Up to now, the oscillating water column devise with Wells turbine and electric generator will be one of the most prospective concepts for wave power generating system. The theoretical and experimental approaches have been developed to estimate the interaction of incident waves and the water elevation in the air chamber. Since the incident wave power of north coast in Fukui is seasonally changed from 2kW/m in summer to 20kW/m in winter, it is necessary for a power control device to improve the efficiency of Wells turbine. This paper is concerned with the feed back control system to make it optimum to adjust the air flow area of Wells turbine. A simulation model is proposed for the feed back control system consisting of the displacement of oscillating water column as the input and the revolution of Wells turbine as the output. Numerical simulations were carried out for both the constant air flow area without control and optimum air flow area with control. Finally the results of numerical simulation indicate that the turbine power with control is up to twice as much as the case without control.
