4 Output power v. s. stream velocity of water tunnel is shown in Table I. IV. Simulation In order to verify the results of the water tunnel simulation were performed by using MATLAB/Simulink. Modeling of the tidal current power system is shown in Figure 4. Fig. 4. Modeling of Tidal Current Power Generation System Fig. 5 Output Power vs. Stream Velocity Figure 5 is output power with respect to velocity. Measurement results in the water tunnel and simulation results show the same tendency. Fig. 6. Output Power v. s. Blade Radius Fig. 6 shows the generation power vs. blade radius in simulation when stream velocity is 2m/s. Maximum power generation appears when the radius of the blade is 3m. Summary In this paper, we investigated the characteristics of tidal current power generation system using a water tunnel. In order to verify the results of the water tunnel system simulation were performed using MATLAB/Simulink. Comparison of water tunnel measurement and simulation results shows the similar tendency. Output power according to the stream velocity and radius of the blade was measured. Output power increases as the stream velocity increases. However, output power vs. the radius of blade shows the maximum value at the optimum value due to the TSR characteristic.
