Line and Cable Parameters (LEIKA)

Requirements and Use Cases

Analytical studies of system behavior, which depend on accurate modeling of overhead lines and cables, require the corresponding input data in the form of complex equivalent circuit diagrams and frequency-dependent elements. The planning and operating process provides the user with the information in the physical characteristic values of the conductors, insulators and insulation materials, as well as the geometric arrangement. It is necessary to convert the physics into an electrical equivalent circuit diagram for the different calculation types of the PSS?SINCAL Platform.

• Determination of parameters for single- and multi-phase systems with or without ground return from the geometric arrangement and material characteristics (conductors, insulation, shield etc.)
• Modeling of parallel systems and their mutual interaction through couplings
• Individual consideration of cable structure and arrangement with conductors, shields and armoring

Solution

The calculation of electrical parameters of overhead lines and cables (LEIKA) from geometrical arrangements and material characteristic values is made possible by the PSS?SINCAL Platform. The determined parameters serve as input data for load flow, short circuit, influence calculation and other calculation methods.

• Consideration of any arrangement and types of conductors and single cables
• Overhead lines are calculated with any number of parallel systems of different voltages and any number of ground cables
• Calculation of cables with concentric shields or metal sheaths or armor, additional common sheaths around a three-phase system and parallel ground conductors
• Line and cable characteristic values can be calculated at operating frequency and at higher frequencies up to several kHz
• Output of coupling data for PSS?SINCAL and for the expert mode (Exp Mod) in PSS?NETOMAC
