Steady parked loads (see 7.10): Loads on the parked turbine are calculated in steady wind. As the blade position is specified, the wind field need not be spatially uniform.
静止泊堆载荷(见 7.10):泊置涡轮机的载荷计算基于稳态风速。由于叶片位置已确定,风场不必具有空间均匀性。
# Steady parked loads calculation
This calculation generates wind turbine loads for a parked rotor in steady winds. This optionally includes blade, tower and other loads - see Output Control (see 7.21).
Use the Steady parked loads screen (see 7.5) to define the following parameters for the calculation:
• Steady wind speed: note that although the wind speed is steady, it need not be spatially uniform.
• Azimuth angle: the rotor azimuth position; zero means that blade 1 is pointing vertically upwards.
• Yaw angle: the nacelle angle measured clockwise from North, assuming that the wind is blowing from the North: see wind direction (see 6.9).
• Wind inclination: for non-horizontal wind flows (e.g. on the side of a hill). A positive value indicates a rising wind.
• Pitch angle: the pitch angle or aileron/flap/airbrake deployment angle - see Rotor (see 4.1).
The calculation also allows a sweep through any one of the four above angles, i.e. azimuth, yaw, wind inclination or pitch angle. Use Parameter to vary to define which angle will vary. The sweep start at the value specified above for that parameter. Specify End value to define the end of the sweep, and Step to define the step size.
# 稳态停机载荷计算
此计算生成停机转子在稳态风中的载荷。 可选地,包括叶片、塔架和其他载荷 - 参见输出控制 (参见 7.21)。
使用“稳态停机载荷”屏幕 (参见 7.5) 定义以下参数:
• 稳态风速:请注意,虽然风速是稳态的,但它不必在空间上均匀。
• 方位角:转子的方位位置;零表示叶片 1 指向垂直向上。
• 偏航角:从北向顺时针测量的吊舱角,假设风从北吹来 - 参见风向 (参见 6.9)。
• 风倾角:用于非水平风流(例如,山坡上)。 正值表示风向上升。
• 迎角:迎角或副翼/襟翼/气动刹车展开角 - 参见转子 (参见 4.1)。
该计算还允许对上述四个角度中的任何一个进行扫描,即方位角、偏航角、风倾角或迎角。 使用“参数变化”定义将变化的那个角度。 扫描从上述该参数的值开始。 指定“结束值”定义扫描的结束,并指定“步长”定义步长大小。
