摘　　要：潮流能发电机组是一种潮流驱动发电装置,可以将海流中蕴含的动能转换为人类可以直接利用的电能。本文提出了一种定桨距水平轴潮流能机组的启机控制方法,即将机组从静止待机状态过渡至发电状态,进入最大功率跟踪阶段。主要的控制方法为:首先,以转速模式控制机组离开静止状态,并加速到一定转速下运行,然后切换至转矩模式,进入最大功率跟踪控制,同时根据当前流速调整启机转速,以防止最大功率跟踪控制的失效。最后,通过仿真验证了本文启机控制方法的有效性,并能够适应不同潮流流速的启机环境。Driven by tidal current, tidal current generator is a power generation device which converts the kinetic energy contained in the current into electric energy that can be directly used by human being. This paper presents a start-up control method for a fixed pitch horizontal axis tidal current power unit, i.e. transits the unit from the static standby state to the generating state and the maximum power stage. First, start up the unit and accelerate it to a certain speed. Then switch to the torque mode for maximum power tracking control, and adjust the starting speed according to the current velocity to prevent the failure of the maximum power tracking. The simulation results show that the proposed method is effective and can adapt to the start-up environment with different tidal current velocity.
