The elements will be described electrical by For three windings transformers a third node must be given. 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).Įlements An 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. 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. Nodes A 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 components An electrical power system consists of nodes and elements. To understand the NEPLAN environment, it is essential that certain concepts used in the system are described:įig.
