Get dependent turbines for a test turbine for each wind direction.

Computes all turbines that depend on the operation of a specified turbine (test_turbine) for each wind direction in wd_array, using the FLORIS model specified by fm_in to detect dependencies.

Parameters:

  • fm_in (FlorisModels) -- FLORIS object of the farm of interest.

  • test_turbine (int) -- Turbine for which dependencies are found.

  • wd_array ([np.array]) -- Wind directions at which to determine dependencies. Defaults to [0, 2, ... , 358].

  • change_threshold (float) -- Fractional change in power needed to denote a dependency. Defaults to 0. (any change in power is marked as a dependency)

  • limit_number (int | NoneType) -- Number of turbines that a turbine can have as dependencies. If None, returns all turbines that depend on each turbine. Defaults to None.

  • ws_test (float) -- Wind speed at which FLORIS model is run to determine dependencies. Defaults to 9. m/s.

  • return_influence_magnitudes (Bool) -- Flag for whether to return an array containing the magnitude of the influence of the test_turbine on all turbines.

Returns:

dep_indices_by_wd (list): A 2-dimensional list. Each element of

the outer level list, which represents wind direction, contains a list of the turbines that depend on test_turbine for that wind direction. The second-level list may be empty if no turbine depends on the test_turbine for that wind direciton (e.g., the turbine is in the back row).

all_influence_magnitudes ([np.array]): 2-D numpy array of

influences of test_turbine on all other turbines, with size (number of wind directions) x (number of turbines). Returned only if return_influence_magnitudes is True.

Return type:

A tuple containing
