“…Among all the used equipment, the electric power cable, which connects the platform (topside) to the VSDs located on the seabed, has the highest cost of implementation. Due to the higher inherent capacitance of cables (Akihiro Ametani, 2015), these may have parallel resonances depending on the load being actuated (Merhej and Nichols, 1992), (Liang and Jackson, 2009), increasing the electrical stress on the cable and degrading the Total Harmonic Distortion (THD) of voltages on the topside. To reduce costs and complexity of marinization of equipment, a three-phase diode bridge is used for converting alternating current (ac) to direct current (dc), in order to make the interface between the VSD and the underwater engines for oil extraction.…”

This paper presents a project method of the direct current link in order to decouple the rectification and inversion stages present in power electronics converters in a subsea power system, showing the calculation memories of the capacitors to be used in Variable Speed Drives that drive subsea loads. In order to observe the influence of harmonics on the subsea power system and on the voltage of the direct current link, the entire system was modeled with the PSCAD/EMTDC electromagnetic transient software.
