Turbine rotational speed and mechanical torque in the oscillating water column wave energy converter change with sea states and fluctuate with instantaneous waves as wave energy has intermittent,random and fluctuating characteristics.Electromechanical conversion system combined with control strategy becomes one of the keys to maximize and stabilize the output power under variable working conditions.This paper starts by describing the working principle and the features of the oscillating water column wave energy conversion technology,then focuses on analyzing the operating circumstances,key points,topology of electromechanical conversion system and control strategies.The current state and issues are discussed and the future development trend is then predicted.
