Abstract :
In Extra/High-Voltage (EHV/HV) power systems, power cables are chosen instead of over-head lines (OHL) at some places. In the Randstad region in the west of the Netherlands, the cable connection consists of a double circuit where each phase is connected via two parallel cables. The cables are cross-bonded every 0.9 km. A complete model is required to efficiently analyze interaction with the remainder of the connection consisting of overhead lines. This paper presents a method to build a symbolic model of the parallel connection of multiple cables per phase in a (EHV/HV) cable system, which can be the basis of transient analysis in the frequency domain of a large transmission system containing multiple parallel conductors. The model is analyzed and compared by means of a frequency scan of the system with PSCAD/EMTDC simulation.
