Abstract: A method, controller, wind turbine, and computer program product are disclosed for collecting data from wind turbines in a wind farm. An example method generally includes receiving, from a client device, a subscription request identifying a plurality of data points to collect from a set of wind turbines. A wind farm server establishes a client interface with the client device. The wind farm server receives data points form the plurality of wind turbines and buffers the identified collected data points from the set of wind turbines in a data repository. Through the client interface, the wind farm server receives a request for data points collected from at least one wind turbine over a specified time period, and responsive to the request, transmits the requested data points to the client device. The wind farm server also may push collected data points from wind turbines to a data analysis system.

Abstract: A valve arrangement comprising a valve housing, a valve inlet, a valve outlet and a diaphragm assembly for controlling a fluid flow through the valve housing from the valve inlet to the valve outlet, the diaphragm assembly comprising a diaphragm and a diaphragm plate at least partially covering the diaphragm, the diaphragm comprising one or more equalization holes passing through the diaphragm and the diaphragm plate comprising one or more equalization openings passing through the diaphragm plate, the equalization holes being aligned with the equalization openings. The diaphragm assembly comprises an engagement zone engaging the diaphragm in order to rotationally fix the diaphragm and the diaphragm plate with respect to each other so that the equalization holes will keep aligned with the equalization openings to ensure proper function of the valve arrangement at all times.

Abstract: The present invention relates to a valve arrangement (1) comprising a valve housing (2), a valve inlet (3), a valve outlet (4) and a diaphragm assembly for controlling a fluid flow through the valve housing (2) from the valve inlet (3) to the valve outlet (4), the diaphragm assembly comprising a diaphragm (5) and a diaphragm plate (6) at least partially covering the diaphragm (5), the diaphragm (5) comprising one or more equalization holes (13) passing through the diaphragm (5) and the diaphragm plate (6) comprising one or more equalization openings (12) passing through the diaphragm plate (6), the equalization holes (13) being aligned with the equalization openings (12). According to the invention, the diaphragm assembly comprises an engagement zone engaging the diaphragm (5) in order to rotationally fix the diaphragm (5) and the diaphragm plate (6) with respect to each other. This has the effect that the equalization holes (13) will keep aligned with the equalization openings (12).
