WEng 4 Release Notes

This document describes the new features and other changes made.

Version 4.3

Build 4.3.0.152 – Release A

New features

  • Automatic sector-management rules
  • Highlight sites with non-IEC-compliant flow conditions in the main plot
  • Assessment of site-specific extreme ambient turbulence intensity
  • Import of WAsP 12 workspace files
  • Air density correction and wake modelling as in WAsP 12

Bug fixes

  • Float-to-integer conversion in WAT 4.2 was accidentally set to 'round up' instead of 'round to nearest'.
  • Previous versions confused upper limit with mean of wind-speed bins during turbulence calculations and reports.
  • Problem reading power curve files in POW format
  • Problem reading user-specified TI statistics from file
  • Problem with terrain assessment for IEC 61400-12-1 performance measurements
  • IEC 61400-12-1 measurement sector was not stored in project file

 

Version 4.00.122 Release E

  • Could close without saving work in very rare cases where network connectivity was lost
  • Locations button in non-SCM climates was causing an error

Version 4.00.0108 Release D

  • Location labels in Google Earth output have been updated
  • Script for turbulence is now fixed
  • In observed wind data time-series for Spectral Correction Extreme wind calculations: Data gaps and bad data are handled handled the same way.
  • Spectrum Correction extreme wind calculation quality check fail will result in a warning, not a refusal.

 

Version 4.00.0098 Release C

  • Google Earth launch is fixed
  • Actual site location is injected to the GEWC souvenir XML

Version 4.00.0096 Release B

 

This new release ‘Release B’ of WAsP Engineering fixes an error in the turbulence model, which was giving incorrect results for some sites at heights above 42 metres above ground level.  If you have done calculations for sites like this, they should be re-performed. The turbulence model results are not saved in the project file, but are of course embedded in report outputs and exports to the Windfarm Analysis Tool.

 

In addition, this new build restores the ability to copy and paste site locations from clipboard, which several people noticed.


Version 4.00.0093 Release A

 

New Feature:

  • Spectral-correction extreme wind analysis based on local short-term wind time series in combination with a long-term reanalysis wind time series from an internet database.

 

Improvements:

  • Vastly improved water fetch calculation speed;
  • More efficient use of flow model calculation runs, making calculations much faster;
  • The turbulent length scale is now limited to the IEC Standard value of 42 m;
  • Updated scripts;
  • Updated help file;
  • Bug fixes
