Methods for data from multiple wind towers:
1. Collect data on two wind towers in existing wind farms or adjacent areas.
2. Data grouping.
3. Test and process each data set separately.
4. Initial drawing of roughness lines.
5. Use the twin tower method to determine the roughness value of each local area.
6. Determine whether the existing wind farm is commissioned. Otherwise, the roughness value is determined.
7. Refine the roughness lines of existing wind farms.
8. Establish an expression to calculate the roughness value of an existing wind farm after its commissioning.
9. Use the twin tower method to determine the roughness value of the existing wind farm area.
Processing theodolite wind measurement data
You can consider this method:
CoConnect a purely resistive fixed load with sufficient power to the generator, and install a wind speed sensor near the wind turbine (the unit price is about 400 yuan). Use a computer to synchronously measure the generator output voltage and wind speed at intervals (e.g. 5 minutes) and record the data. Then, the two obtained data sets are calculated and analyzed to obtain the generator output power at different wind speeds.
The key here is that you need a multimeter with RS232 output (or other interface), and the voltage signal (or pulse signal) output from the wind speed sensor must be converted before it can enter the computer. .
A single
theodolite
can only measure elevation and direction angles. Height is calculated from climb speed and cast time.
Double
Theodolite
Utiread the trigonometric method for calculating the spatial coordinates of the ball.
Speed is calculated using distance time.
You must provide more detailed formulas or conditions for writing a program.
