![]() ![]() In this study, SCADA system consists of four 3MW class wind turbines and twenty-four 100kW class wave force generator.Floating offshore wind turbine technology has seen an increasing and continuous development in recent years. We have designed a protocol conversion device based on real-time Linux for the communication between Modbus and IEC61850. In order to test the proposed SCADA system and algorithm, we have developed the wind-wave simulator based Modbus. It was made to compensate the limitations of the legacy industrial protocols such as Modbus. IEC61850 is an international standard for electrical substation automation systems. The SCADA system is essential to perform the algorithm like proportional distribution and data acquisition, monitoring, active power, reactive power control in hybrid power generation system. ![]() We have developed an unified SCADA(Supervisory Control and Data Acquisition) system which can be used to monitor and control PCS(Power Conversion System) based on IEC61850. This paper suggests a structure of power control system in floating wave-offshore wind hybrid power generation system. From the results, it was confirmed that the topology optimization might be a useful tool to design the conceptual arrangement of main structural members for a newly developed offshore structure such as the floating type WHPGS. The topology optimization of WHPGS platform was performed using the HDM, and then the conceptual arrangement of main structural members was suggested. Boundary condition was realized using inertia relief method. Loading conditions for the structural analysis included the analysis results from the hydrodynamic analysis and the weights of WHPGS. ![]() Hydrodynamics analysis was carried out to calculate pressure on platform and tension forces in mooring lines induced from the offshore environmental loads such as design wave and current. For the conceptual platform design of WHPGS, FEA model was created and then the structural analysis was performed considering offshore environmental loads at installation site. From the results of the simplified design problem, the HDM was applied to the topology optimization of platform of WHPGS. Two topology optimization theories, density method (DM) and homogenization design method (HDM) were used to check which one is more effective for a simplified structural design problem prior to the topology optimization of platform of WHPGS. This study aims to review a topology optimization based on finite element analysis (FEA) for conceptual design of platform in the 10MW class floating type wave-wind hybrid power generation system (WHPGS). ![]()
