An element is described topological by a starting and an ending node. There are active elements and passive elements. cable, transformer or electrical machine. Every voltage is given as a line-to-line voltage (delta voltage).ĮlementsAn element corresponds to a network component, like e.g. In NEPLAN the nominal system voltage of the nodes must beĮntered during the node data input. The nominal system voltage Un is the line-to-line voltage, for which a power system is designated and on which several characteristics of the power system has been referred. A node is described by its name (identification with 17 characters), nominal system voltage in kV, description (31 characters), network group or area, type of node (main bus bar, bus bar, sleeve, special node), association with a station. NodesA node is the connection point of two elements or a location, where electrical energy will be produced or consumed (generator, load). 2.1 One line diagram with network componentsĪn electrical power system consists of nodes and elements.

Following the formal release, we will officially discontinue support of the preceding version PowerFactory 2018 and will not provide any further service packs for this former version.TutorialThe Basic Elements of NEPLANTo understand the NEPLAN environment, it is essential that certain concepts used in the system are described: We wish you continued success with DIgSILENT PowerFactory.ĭIgSILENT will actively continue to support the two previous versions PowerFactory 20. The new and improved models and functions in the PowerFactory 2021 Previewversion continue the process of enhancement and development which ensures that PowerFactoryremains the ideal tool for a wide range of network planning and operational studies, from small micro-grids to large transmission and distribution networks, including HVDC and renewable technologies.
We invite you to learn more about these functions and many other enhancements in the What’s New in PowerFactory 2021 document, available in our Download Area, or to watch the corresponding What’s New in PowerFactory 2021 video provided on our YouTube channel.
