Embodiment Construction

[0049] According to one embodiment, at least one failure condition of at least one component (eg a bearing) of the wind turbine is detected. After a failure state is identified (for example using values ​​of vibration or noise as measured by a microphone or accelerometer), the remaining producible energy (also referred to as residual power generation (RGP)) is estimated. In this context, the RGP can be considered as the distribution of kWh remaining until component failure at a given instance of time. In contrast to conventional considerations of remaining useful life (RUL), RGP is independent of the need for continuous operation. Thus, according to embodiments of the present invention, RGP may be directly associated with performance gains, and thus, with costs involved in operation and maintenance.

[0050] The basic method for estimating remaining producible energy (RGP) can be based on deep learning architectures known as recurrent neural networks (RNNs), such as figure 1...

Abstract

It is described a method and arrangement of estimating replacement schedule of a, in particular mechanical, component of a wind turbine, the method comprising: estimating remaining producible energy (5, 11, 13, 15) until this component is to be replaced.

Description

technical field [0001] The present invention relates to a method of estimating the replacement schedule of components of a wind turbine, to a method of operating a wind turbine and also to an arrangement for estimating the replacement schedule of components of a wind turbine. Background technique [0002] Wind turbines include several components that are prone to wear due to operation, or even malfunction or damage. In particular, mechanical components such as bearings, especially of the main rotating shaft, may be subject to wear and eventual failure. Therefore, parameters related to the (health) state of one or more wind turbines or one or more wind turbine components have to be taken into account when controlling the operation of the wind turbines. These parameters may include temperature, noise, vibration and other state-related measurements, such as those performed directly at the component. Analysis of these measurements may allow the operator to assess at what point...
