WT Turbulence 1Ch

The WT Turbulence 1Ch calculates the mean of the wind velocity, the turbulence, and the turbulence intensity according to the standard EN 61400-1. As input signal, the wind velocity is required. The output values are updated in a cycle of 10 minutes.

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration Options

• Num Cycles 10Min: Indicates the number of cycles that fit in the time interval for the calculation, according to EN 61400-1 this is a ten minutes interval.

Output Values

• Mean: Mean of the wind velocity.
• Turbulence: Turbulence of the wind. According to EN-standard this is the standard deviation of the wind velocity over a time interval of 10 minutes.
• Turbulence Intensity: Intensity of the wind turbulence.

Standard HMI Controls

For the WT Turbulence 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:

1. The WindTurbulence control visualizes the output values Mean, Turbulence and Turbulence Intensity.

2. The Table Control or Multivalue Control visualizes all output values: Mean, Turbulence, Turbulence Intensity.

Alternatively, customer-specific HMI controls can be mapped in the WT Turbulence 1Ch algorithm using the Mapping Wizard.
