Northing Calibration in FLASC#
Northing calibration, that is the detection of bias and changes in measurements of turbine yaw are important for many of the analysis in FLASC. This notebook demonstrates the use of several of these tools in FLASC for the calibration of northing measurements.

Generate data set to illustrate operations#
For simplicity assume a fixed wind speed and turbulence intensity and uniform wind direction. Perturb the wind direction by random noise
# Set wind direction to step from 90 to 270, in steps that are 600 long and 10 degrees wide
wind_directions = np.linspace(90, 270, 10)
wind_directions = np.tile(wind_directions, 600)
wind_directions = np.sort(wind_directions)
# Apply noise
np.random.seed(0)
noise = np.random.normal(0, 5.0, wind_directions.shape)
wind_directions = wind_directions + noise
# Set a FLORIS time series object

wind_directions=wind_directions, wind_speeds=8.0, turbulence_intensities=0.06
)
# Calculate FLORIS solution
fm.set(wind_data=time_series)
fm.run()
turbine_powers = fm.get_turbine_powers()
# Add random noise to the power output
turbine_powers = turbine_powers + np.random.normal(0, 25.0, turbine_powers.shape)

Cross-Check Northing calibration#
crosscheck_northing_offset_consistency is a function to check if the relative offset between turbines is consistent. If the offset is consistent, then we know we can find a single offset value that would align the two turbine's northings. If this is not the case, one or both turbines likely experience jumps in their nacelle calibration throughout the timeseries.

df=df_scada_marked_faulty_northing_drift, fm=fm, plot_figure=True, bias_timestep=td(days=1)

crosscheck_northing_offset_consistency detects that T002 contains a probable jump, one solution is to then remove T002's wind direction data from consideration however this is not done in this notebook as we next take advantage of HOGER recalibration. The code to do this is included below in comments
# # Mark wind direction measurements of turbines with inconsistent calibration as faulty
# faulty_turbines = [not s == "clean" for s in turb_wd_consistency]
# for ti in np.where(faulty_turbines)[0]:
# df_scada_marked_faulty_northing_drift["wd_{:03d}".format(ti)] = np.nan
Homegenization with HOGER#
The homogenize function implements the HOGER method for recalibrating northing measurements. HOGER was developed by Paul Poncet (engie-paul-poncet)
and Thomas Duc (engie-thomas-duc) of Engie, and Rubén González-Lope (rglope) and Alvaro Gonzalez Salcedo (alvarogonzalezsalcedo) of CENER within the TWAIN project.
The homogenize will remove apparent jumps in northing correction (but does not confirm the final level is unbiased overall)
df_scada_non_homogenized = df_scada.copy()
df_scada_homogenized, d2 = homogenize_hoger(df_scada_marked_faulty_northing_drift, threshold=10)

The HOGER homeginization removes changes in northing calibration of turbines with respect to others, however the final selected value may contain a steady offset, as happens in this case

Step 4: Estimate the biases of the remaining turbines#
Now that we know the wind direction bias of a single turbine, we roughly know where true north lies. What we can now do is simply calculate the average offset between the wind direction of any turbine and this northing-calibrated wind direction. The wind direction bias for that turbine is likely very close to this number. We use this as a first guess for the energy-ratio-based bias estimation, and optimize within +- 5 degrees within this initial value.
def estimate_biases_with_reference_wd(df_scada, fm, wd_ref):
# Now use this knowledge to estimate bias for every turbine
num_turbines = len(fm.layout_x)
wd_bias_list = np.zeros(num_turbines)
for ti in range(num_turbines):
# Calculate the offset between this turbine's wind direction and that
# of the calibrated (reference) wind direction. Note that 'wd_ref' may
# also be a met mast' wind direction signal, if available. The offset
# between a turbine's wind direction and wd_ref is very likely to be
# the bias or close to the bias in this turbine's northing.
wd_test = df_scada["wd_{:03d}".format(ti)]
x0, _ = flopt.match_y_curves_by_offset(
wd_ref, wd_test, dy_eval=np.arange(-180.0, 180.0, 2.0), angle_wrapping=True
)
# Then, we refine this first guess by evaluating the cost function
# at [-5.0, 0.0, 5.0] deg around x0, and let the optimizer
# converge.
x_search_bounds = np.round(x0) + np.array([-5.0, 5.0])
# Calculate and save the results to a list

Step 6: Deal with inter-turbine faults#
Deal with faults at one turbine causing issues at another turbine. For example, if a turbine is shedding a wake on a second turbine, then for a fair comparison both of these two turbines should be operating normally. If the upstream turbine is curtailed or offline, the power production of the downstream turbine also changes. Hence, if we are unsure about the operating mode of one machine, we cannot make accurate FLORIS predictions on the second turbine either. In this scenario, we would classify the second turbine's measurement as faulty too, because of this.

# Filter the measurements for each turbine: make sure all
# other turbines affecting this turbine's
# power production are marked as good measurements. If they are not,
# then classify this turbine's
# measurement as faulty too.
num_turbines = dfm.get_num_turbines(df)

# Assign a reference wind direction for this turbine. In this case,
# we have such a small farm so we assume that the farm average wind
# direction of representative of every turbine.
