Pitch control of wind generators is usually made by the feed back control concept. However, the feed back signal, which is utilized to compensate the disturbance such as wind speed variation, is delayed due to the large rotor inertia of system, and consequently, the control strategy to keep the generated power at constant value is not effective only with the feed back control policy. This problem becomes serious where wind generators are installed in mountainous and rough complex terrain, and there are lots of wind turbulences in wind stream due to the geographical features. If large amounts of fluctuation are penetrated in power flow, this will have an effect on power system operation. TAPPI wind park at Tsugaru peninsula in Aomori prefecture is built in such a site and large amounts of power variations have been observed so far. Hence, this paper presents a new control strategy to reduce the power fluctuations by introducing feed forward control.
