【Abstract】 The energy conversion principle,structure characteristics and design method of rim-driven marine current power(RMCP) system were presented. CFD simulation and prototype experiment are presented to analyze the hydrodynamic characteristic of turbine,the electromagnetic characteristic of generator and the output power characteristic of RMCP. The calculation results and experimental values showed that tip speed ratio of turbine,pitch angle of blade,rotor speed of generator and electrical have important influence to the output power of RMCP system.更多还原
