To provide a windmill system or wind farm considering improvement of a wind speed to a rotor.SOLUTION: A horizontal axis type windmill system includes a rotor which receives wind to rotate, a nacelle which enables the rotor to rotate, and a tower 3 in order to solve the problem. The windmill system includes a resistor 9 which shields wind flowing from the outer side of the windmill system to the rotor side. The resistor 9 is disposed at a position lower than a lower end of the rotor and is at least partially disposed between a vertical axis including a furthest position from the tower 3 in a rotation surface of the rotor and the tower 3.SELECTED DRAWING: Figure 4 【課題】ロータに対する風速の向上を考慮した風車システムまたはウィンドファームを提供することを目的とする。【解決手段】上記課題を解決するために、風を受けて回転するロータと、ロータを回転可能にするナセルと、タワー３を備える水平軸型の風車システムであって、風車システムの外側からロータ側に向かう風を遮る抵抗体９を備え、抵抗体９はロータの下端よりも低い位置に配置され、かつロータの回転面内でタワー３から最も遠い位置を含む鉛直軸線とタワー３の間に少なくとも一部が配置されることを特徴とする。【選択図】 図４
