The Excel import dialog has been improved and adapted to the users workflow.Įxtension of the Multi-User Master Database (PM) With the Excel import functionality in PSS®SINCAL, you can import network or protection data into PSS®SINCAL. 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. 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. Protection Analysis - Pickup Security (PSA) 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. Furthermore, induced currents and voltages occur in the switched-off lines, which have to be observed. 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.
Improvement in Handling of Line Couplings and Extensions for Disconnected Lines New functions, blocks and a completely revised functional documentation support users in creating user-defined models in GMB. PSS®SINCAL provides the possibility to implement different concepts of modern operation by simplified central and decentral model communication. Modeling autonomous and coordinated operation of power systems in steady-state and dynamic simulation is crucial for future network planning and operation. Strengthening Modeling Capabilities in Graphical Model Editor (GMB) 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. 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.Īnother example network for thermal destruction analysis introduces this new module. The example networks for users at industries as plants or refineries get a descriptive presentation of the analysis capabilities 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. This enables the user to quickly familiarize themselves with the way network protection is modeled in PSS®SINCAL. 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.
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.
Five new example networks (Example OC, Prot, PSA, Industry and TDA) are delivered with PSS®SINCAL 18.0.
