As interest in emergency power has increased, research on engine generators has been actively conducted. Permanent magnet synchronous generators (PMSGs) are suitable for small-capacity engine generators because they have higher efficiency and faster response than other motors. In this paper, PMSG rotational speed is controlled to extract the generator maximum power at a variable tidal velocity. The tip-speed ratio Maximum Power Point Tracking (MPPT) method has been applied to the proposed tidal power system since it is a simple method. The characteristics of the tidal turbine and the model of PMSG in the tidal power system have been presented to show the turbine operation modes at different tidal speeds.  The experimental results have validated the efficiency of the proposed controller to extract the maximum power point.
