Comparison of Different Configurations for Shoreline Pond Electrode Station for HVDC Transmission Systems—Part I: Electric Field Study for Frames of Linear Electrode Arrangement Based on a Simplified Analytical Model

During the design of a shoreline electrode station for High-Voltage Direct Current (HVDC) interconnections, location electrodes plays critical part, especially in development near-electric field. The basic structure is their linear placement, form successive frames, parallel to longitudinal axis breakwater, as proposed by CIGRE and implemented existing projects. However, this arrangement requires considerable breakwater length, which may not be permissible, case Stachtoroi, one two stations being built 1 GW, ±500 kV HVDC interconnection between Crete mainland Greece. This troubled preliminary study team stations, investigated other possible configurations. In paper, configurations placements frames are studied compared at level terms electric field effects (especially near-field), using an analytical simplified model superposition method, determine most appropriate that will cover respective requirements directives B4.61/2017. These arrangements practically evaluated different locations Korakia Stachtoroi Aegina Crete–mainland-Greece interconnection, resulting interesting alternative solutions.
