INVESTIGATION OF OFFSHORE DC STATION WITH DISTRIBUTED POWER COLLECTION AND CASCADED BOOSTING-VOLTAGE TOPOLOGY: A COMPREHENSIVE STUDY

– In order to collect DC power and boost DC voltage for offshore DC stations, the present research uses a distributed power-collection and cascaded boosting voltage (DPCB) topology made up of several cascaded single active bridges (SABs). In contrast, HVDC stations use the conventional concentrated power-collection and boosting voltage (CPCB) framework. It has high DC voltage boosting powers, is simple to build, is affordable, and offers a low system error rate. The next three variables are looked at. After first determining the DPCB topology with its circuit equations, the phase-shifting control approach is applied to further investigate the operational mechanism. The system minimal signal model is then used to construct a fuzzy control strategy. Third, a fault tolerance strategy with projected power ratio is developed to stop the DPCB station from failing if part of the SABs and generators fail. A significant power differential exists due to windward and wind turbine siting factors. The viability and efficacy of the designed DPCB station with its strategy are finally validated using simulation findings.
