    • A new method is proposed for determining a Nacelle Transfer Function (NTF), in which an individual NTF is provided for each wind turbine compensating for both structural effects, those that arise from the shape and configuration of the wind turbine, and environmental effects, those that are a result of the terrain or geographical location. Based on the assumption that the turbine is running correctly and SCADA data is taken over a certain period, and based on a siting model to give data on Turbulence Intensity (TI), ?pflow, shear and other atmospheric parameters (as a function of wind speed and wind direction as necessary) the NTF can be determined from a site specific power curve made generated using a computer model. The NTF is the function that gives the required site power curve over the period that data is available. Unlike, previous techniques, there is no requirement to use a met mast.
    • 提出了一种用于确定机舱传递函数(NTF)的新方法,其中为每个风力涡轮机提供单独的NTF,以补偿结构效应,由风力涡轮机的形状和构造引起的结果效应以及环境影响, 这是地形或地理位置的结果。 基于假设涡轮运行正常,SCADA数据在一段时间内被采集,并且基于选址模型给出湍流强度(TI),流量,剪切和其他大气参数(作为风的函数)的数据 速度和风向),NTF可以从使用计算机模型生成的现场特定功率曲线确定。 NTF是在数据可用时间内给出所需站点功率曲线的函数。 与以前的技术不同,没有要求使用满足的桅杆。

    • The device is designed to position a measuring sensor, especially a sensor head at an angle to the sensor shaft, precisely at the point of measurement and in the direction of a fluid flowing in a test tube, in which there is an adjuster by means of which the measuring sensor in a coaxial arrangement can be adjusted via a first adjusting motor about its axis and/or by a second adjusting motor along its axis; there is a control device communicating with an electronic computer for sensor adjustment; an adjuster coupled to the sensor to rotate in unison therewith has a rotatable pendulum which, in the position of rest transversely to the test tube axis defines the zero position of the sensor; limit positions of the pendulum are predetermined from a relative movement of the adjuster about said axis which can be photometrically converted into position signals, and the computer mathematically halves the angular adjustment calculated from the position signals received and sets the adjuster with the sensor to mechanical zero via the relevant positioning stop commands.
