating currents occurring in the network must not lead to the pickup of the protection systems, the protection devices must therefore be able to differentiate reliably between load and short-circuit current. By checking the pickup security in the protection analysis, it can be ensured that operating currents that occur, taking into account a security factor, certainly do not lead to the pickup of the protection devices.

 

Improved Excel import
With the Excel import functionality in PSS®SINCAL , you can import network or protection data into PSS®SINCAL. The Excel import dialog has been improved and adapted to the users workflow.

 

Extension of the Multi-User Master Database (PM) 
When working with multiple users or teams on complex network models, certain requirements must be fulfilled in order to manage a common network model to track the changes of individual users and keep the network model consistent. In the current version, the Multi-User Master Database is extended so that the administration can be opened directly without loading the network data and graphics, client users are automatically informed about updates in the Master Database when they open their network, and users can change their password without the intervention of the administrator. In addition, the administrator is supported in managing the master network in such a way that changes in the publications of the users are highlighted in the preview of the network graphic. These enhancements lead to a significantly increased efficiency in sharing a common network model. 

*New module* Network Stress Test 
Stochastic simulation and interactive visualization of the impacts of rising EVs or DERs on your system.
 
With the increasing development of electromobility, electric vehicles (EVs) will start to have a large impact on the distribution grid. The grid will become more unpredictable as the connection points and magnitude of the e-car charging stations or DER are unknown, and the network load varies by time and location. Standard load flow studies will no longer be enough to ensure reliability. Distribution utilities will need to leverage state-of-the-art technologies in order to prepare their grids for the future.

With the new PSS®SINCAL Network Stress Test module, distribution grid planners can easily simulate the current and future impacts of e-mobility or DER on their networks. This means that utilities can now understand how their networks will be affected over-time by the increasing penetration of EV charging stations or DER and identify future requirements for network enhancements. Through this stochastic approach, grid planners can save time through no longer needing to rely on trial and error approaches with hundreds of what if scenarios.

 

Seamlessly link and manage external network equipment documents 
Easily manage all your documents related to network equipment such as transformers or protection devices. This new feature enables you to link external documents, such as PDF files or Word documents, to network elements, store/manage the links, and view the most up-to-date linked document directly within the PSS®SINCAL GUI. 

Efficiently build user specific solutions with the new Python™ automation documentation
Python™ is an increasingly important language for user-defined programs. With the new documentation of PSS®SINCAL COM-Server architecture, users can speed up the usage of this programming language to automate user interface access, GUI development, calculation automation, and data management. Save scripting time by leveraging copy and paste program snippets, and ready to use examples for programmed features.

Highly detailed load modelling and split trimming from Feeder 
Utilize forecast data that in general is split between load and generation PSS®SINCAL meter devices which were already handling real-time and historian data can now trim two different elements groups with profiles in parallel. In addition, users can select between various scaling or trimming algorithms to quickly adjust loads and distributed generation during long term (e.g. year) evaluation to speed up the simulation time. 

Simulate user-defined contingencies and Remedial Action Schemes by scenarios 
Utilize the already existing scenarios which can contain any kind of network changes for Contingency Analysis. Easily set-up, simulate, and evaluate user-defined contingencies and Remedial Action Schemes (RAS) which support your daily operation planning actions or reflect your company-specific planning criteria. 

Innovative evaluation and documentation of thermal damages and new backup protection schemas in the Protection Security Assessment 
With the new matrix overview, you can quickly get an overview about the reliability of the networks concerning the thermal damage of elements caused by short circuits. Define protection backup strategies or have user-defined backup protection devices for each protection location.

Support unbalanced networks also in Feeder Evaluation 
Automatically detect, build, evaluate, and highlight the feeders within your unbalanced distribution network. This new feature enables you to quickly evaluate the network configuration, get an overview of the key parameters of large networks, and review reconfiguration/restoration options in case of feeder outages. 

Extended modeling of dynamic network elements
With the increase of DERs in the distribution grids, planners need to consider the resulting impacts on the analyses of steady-state and dynamic power system behavior. This is possible with the new concept of Multiple Input Multiple Output (MIMO) models which enable users to model modern and future system concepts. Users can adequately model DERs representing each phase individually to provide a more realistic view. 

New elements to support the Russian Market 
Users can now model completely new (3-node connected) elements including dual reactor and split winding transformers based on name plate values and without the need to recalculate input data. This element modelling also supports the already existing GOST Standard in a more detailed way.

Achieve network layout compliance with Short Circuit and Arc Flash 
PSS®SINCAL v15.5 supports you to achieve network layout compliance when working with standards for Arc Flash Hazard and Short Circuit Analysis. The new version will support - in addition to the already supported standards - the new standards IEEE1584 2018 (with NFPA 70E), IEEE C37 2016, and IEEE C37 initial load. 

 

Improved functionality and efficiency of Harmonic Analysis
Run detailed harmonic analysis with the new automated contingency simulation capabilities. This enables you to get a better understanding of harmonic distortions with all elements in service and during contingency situations. Automatically create resonance networks.

 

*NEW Module* Efficiently automate sizing and placement of Energy Storage
With the Energy Storage Sizing and Positioning Module, simplify simulation of Non-Wired Alternatives (NWA) to mitigate reliability concerns within your volatile network. By using a simple workflow support wizard, this new feature will automatically generate the required location and size of energy storage. No longer rely on a time-consuming trial and error approach when modeling batteries.

 

Reduce simulation time and increase focus of Hosting Capacity Analysis
With just one simulation, you can now quickly determine the maximum DG capacity for multiple or single nodes at once. This module was further enhanced with the ability to automatically determine critical operating points – allowing you focus on time periods that matter. 

 

Utilize enhancements to the Protection Security Assessment (PSA) module
Utilities need to run many simulations when checking the accuracy of protection device settings. The PSA module enables you to check the full network with different fault types and view the results in a comprehensive graphic visualization. With v15.5, PSA now includes breaker outage, thermal destruction time with switching sequence consideration, and  pickup safety margins.

Experience higher model flexibility and validity for Torsional Analysis 

Utilizing the expert mode of the dynamic engine of PSS®SINCAL platform (PSS®NETOMAC) users have new possibilities in handling of various generator masses on drive shafts.  With the enhanced capabilities of air-gap torque distribution as well as park transformation control, users immediately achieve value by experiencing a higher degree of flexibility in modeling and inturn achieving higher grid utilization. 

 

New user-defined models for GMB to quickly create subsystems and reuse control functions

Graphical Model Builder (GMB) is our graphical modeling tool for the entire  PSS® Portfolio with the focus on user-defined models. Newly extended model types (FCT) now allow a way of creating subsystems and the ability to efficiently reuse of control functions. This also includes enhancements to the linking and set-up options of DLLs. In addition, several minor improvements have been made to this tool to create a better user experience.
